Abstract
Background Diabetic foot-induced sepsis is a serious complication associated with increased disability and mortality in hospitalized patients. Early prediction of admission and detection effectively improve treatment options and prevent further deterioration. This study aims to evaluate the clinical value of the neutrophil-to-lymphocyte ratio (NLR) and prognostic nutritional index (PNI) to predict the risk of sepsis in patients with diabetic foot ulcers (DFU). Methods Retrospective analysis was performed on 216 patients who were admitted to the Fujian Medical University Union Hospital between January 2015 and December 2022. Patients with DFU were divided into the non-sepsis (n = 166) and the DFU-induced sepsis (n = 50) groups. The independent factors of DFU-induced sepsis were determined by univariate and multivariate logistic regression analyses. A receiver operating characteristic (ROC) curve was performed to compare the area under the curves (AUC) of PNI and NLR. Results Multivariate logistic regression analysis revealed that the PNI, NLR, international normalized ratio (INR), thrombin time (PT), and C-reactive protein (CRP) were independent prognostic factors for DFU-induced sepsis. After adjusting for potential confounders, the adjusted odds ratios of NLR for DFU-induced sepsis were 1.121 (1.072-1.172), 1.132 (1.077-1.189), and 1.080 (1.022-1.142), while those of PNI were 0.912 (0.873-0.953), 0.902 (0.856-0.950), and 1.004 (1.001-1.006). Moreover, the AUC of NLR was significantly greater than that of CRP (0.790, 95% CI: 0.689-0.891, p < 0.001 vs. 0.780, 95% CI: 0.686-0.873, p < 0.001). Conclusion NLR and PNI have been regarded as readily and independently predictive markers in patients with DFU-induced sepsis. NLR is critical for the early detection and effective treatment of DFU-induced sepsis and is superior to CRP.

Abstract
Non-healing wounds are among the main causes of morbidity and mortality. We recently described a novel, serum-free ex vivo expansion system, the quantity and quality culture system (QQc), which uses peripheral blood mononuclear cells (PBMNCs) for effective and noninvasive regeneration of tissue and vasculature in murine and porcine models. In this prospective clinical study, we investigated the safety and efficacy of QQ-cultured peripheral blood mononuclear cell (MNC-QQ) therapy for chronic non-healing ischemic extremity wounds. Peripheral blood was collected from 9 patients with 10 chronic (>1 month) non-healing wounds (8 males, 1 female; 64-74 years) corresponding to ischemic extremity ulcers. PBMNCs were isolated and cultured using QQc. Within a 20-cm area surrounding the ulcer, 2 × 107 cells were injected under local anesthesia. Wound healing was monitored photometrically every 2 weeks. The primary endpoint was safety, whereas the secondary endpoint was efficacy at 12-week post-injection. All patients remained ambulant, and no deaths, other serious adverse events, or major amputations were observed for 12 weeks after cell transplantation. Six of the 10 cases showed complete wound closure with an average wound closure rate of 73.2% ± 40.1% at 12 weeks. MNC-QQ therapy increased vascular perfusion, skin perfusion pressure, and decreased pain intensity in all patients. These results indicate the feasibility and safety of MNC-QQ therapy in patients with chronic non-healing ischemic extremity wounds. As the therapy involves transplanting highly vasculogenic cells obtained from a small blood sample, it may be an effective and highly vasculogenic strategy for limb salvage.

Diabet Med 2021; 38:e14568. [PMID: 33772856 DOI: 10.1111/dme.14568] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2020] [Revised: 02/18/2021] [Accepted: 03/24/2021] [Indexed: 01/01/2023]
Abstract
INTRODUCTION We previously demonstrated in both a longitudinal study and in meta-analysis (pooled relative-risk RR, 2.45) that all-cause mortality is significantly higher in people with diabetes foot ulceration (DFU) than with those without a foot ulcer. In this prospective study, we looked at the factors linked to mortality after presentation to podiatry with DFU. METHODS Ninety-eight individuals recruited consecutively from the Salford Royal Hospital Multidisciplinary Foot Clinic in Spring 2016 were followed up for up to 48 months. Data concerning health outcomes were extracted from the electronic patient record (EPR). RESULTS Seventeen people (17) had type 1 diabetes mellitus, and 81 had type 2 diabetes mellitus. Thirty-one were women. The mean age (range) was 63.6 (28-90) years with maximum diabetes duration 45 years. Mean HbA1c was 72 (95% CI: 67-77) mmol/mol; 97% had neuropathy (International Working Group on the Diabetic Foot (IWGDF) monofilament); 62% had vascular insufficiency (Doppler studies); 69% of ulcers were forefoot, and 23% of ulcers were hind foot in location. Forty of 98 (40%) patients died in follow-up with 27% of death certificates including sepsis (not foot-related) and 35% renal failure as cause of death. Multivariate regression analysis indicated a 6.3 (95% CI: 3.9-8.1) fold increased risk of death with hind foot ulcer, independent of age/BMI/gender/HbA1c/eGFR/total cholesterol level. CONCLUSION This prospective study has indicated a very high long-term mortality rate in individuals with DFU, greater for those with a hind foot ulcer and shown a close relation between risk of sepsis/renal failure and DFU mortality, highlighting again the importance of addressing all risk factors as soon as people present with a foot ulcer.

