[PMID: 33314661 PMCID: PMC8244070 DOI: 10.1111/iwj.13535] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Revised: 11/19/2020] [Accepted: 11/24/2020] [Indexed: 12/13/2022] Open
Abstract
We aimed to explore the mechanism of circular RNAs (circRNAs) and provide potential biomarkers for molecular therapy of diabetic foot ulcers (DFU). Gene expression profile of GSE114248, including five normal samples and five DFU samples, was downloaded from GEO database. Differentially expressed circRNAs (DEcircRNAs) between two groups were identified. Then, DEcircRNA‐miRNA and miRNA‐mRNA interaction was revealed, followed by the circRNA‐miRNA‐mRNA network construction. Moreover, functional and pathway analysis were performed based on mRNAs, followed by the DM‐related pathway exploration. Specific binding sites for key circRNAs and associated miRNAs were under investigation. Finally, RT‐qPCR was used to verify the candidate the relative expression level of circRNA between normal tissues and DFU. Totally, 65 DEcircRNAs were revealed between two groups, followed by 113 circRNA‐miRNA‐mRNA interactions explored. The mRNAs in these interactions were mainly assembled in functions like cell proliferation and pathways. Moreover, a total of 11 DM‐related pathways were revealed. Finally, circRNA‐miRNA specific binding‐site analysis revealed two key circRNAs, for example, circRNA_072697 and circRNA_405463, corresponding to their miRNAs. These two circRNAs were novel biomarkers for DFU. circRNA_072697 acted as a sponge of miR‐3150a‐3p in the progression of DFU via regulating KRAS. MAPK signaling pathway might contribute to the development of DFU.

Abstract
COVID-19 has created unprecedented challenges for healthcare services internationally. Many NHS organisations have cancelled outpatient clinics to release frontline clinical staff and minimise risk of patients contracting COVID-19. While many outpatient services manage chronic diseases, a number of services manage high-acuity patients. Delivery of these acute outpatient services during the pandemic has posed particular challenges and required significant service model reconfiguration. The acute diabetes foot clinic is an important example of such a service. We explore the important lessons learnt during the COVID-19 pandemic for managing high-acuity outpatient services through the context of the diabetic foot clinic. Learning can be divided into the following categories: remote and digital working, physical changes in service delivery, workforce challenges and post-pandemic preparedness. This learning is applicable to a wide range of high-acuity services during and following the pandemic. It is particularly relevant as we expand outpatient care provision to avoid hospital admissions.

Abstract
More than half of diabetic wounds demonstrate clinical signs of infection at presentation and lead to poor outcomes. This work develops coaxial sheath-core nanofibrous poly(lactide-co-glycolide) (PLGA) scaffolds that are loaded with bioactive antibiotics and platelet-derived growth factor (PDGF) for the repair of diabetic infectious wounds. PDGF and PLGA/antibiotic solutions were pumped, respectively, into two independent capillary tubings for coaxial electrospinning to prepare biodegradable sheath-core nanofibers. Spun nanofibrous scaffolds sustainably released PDGF, vancomycin, and gentamicin for 3 weeks. The scaffolds also reduced the phosphatase and tensin homologue content, enhanced the amount of angiogenesis marker (CD31) around the wound area, and accelerated healing in the early stage of infected diabetic wound repair. Antibiotic/biomolecule-loaded PLGA nanofibers may provide a very effective way to aid tissue regeneration at the sites of infected diabetic wounds.

Abstract
Background: This study reviews the mortality of patients with diabetic foot ulcers (DFU) from the first consultation with a Multidisciplinary Diabetic Foot Team (MDFT) and analyzes the main cause of death, as well as the relevant clinical factors associated with survival. Methods: Data of 338 consecutive patients referred to the MDFT center for a new DFU during the 2008–2014 period were analyzed. Follow-up: until death or until 30 April 2020, for up to 12.2 years. Results: Clinical characteristics: median age was 71 years, 92.9% had type 2 diabetes, and about 50% had micro-macrovascular complications. Ulcer characteristics: Wagner grade 1–2 (82.3%), ischemic (49.2%), and infected ulcers (56.2%). During follow-up, 201 patients died (59.5%), 110 (54.7%) due to cardiovascular disease. Kaplan—Meier curves estimated a reduction in survival of 60% with a 95% confidence interval (95% CI), (54.7–65.3) at 5 years. Cox regression analysis adjusted to a multivariate model showed the following associations with mortality, with hazard ratios (HRs) (95% CI): age, 1.07 (1.05–1.08); HbA1c value < 7% (53 mmol/mol), 1.43 (1.02–2.0); active smoking, 1.59 (1.02–2.47); ischemic heart or cerebrovascular disease, 1.55 (1.15–2.11); chronic kidney disease, 1.86 (1.37–2.53); and ulcer severity (SINBAD system) 1.12 (1.02–1.26). Conclusion: Patients with a history of DFU have high mortality. Two less known predictors of mortality were identified: HbA1c value < 7% (53 mmol/mol) and ulcer severity.

Abstract
Background: Vitamin D deficiency has been associated with an increased risk in several diabetic complications. We aimed to evaluate the association between vitamin D and diabetic foot ulcer (DFU) in patients with type 2 diabetes. Methods: Fifty one patients were included in the study and divided into two groups for study of vitamin D, cholesterol, and triglycerides in blood serum on DFU. The association between vitamin D and DFU was measured by binary logistic regression analysis. The cut point of vitamin D for DFU was assessed by the receiver operating characteristic curve. Results: Levels of 25-OH-vitamin D were lower in patients with DFU than in DM group (P < 0.0001). The AUC of 25-OH-vitamin D was 0.8254 and had an optimal cut point value (13.68 ng/ml) for the identification of DFU, with a sensitivity of 90% and a specificity of 66.67% in all patients. Multivariate logistic regression analysis indicated that the significant risk factors included 25-OH-vitamin D level (P = 0.001, OR = 0.618) and HDL-C level (P = 0.038, OR = 0.012). Conclusion: Low serum 25-OH-vitamin D level was associated with DFU. This indication was more specific than cholesterol and triglycerides levels.

Abstract
BACKGROUND Diabetic foot ulcers (DFU) are associated with high morbidity and mortality globally. Mortality in patients hospitalized for DFU in Nigeria is unacceptably high. This study was undertaken to determine factors that predict mortality in patients hospitalized for DFU in Nigeria. METHODS The current study was part of Multi-centre Evaluation of Diabetic Foot Ulcer in Nigeria (MEDFUN), an observational study conducted in six tertiary healthcare institutions across the 6 geopolitical zones of Nigeria. Consecutive type 1 or 2 diabetic patients hospitalized for DFU who consented to participate were recruited and subjected to relevant clinical, biochemical, and radiological assessments and multidisciplinary care until discharge or death. Data for type 1 diabetes mellitus (DM) patients were expunged from current mortality analysis due to their small number. RESULTS Three hundred and twenty-three type 2 DM subjects with mean age and mean duration of DM of 57.2 ± 11.4 years and 8.7 ± 5.8 years respectively participated in this study. The median duration of ulcers was 39 days with a range of 28 to 54 days and the majority (79.9%) presented with advanced ulcers of at least Wagner grade 3. Mortality of 21.4% was recorded in the study, with the highest mortality observed among subjects with Wagner grade 5. Variables significantly associated with mortality with their respective p values were DM duration more than 120 months (p 0.005), ulcer duration > 1 month (p 0.020), ulcer severity of Wagner grade 3 and above (p 0.001), peripheral arterial disease (p 0.005), proteinuria (p < 0.001), positive blood cultures (p < 0.001), low HDL (p < 0.001), shock at presentation (p < 0.001), cardiac failure (p 0.027), and renal impairment (p < 0.001). On Multivariate regression analysis, presence of bacteraemia (OR 5.053; 95% CI 2.572-9.428) and renal impairment (OR 2.838; 95% CI 1.349-5.971) were significantly predictive of mortality independent of other variables. CONCLUSIONS This study showed high intra-hospital mortality among patients with DFU, with the majority of deaths occurring among those with advanced ulcers, bacteraemia, cardiac failure, and renal impairment. Prompt attention to these factors might help improve survival from DFU in Nigeria.