Abstract
BACKGROUND The aim of the present study was to assess the effects of the extent of heel ulceration on the outcomes of limb threatening critical ischemia due to isolated infrapopliteal disease. METHODS A retrospective review identified 989 patients with isolated infrapopliteal disease and heel ulceration treated from 2001 to 2018. The heel was defined as the back of the foot, extending from the Achilles tendon to around the plantar surface and covering the apex of the calcaneum bone. Heel ulceration was categorized into three groups by area: <5 cm2, 5 to 10 cm2, and >10 cm2. The interventions were endovascular, open bypass, major amputation, and wound care. An intention-to-treat analysis by patient group was performed. The 30-day outcomes and amputation-free survival (AFS; survival without a major amputation) were evaluated. RESULTS Of the 989 patients, 384 (58% male; average age, 65 years; n = 768 vessels) had undergone isolated endovascular tibial intervention, 124 (45% male; average age, 59 years) had undergone popliteal tibial vein bypass for limb threatening critical ischemia, 219 (52% male; average age, 67 years) had undergone major amputation, and 242 (49% male; average age, 66 years) had received wound care. No difference was found in the 30-day major adverse cardiac events in the endovascular and open bypass groups, with significantly more events in the major amputation group (P = .03). The 30-day major adverse limb events and 30-day amputation rates were equivalent between the open bypass and endovascular groups. The 5-year AFS rate was superior in the open bypass group (37% ± 8%; mean ± standard error of the mean) compared with the endovascular group (27% ± 9%; P = .04). The wound care group had a 5-year AFS rate of 20% ± 9%, which was not significantly different from that of the endovascular group. Patients with heel ulcers of <5 cm2 had better AFS (47% ± 8%) than those with 5- to 10- cm2 heel ulceration (24% ± 9%). Heel ulcers >10 cm2 were associated with markedly worse 5-year AFS outcomes (0% ± 0%). The presence of end-stage renal disease, osteomyelitis, uncontrolled diabetes (hemoglobin A1c >10%), and/or frailty combined with a heel ulcer >10 cm2 were predictive of poor AFS. CONCLUSIONS An increasing heel ulcer area combined with osteomyelitis and systemic comorbidities was associated with worsening 30-day outcomes and 5-year AFS, irrespective of the therapy chosen.

Wound location is independently associated with adverse outcomes following first-time revascularization for tissue loss. J Vasc Surg 2020; 73:1320-1331.