Abstract
AIMS This long-term prospective study evaluated limb amputation and mortality after the first neuropathic diabetic foot ulcer (DFU). METHODS A total of 2880 patients with neuropathic DFU (DFU group) and a similar number of patients of diabetes without DFU (nDFU) matched for age and diabetes duration were prospectively assessed at five referral-centers over 14 years. Pre-defined outcome was death during follow-up. Various diabetic co-morbidities and amputation were assessed as mortality predictors. RESULTS Overall, 501 (17.4%) patients in DFU group died compared to 89 (3.1%) (p < 0.01) in nDFU group during a median follow-up of 7(1-14) years. The 5- and 10-year mortality was 22% and 71% in the DFU group with a median survival of 7.72 (7.37-8.08) years compared to 3% (p < 0.01) and 5% (p < 0.01) and survival of 12.6 (10.5-12.7) years (p < 0.001) in nDFU group. 29.3% patients had limb amputations. The mortality risk was independent of glycemic control [OR 1.03 (0.80-1.32; p = 0.83)]. However, diabetes duration > 10 years [OR 1.31(1.02-1.70, p = 0.035)], nephropathy [OR 1.47 (1.04-2.09, p < 0.030)], minor 1.85 (1.40-2.44; p < 0.001) or major amputation 2.96 (2.01-4.34, p < 0.001)] predicted mortality. CONCLUSIONS Every one-in-three individual with neuropathic DFU has amputation and every sixth individual has an early demise. Prevalent nephropathy and incident amputation following DFU predicts mortality.

Abstract
BACKGROUND In 2007, we reported a summary of data comparing diabetic foot complications to cancer. The purpose of this brief report was to refresh this with the best available data as they currently exist. Since that time, more reports have emerged both on cancer mortality and mortality associated with diabetic foot ulcer (DFU), Charcot arthropathy, and diabetes-associated lower extremity amputation. METHODS We collected data reporting 5-year mortality from studies published following 2007 and calculated a pooled mean. We evaluated data from DFU, Charcot arthropathy and lower extremity amputation. We dichotomized high and low amputation as proximal and distal to the ankle, respectively. This was compared with cancer mortality as reported by the American Cancer Society and the National Cancer Institute. RESULTS Five year mortality for Charcot, DFU, minor and major amputations were 29.0, 30.5, 46.2 and 56.6%, respectively. This is compared to 9.0% for breast cancer and 80.0% for lung cancer. 5 year pooled mortality for all reported cancer was 31.0%. Direct costs of care for diabetes in general was $237 billion in 2017. This is compared to $80 billion for cancer in 2015. As up to one-third of the direct costs of care for diabetes may be attributed to the lower extremity, these are also readily comparable. CONCLUSION Diabetic lower extremity complications remain enormously burdensome. Most notably, DFU and LEA appear to be more than just a marker of poor health. They are independent risk factors associated with premature death. While advances continue to improve outcomes of care for people with DFU and amputation, efforts should be directed at primary prevention as well as those for patients in diabetic foot ulcer remission to maximize ulcer-free, hospital-free and activity-rich days.

Abstract
BACKGROUND Diabetic foot ulcers portend an almost twofold increase in all-cause mortality compared with diabetes on its own. AIM To investigate the association between diabetic foot ulcers and risk of death. METHODS We performed a meta-analysis of all observational studies investigating the association between diabetic foot ulcers and all-cause mortality. Risk ratios and risk differences were pooled in a random-effects model. The I2 statistic was used to quantify heterogeneity between studies. RESULTS Altogether, we identified 11 studies that reported 84 131 deaths from any cause in 446 916 participants with diabetes during a total of 643 499 person-years of follow-up. The crude event rate for all-cause mortality in individuals with diabetes who did not develop foot ulceration was 22% lower at 181.5 deaths (per 1000 person-years) than in those who developed foot ulcers (230.8 per 1000 person-years). Diabetic foot ulceration was associated with an increased risk of all-cause mortality (pooled relative risk 2.45, 95% CI 1.85-2.85). We did not observe any tangible differences in risk of all-cause mortality from diagnosis in studies reporting a mean duration of follow-up of ≤3 years (relative risk 2.43, 95% CI 2.27-2.61) or >3 years (relative risk 2.26, 95% CI 2.13-2.40) years. Funnel plot inspection revealed no significant publication bias among studies included in this meta-analysis. CONCLUSIONS Our study shows an excess rate of all-cause mortality in people with diabetic foot ulceration when compared to those without foot ulceration. It is imperative that early interventions to prevent foot ulceration and modify cardiovascular disease risk factors are put in place to reduce excess mortality.

Abstract
BACKGROUND Diabetic foot ulceration is a devastating complication of diabetes mellitus and is a major source of morbidity and mortality. So far, there are few published data on diabetic foot ulcers and its determinants among diabetic patients on follow-up at Jimma Medical Center. Hence, the aim of this study was to assess the prevalence of diabetic foot ulcer and its determinants among patients with diabetes mellitus at Jimma Medical Center. METHODS A hospital-based cross-sectional study was conducted from June 1 to August 30, 2019, and systematic random sampling technique was applied. The total number of study subjects who participated in the study was 277. Data were collected using an interview-administered structured questionnaire. Data were entered into EpiData version 3.1 and exported to SPSS version 20 software for analysis. Analysis was done using descriptive statistics and logistic regression. A variable having a p value of <0.25 in the bivariate model was subjected to multivariate analysis to avoid confounding the variable's effect. Adjusted odds ratios (AOR) were calculated at 95% confidence interval and considered significant with a p value of <0.25 in the bivariate model was subjected to multivariate analysis to avoid confounding the variable's effect. Adjusted odds ratios (AOR) were calculated at 95% confidence interval and considered significant with a. RESULT The mean of age of participants was 50.1 ± 14.19 years. More than three-fourths of participants (82.7%) were type 2 DM. The mean duration of diabetic patients was 6.00 ± 5.07 years. The prevalence of diabetic foot ulcer was 11.6% among study participants. According to multivariate logistic regression analysis, previous history of ulceration (AOR = 5.77; 95% CI: 2.37, 14.0) and peripheral neuropathy (AOR = 11.2; 95% CI: 2.8, 44.4) were independent predictors of diabetic foot ulcer. CONCLUSION The prevalence of diabetic foot ulcer was 11.6%. Previous history of ulceration and peripheral neuropathy were associated with diabetic foot ulcer. The health care providers are recommended to thoroughly give emphasis during follow-up of patients who had previous history of ulceration and peripheral neuropathy in order to decrease the occurrence of diabetic foot ulcer.

Abstract
AIMS We studied mortality in individuals of diabetes with or without Charcot neuroarthropathy (CN). METHODS People attending diabetic foot care facility with CN of foot (Cohort 1) were prospectively evaluated. Details pertaining to the duration of diabetes, microvascular and macrovascular complications, foot ulcer, amputation and mortality outcomes were recorded and compared with those without foot complications (Cohort 2) by multivariate logistic regression. RESULTS Data for 260 individuals of diabetes with CN and 520 individuals without CN were analysed. Mean age at presentation with CN was 55.8 ± 9.1 years, and duration of diabetes was 12.9 ± 7.8 years. 39.8% individuals with CN had foot ulcer, and 15.3% had amputation. People with CN were younger (55 ± 9.1 vs. 59.9 ± 8.1 years, p < 0.001) and had higher prevalence of microvascular complications. A total of 39 (15%) individuals with CN and 50 (9.8%) (p = 0.03) individuals without CN died during median follow-up of 40(24-51) months. People with CN had 2.7 times (OR 2.72, 95% CI 1.4-5.2, p = 0.003) increased mortality risk when matched for potential confounders. Prevalent CAD and low eGFR predicted higher mortality in people with CN. CONCLUSIONS People with Charcot neuroarthropathy have almost three times increased risk of mortality despite being younger at presentation.

Abstract
Aim: We investigated the healing effects of conditioned medium (CM) derived from a physiological 3D culture system engineered to use an extracellular matrix/stromal vascular fraction (SVF) gel enriched for adipose on diabetic wounds in rats. This CM (Gel-CM) was compared with that from a 2D culture system that used SVF cells (SVF-CM). Materials & methods: Keratinocytes, fibroblasts and wounds were treated with Gel-CM and SVF-CM, and cytokine levels in the CM types were quantified. Results: Proliferation and migration of keratinocytes and fibroblasts were significantly higher after treatment with Gel-CM than with SVF-CM. Collagen secretion by fibroblasts and wound closure were highly stimulated by Gel-CM. Proteomic analyses revealed a higher concentration of growth factors in Gel-CM than in SVF-CM. Conclusion: Gel-CM is a promising therapeutic option for treating diabetic wounds.