Abstract
OBJECTIVE Few studies adequately evaluate the impact of wound location on patient outcomes after lower extremity revascularization. Consequently, we evaluated the relationship between lower extremity wound location and long-term outcomes. METHODS We reviewed all patients at our institution undergoing any first-time open surgical bypass or percutaneous transluminal angioplasty with or without stenting for tissue loss between 2005 and 2014. We categorized wounds into three distinct groups: forefoot (ie, toes and metatarsal heads), midfoot (ie, dorsal, plantar, lateral, medial surfaces excluding toes, metatarsal heads, or heel), and heel. Limbs with multiple wounds were excluded from analyses. We compared rates of perioperative complications, wound healing, reintervention, limb salvage, amputation-free survival, and survival using χ2, Kaplan-Meier, and Cox regression analyses. RESULTS Of 2869 infrainguinal revascularizations from 2005 to 2014, 1126 underwent a first-time revascularization for tissue loss, of which 253 patients had multiple wounds, 197 had wounds proximal to the ankle, 100 had unreliable wound information, and 576 (forefoot, n = 397; midfoot, n = 61; heel, n = 118) fit our criteria and had a single foot wound with reliable information regarding wound specifics. Patients with forefoot, midfoot, and heel wounds had similar rates of coronary artery disease, hypertension, diabetes, and smoking history (all P > .05). Conversely, there were significant differences in patient age (71 vs 69 vs 70 years), prevalence of gangrene (41% vs 5% vs 21%), and dialysis dependence (18% vs 17% vs 30%) (all P < .05). There were no statistically significant differences in perioperative mortality (1.3% vs 4.9% vs 4.2%; P = .06) or postoperative complications among the three groups. Between forefoot, midfoot, and heel wounds, there were significant differences in unadjusted 6-month rates of complete wound healing (69% vs 64% vs 53%), 3-year rates of amputation-free survival (54% vs 57% vs 35%), and survival (61% vs 72% vs 41%) (all P < .05). After adjustment, compared with forefoot wounds, heel wounds were associated with higher rates of incomplete 6-month wound healing (hazard ratio [HR], 1.6; 95% confidence interval [CI], 1.1-2.]), major amputation or mortality (HR, 1.7; 95% CI, 1.1-2.7), and all-cause mortality (HR, 1.8; 95% CI, 1.1-3.0), but not major amputation alone (HR, 2.1; 95% CI, 0.9-4.5). In open surgical bypass-first patients, heel wounds were solely associated with an increased risk of all-cause mortality (HR, 1.7; 95% CI, 1.1-2.8), whereas heel wounds in percutaneous transluminal angioplasty-first patients were associated with an increased risk of incomplete wound healing (HR, 2.2; 95% CI, 1.3-3.7), major amputation or mortality (HR, 2.3; 95% CI, 1.1-5.4), and all-cause mortality (HR, 2.8; 95% CI, 1.1-7.2). CONCLUSIONS Heel wounds confer considerably higher short- and long-term morbidity and mortality compared with midfoot or forefoot wounds in patients undergoing any first-time lower extremity revascularization.

Abstract
Ischaemic diabetic heel ulcers are difficult to treat and prognosis is often guarded. The aim was to document our outcome of treating heel ulcers following revascularization in a predominantly diabetic Asian cohort presenting with chronic limb threatening ischaemia from Singapore. Retrospective cohort study (n = 66, 66 limbs) over a 5‐year period. Data were collected from hospital electronic health records. Outcomes included time to healing, amputation free survival (AFS), and mortality. Minimum follow‐up period was 6 months. Multivariate regression analysis was performed to look for factors associated with poor outcome. Mean age was 67.4 ± 8.8 years. 62/66 (93.9%) were diabetics. Mean wound size at presentation was 3.6 ± 2.3 cm. Mean Wound, Ischaemia, Foot Infection (WIFI) score was 5 ± 1.6. 12/66 (18%) patients had a patent posterior tibial artery pre‐operatively. Straight line flow was restored in only 31/66 (46.9) patients but 47/66 (71.2%) had successful limb salvage. Median time to wound healing was 90.0 (IQR 60‐180) days. A median of 1 (IQR 0‐2) wound debridement was required. Patients who underwent negative pressure dressing (23/66; 34.8%) required a median of 26 (IQR 13‐33) cycles to achieve healing. Amputation free survival (AFS) was 72% and 68% at 6‐ and 12‐months, respectively. Mortality rate was 16.7% and 19.7% at 6‐ and 12‐months, respectively. Low albumin level and initial Rutherford class were independent predictors of worse 6‐month AFS. Outcomes of heel ulcers post revascularisation may not be as poor as previously described. Persistent attention to wound care with multidisciplinary effort is needed for optimal healing.