Abstract
Introduction: Recent applications of ultrasonic probes include cataract removal and tennis elbow treatment. Early data support the use of ultrasonic probe debridement in the treatment of recalcitrant diabetic foot ulcers. No data are available concerning the potential antibacterial properties of the clinical grade, lower energy ultrasound probes. We investigated the effect of a clinically available ultrasonic debridement probe with respect to bacterial viability. Methods: A commercially available Tenex sonication machine with a Tx1 probe was used for this study. Three bacterial strains, aerobic and anaerobic, were investigated, G-negative (Porphyromonas gingivalis) and G-positive bacteria (Staphylococcus aureus and Streptococcus gordonii). These bacteria were cultured and tested with sonication for varying lengths of time (10, 30, 60, and 120 s). The tested bacterial samples were plated, the number of colonies on each plate counted, and the anti-bacterial effect was calculated. Statistical analysis was conducted using a one-way analysis of variance. Results: Sonication exhibited a significant time-dependent antibacterial effect. Statistically significant anti-bacterial effect was observed in all three species tested. When comparing the kill rate between the control and 120 s of sonication; S. gordonii had a 34% kill rate, S. aureus had a 60% kill rate, and P. gingivalis had a 64% kill rate. When comparing control to all of the time intervals tested, S. aureus kill rate was statistically significant at all times, S. gordonii was statistically significant at all times above 10 s, and P. gingivalis was only statistically significant at 120 s. Conclusion: This study demonstrates that a clinically available ultrasonic probe has an antibacterial effect against a wide spectrum of gram-positive, gram-negative, aerobic and anaerobic bacterial species. This may partially explain the dramatic healing of long-standing recalcitrant diabetic ulcers debrided with this device and may have a place in treating pathologies with bacterial mechanisms.

Abstract
Background In patients with diabetes, foot amputations among Black patients have been historically higher compared with White patients. Using the National Inpatient Sample database, we sought to determine if disparities in foot amputations and resource utilization have improved over time. We hypothesized there would be improvements and reduced differences in foot amputations between the two races as quality of care and access to healthcare has improved. Methods and findings Patients over 18 years old with a principal diagnosis of diabetic foot complications and secondary diagnosis of Diabetes Mellitus were selected. We compared the primary outcome of foot amputations between Black and White patients. Adjusted rates, odds ratios (aOR) and trends of foot amputations among Black and White patients were studied. Healthcare utilization was measured via length of hospital stay (LOS). Of 262,924 patients, 18% were Black. Following adjustment for confounders, major foot amputations decreased among Whites (1.5% in 2003 to 1.1% in 2014) and Blacks (2.1% in 2003 to 0.9% in 2014). On pooled analysis, Black patients had higher adjusted odds of major foot amputations in 2003–2004 [aOR 1.7; (1.16–2.57), p<0.01]. Disparities in major foot amputations disappeared in 2013–2014 [aOR: 0.92 (0.58–1.44), p = 0.70]. Black patients had declining but persistently longer LOS (adjusted mean difference (aMD): 1.1 days (0.52–1.6) p<0.01 in 2003–2004 and 0.46 days (0.18–0.73) p<0.01 in 2013–2014). The main limitation of the study was that the NIS uses ICD-9 and ICD-10 CM codes, and hence prone to incorrect or missing codes. Conclusions Major foot amputations declined among Black and White patients hospitalized with Diabetic foot complications between 2003 and 2014. The observed difference for amputations in 2003–2004 was absent by 2013–2014. Future research to determine specific contributors for this reduction in health disparities is needed for ongoing improvements and sustainability.

Abstract
Background: Approximately 2-4% of individuals worldwide with diabetes mellitus have foot ulcers. This study aims to assess the factors affecting the outcomes of severe foot ulcers in diabetic individuals. Methods: An analytical prospective cohort study was conducted from March 1st, 2015, to March 1st, 2017. A total of 34 individuals was selected. The study included patients with foot ulcers below the ankle who were at risk of amputation. All tests used a <5% level of significance and confidence interval of 95%. A Pearson's chi-squared test and binary multiple regression were performed to assess the factors related to healing. Results: Only 11.7% of the individuals required amputation; ulcers classified as 2/B according to the University of Texas Diabetic Foot Ulcer Classification System healed before the 1/B ulcers. Neuropathic ulcers were the most prevalent (58.8%); 61.8% healed after 1 year. Most of the individuals were overweight, 47.1% had reduced glomerular filtration rates, and 78.8% had glycated hemoglobin >7%. Body mass index and osteomyelitis were the two significant variables in logistic regression. Conclusions: In this study, osteomyelitis was the main complication related to the risk of amputation, and elevated body mass index and osteomyelitis were the significant factors that induced a slower healing time.

Abstract
AIMS Diabetic foot syndrome (DFS) increases the risk for atherosclerotic cardiovascular disease (ASCVD), chronic kidney disease (CKD), or mortality. The present study aims at ascertaining whether such DFS-related excess risk differs between genders, retrospectively investigating a population with diabetes from Tuscany, Italy, followed-up for 6 years (2011-2016). METHODS People with diabetes living in Tuscany on January 1st 2011 identified by administrative databases, were divided by baseline history of prior DFS hospitalizations, stratified by presence/absence of peripheral vascular disease and evaluating, by Cox regression analysis, whether adjusted DFS-related excess risk of incident ASCVD, CKD or mortality differed between genders. RESULTS In an overall population of 165,650 subjects with diabetes (81,829M/83,821F), basal prevalence of DFS was twice higher among males, who were moreover at a significantly greater risk of all considered outcomes along the 6-year period. On the contrary, baseline DFS significantly increased the hospitalization risk for ASCVD, CKD and mortality equally or at a slightly greater extent in females, while the risk for stroke was significantly associated with DFS only among females (HR: 1.622 (1.314-1.980); p = 0.0001 vs. HR: 1.132 (0.955-1.332); p = NS). This finding was even reinforced in non-vascular DFS, which was associated with a significant raised risk for stroke, heart failure or mortality exclusively in females. CONCLUSIONS In this population, DFS prevalence and overall risk for ASCVD, CKD or mortality were significantly higher among males. Baseline co-presence of DFS, however, conferred a similar adjusted risk for all these outcomes between genders, and in case of non-vascular DFS the risk was significantly increased only among females.

Abstract
Diabetic foot ulcers (DFUs) are a serious complication of diabetes that impact on the patient, their social environment, overall health, and on nursing practice. Nursing scholars have integrated theories on practice to overcome these problems, but a lack of agreement in the available literature acts as a barrier to implementing these in practice. For that reason, using a nursing metaparadigm as a theoretical framework would assist nurses in managing care purposefully and proactively, thus possibly improving outcomes. There has been little discussion about the nursing metaparadigm in relation to DFU care. This article aims to identify why Fawcett's theory of the nursing metaparadigm is important as a fundamental part of DFU care. Understanding this will help to elucidate the phenomenon of DFUs. Moreover, identifying the elements of the DFU care framework is essential to improve reflective practice and intervention. This article discusses the concept of the nursing metaparadigm and its implications for practice in the care of patients with DFUs.

Abstract
Randomized, cross-sectional, and prospective studies have demonstrated that microvascular complications in patients with diabetes are not only the cause of blindness, renal failure and non-traumatic amputations, but also powerful predictors of cardiovascular complications. Beside the metabolic theory, the pathophysiology of diabetic microvascular complications is determined by the interaction among several factors, including epigenetic modifications and the reduced release of progenitor cells by the bone marrow, that contribute simultaneously to damage and impaired vascular protection against hyperglycemia. Identifying and preventing microvascular complications has the significant potential to reduce major adverse cardiovascular events. For these reasons, there may no longer be a rational to consider microangiopathy and macroangiopathy as entirely separate entities, but they should most likely be viewed as a continuum of the widespread vascular damage determined by diabetes mellitus.

Abstract
OBJECTIVE Effective diabetes self-management can prevent long-term health complications but is often complex and difficult to achieve. Health care professionals' support for patients' autonomy (autonomy support) in managing their diabetes contributes to better diabetes self-care and glycemic control. Most adults with diabetes also receive self-management support from informal health supporters. Yet, the role of autonomy support from these informal health supporters has not been explored. We examined patients' perceived autonomy support from their main health supporter (family member or friend) in relation to their diabetes distress, self-efficacy, self-monitoring of blood glucose (SMBG), medication adherence, and hemoglobin A1c (HbA1c). METHOD Three hundred twenty-six veterans with Type 2 diabetes at high risk for complications, who identified a main health supporter, were surveyed using self-report measures of social support, diabetes distress, self-efficacy, and self-care. HbA1c and prescription fill data were extracted from VA electronic records for the 12-months before and after the survey. Linear regression and linear mixed models examined the associations of autonomy support with diabetes distress, self-efficacy, SMBG, medication adherence, and glycemic control, controlling for participant-supporter relationship characteristics and patient-factors. RESULTS In adjusted models, greater autonomy support was associated with lower diabetes distress (B = -.323, SE = .098, p = .001), greater self-efficacy (B = .819, SE = .148, p < .001), more frequent SMBG (B = .297, SE = .082, p < .001), and better subsequent 12-month glycemic control (B = .257, SE = .085, p = .003) but not with medication adherence (B = .001, SE = .020, p = .994). CONCLUSIONS Autonomy support from main health supporters is significantly associated better diabetes related attitudes, self-care, and glycemic control after adjusting for relationship and patient characteristics.