Abstract
GUIDELINE SUMMARY Chronic limb-threatening ischemia (CLTI) is associated with mortality, amputation, and impaired quality of life. These Global Vascular Guidelines (GVG) are focused on definition, evaluation, and management of CLTI with the goals of improving evidence-based care and highlighting critical research needs. The term CLTI is preferred over critical limb ischemia, as the latter implies threshold values of impaired perfusion rather than a continuum. CLTI is a clinical syndrome defined by the presence of peripheral artery disease (PAD) in combination with rest pain, gangrene, or a lower limb ulceration >2 weeks duration. Venous, traumatic, embolic, and nonatherosclerotic etiologies are excluded. All patients with suspected CLTI should be referred urgently to a vascular specialist. Accurately staging the severity of limb threat is fundamental, and the Society for Vascular Surgery Threatened Limb Classification system, based on grading of Wounds, Ischemia, and foot Infection (WIfI) is endorsed. Objective hemodynamic testing, including toe pressures as the preferred measure, is required to assess CLTI. Evidence-based revascularization (EBR) hinges on three independent axes: Patient risk, Limb severity, and ANatomic complexity (PLAN). Average-risk and high-risk patients are defined by estimated procedural and 2-year all-cause mortality. The GVG proposes a new Global Anatomic Staging System (GLASS), which involves defining a preferred target artery path (TAP) and then estimating limb-based patency (LBP), resulting in three stages of complexity for intervention. The optimal revascularization strategy is also influenced by the availability of autogenous vein for open bypass surgery. Recommendations for EBR are based on best available data, pending level 1 evidence from ongoing trials. Vein bypass may be preferred for average-risk patients with advanced limb threat and high complexity disease, while those with less complex anatomy, intermediate severity limb threat, or high patient risk may be favored for endovascular intervention. All patients with CLTI should be afforded best medical therapy including the use of antithrombotic, lipid-lowering, antihypertensive, and glycemic control agents, as well as counseling on smoking cessation, diet, exercise, and preventive foot care. Following EBR, long-term limb surveillance is advised. The effectiveness of nonrevascularization therapies (eg, spinal stimulation, pneumatic compression, prostanoids, and hyperbaric oxygen) has not been established. Regenerative medicine approaches (eg, cell, gene therapies) for CLTI should be restricted to rigorously conducted randomizsed clinical trials. The GVG promotes standardization of study designs and end points for clinical trials in CLTI. The importance of multidisciplinary teams and centers of excellence for amputation prevention is stressed as a key health system initiative.

Abstract
Chronic limb-threatening ischemia (CLTI) is associated with mortality, amputation, and impaired quality of life. These Global Vascular Guidelines (GVG) are focused on definition, evaluation, and management of CLTI with the goals of improving evidence-based care and highlighting critical research needs. The term CLTI is preferred over critical limb ischemia, as the latter implies threshold values of impaired perfusion rather than a continuum. CLTI is a clinical syndrome defined by the presence of peripheral artery disease (PAD) in combination with rest pain, gangrene, or a lower limb ulceration >2 weeks duration. Venous, traumatic, embolic, and nonatherosclerotic etiologies are excluded. All patients with suspected CLTI should be referred urgently to a vascular specialist. Accurately staging the severity of limb threat is fundamental, and the Society for Vascular Surgery Threatened Limb Classification system, based on grading of Wounds, Ischemia, and foot Infection (WIfI) is endorsed. Objective hemodynamic testing, including toe pressures as the preferred measure, is required to assess CLTI. Evidence-based revascularization (EBR) hinges on three independent axes: Patient risk, Limb severity, and ANatomic complexity (PLAN). Average-risk and high-risk patients are defined by estimated procedural and 2-year all-cause mortality. The GVG proposes a new Global Anatomic Staging System (GLASS), which involves defining a preferred target artery path (TAP) and then estimating limb-based patency (LBP), resulting in three stages of complexity for intervention. The optimal revascularization strategy is also influenced by the availability of autogenous vein for open bypass surgery. Recommendations for EBR are based on best available data, pending level 1 evidence from ongoing trials. Vein bypass may be preferred for average-risk patients with advanced limb threat and high complexity disease, while those with less complex anatomy, intermediate severity limb threat, or high patient risk may be favored for endovascular intervention. All patients with CLTI should be afforded best medical therapy including the use of antithrombotic, lipid-lowering, antihypertensive, and glycemic control agents, as well as counseling on smoking cessation, diet, exercise, and preventive foot care. Following EBR, long-term limb surveillance is advised. The effectiveness of nonrevascularization therapies (eg, spinal stimulation, pneumatic compression, prostanoids, and hyperbaric oxygen) has not been established. Regenerative medicine approaches (eg, cell, gene therapies) for CLTI should be restricted to rigorously conducted randomizsed clinical trials. The GVG promotes standardization of study designs and end points for clinical trials in CLTI. The importance of multidisciplinary teams and centers of excellence for amputation prevention is stressed as a key health system initiative.