Abstract
BACKGROUND Diabetic foot ulcers (DFU) are a common problem in longstanding diabetes. However, mortality outcomes in Australian patients with DFU are still unclear. METHODS All patients with DFU presenting for the first time to the Multi-Disciplinary Foot Clinic (MDFC) at Royal Darwin Hospital, Northern Territory Australia, between January 2003 and June 2015 were included in this study. These patients were followed until 2017, or death. Individual patient data was extracted from hospital and primary care information systems. Kaplan-Meier survival curves were developed. The association between various risk factors and mortality was analysed using Cox regression. RESULTS In total 666 subjects were screened, and 513 were included in the final analysis. Of these subjects, 247 were Indigenous and 266 were non-Indigenous. The median follow-up period was 5.8 years (IQR, 3.1-9.8). The mean age at inclusion was 59.9 ± 12.3 years and 62.8% were males. The majority (93.6%) had type 2 diabetes and the median diabetes duration was 7 years (IQR, 3-12). There were 199 deaths, with a 5-year-mortality rate of 24.6%, and a 10-year-mortality rate of 45.4%. The mean age at death was 64.6 ± 11.8 years. In a multivariate analysis, the following variables were associated with mortality (adjusted HR, 95% CI): age 1.04 (1.02-1.05, P < 0.001); chronic kidney disease 1.22 (1.11-1.33, P < 0.001), and plasma albumin 0.96 (0.94-0.99, P < 0.05). The most common causes of death were chronic kidney disease (24.6%), cardiovascular events (19.6%), sepsis (15.6%), respiratory failure (10.0%), malignancy (9.5%) and multi-organ failure (5.0%). CONCLUSION Patients with DFU have high mortality. Age, chronic kidney disease, and low albumin levels increase the risk of mortality. Strategies should focus on ulcer prevention and aggressive risk factor reduction.

Abstract
BACKGROUND Diabetic foot ulcer care demonstrates a beneficial approach to overcoming problems in patients with diabetes. This approach is frequently given but is not always successfully implemented due to its fragmentation amid healthcare providers. What's more, there are a number of different understandings, interchangeable languages and an absence of uniformity overlapping terminologies of meaning for diabetic foot ulcer care. Therefore, analysing the concept of diabetic foot ulcer care is important to provide a wider nursing knowledge, synthesise a greater theoretical model and drive more effective care of diabetic foot ulcer. OBJECTIVE This article aimed to analyse how the concept of diabetic foot ulcer care is clearly defined in the relevant evidence as it has several implications in nursing practice. METHOD Walker and Avant's (1995) method of concept analysis was systematically used in this study. FINDINGS Three critical attributes of diabetic foot ulcer care were determined consisting of assessment, intervention and evaluation. Constructed cases are also presented to differentiate the concept of diabetic foot ulcer care from other concepts. This concept analysis results in the critical attributes of diabetic foot ulcer care, defines an operational definition and describes common goals that improve clarity, consistency and understanding of the concept amid healthcare professionals along with researchers. CONCLUSION Effective implementation of the concept of DFU care into clinical nursing practice may undoubtedly improve patient outcomes and prevent the complexities of DFU in the years to come. Future research needs to be developed for evaluating the current use of this concept.

Abstract
The aim of this study was to evaluate the effect of cytoflavin inclusion in therapy regimens of patients with diabetic foot syndrome and medicalcinosis on the microcirculation of the lower limb blood vessels. For this purpose, 64 patients with type II diabetes mellitus (subcompensated form), diabetic foot syndrome and signs of medicalcinosis foot blood vessels of various severity were examined. All patients were divided into 2 groups depending on the therapy scheme: patients of group I (33 people) received insulin, antibiotics, disaggregants, statins, anti-inflammatory drugs, painkillers, detoxification therapy. Patients of group II (31 patients) in addition to the main therapy received cytoflavin according to the scheme: 10 ml per 0.9 ml NaCl 200 ml intravenously, drip at a rate of 60 cap/min, 10 days course, then 2 tablets 2 times a day for 1 month. The severity of the microangiopathy of the lower extremities was assessed considering transcutaneous oximetry data in dynamics (before treatment, on the 10th and 40th day of therapy) gained using TCM-2 device (RADIOMETER, Denmark) with has heating oxygen electrode type Clarc. Before the treatment subcompensated level of metabolic disorders corresponding to the II degree of microcirculatory disorders was registered in all patients. Against the backdrop of cytoflavin inclusion in the complex therapy, there was an improvement in the metabolic rate (up to compensated) with a decrease in the degree of microcirculation disorders up to I degree. Positive dynamics of metabolic disorders significantly reduced frequency and extent of surgical interventions. The results obtained suggest that cytoflavin should be included in the treatment regimens of patients with this pathology.

[PMID: 30098549 DOI: 10.1016/j.biopha.2018.07.157] [Citation(s) in RCA: 199] [Impact Index Per Article: 33.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2018] [Revised: 07/15/2018] [Accepted: 07/31/2018] [Indexed: 02/09/2023] Open
Abstract
Chronic exposure of glucose rich environment creates several physiological and pathophysiological changes. There are several pathways by which hyperglycemia exacerbate its toxic effect on cells, tissues and organ systems. Hyperglycemia can induce oxidative stress, upsurge polyol pathway, activate protein kinase C (PKC), enhance hexosamine biosynthetic pathway (HBP), promote the formation of advanced glycation end-products (AGEs) and finally alters gene expressions. Prolonged hyperglycemic condition leads to severe diabetic condition by damaging the pancreatic β-cell and inducing insulin resistance. Numerous complications have been associated with diabetes, thus it has become a major health issue in the 21st century and has received serious attention. Dysregulation in the cardiovascular and reproductive systems along with nephropathy, retinopathy, neuropathy, diabetic foot ulcer may arise in the advanced stages of diabetes. High glucose level also encourages proliferation of cancer cells, development of osteoarthritis and potentiates a suitable environment for infections. This review culminates how elevated glucose level carries out its toxicity in cells, metabolic distortion along with organ dysfunction and elucidates the complications associated with chronic hyperglycemia.

Abstract
Objective: The study aims to investigate the potential role of C2437T (Met493Thr) single nucleotide polymorphism (SNP) of the heat shock protein (HSP) 70 in diabetic foot ulcer patients. Methods: In this prospective cohort study, SNP of the HSP70 hom gene, also called HSPA1L, was studied among diabetic patients with an ulcer (Group A: n = 50), diabetic patients without an ulcer (Group B: n = 50), and healthy subjects (Group C: n = 50). Results: There was a higher frequency of T/T genotype in group A (76%) as compared to group B (44%) and group C (14%). Moreover, the frequency of T allele was 7.3% in group A, 5.5% in group B, and 3.9% in group C. C allele frequency was 2.6%, 4.4%, and 6.1% in group A, group B, and group C, respectively. In group A, the odds ratio and risk ratio were 19-fold and 5-fold, respectively, for the HSP70 hom T/T homozygous gene compared to B (OR 19.45; RR 5.42; X2 38.8, p < 0.0001). Moreover, 4-fold and 1.75-fold ratios have been compared with group C (OR 4.03; RR 1.72; X2 10.6, p < 0.001). No significant difference in genotype was observed in group B and group C. Conclusions: There is a significant and positive association of hspHSP70 hom polymorphism restricted to T allele in homozygous and heterozygous states among diabetic foot ulcer (DFU) patients.

Abstract
Background Thermal imaging is a useful modality for identifying preulcerative lesions (“hot spots”) in diabetic foot patients. Despite its recognised potential, at present, there is no readily available instrument for routine podiatric assessment of patients at risk. To address this need, a novel thermal imaging system was recently developed. This paper reports the reliability of this device for temperature assessment of healthy feet. Methods Plantar skin foot temperatures were measured with the novel thermal imaging device (Diabetic Foot Ulcer Prevention System (DFUPS), constructed by Photometrix Imaging Ltd) and also with a hand-held infrared spot thermometer (Thermofocus® 01500A3, Tecnimed, Italy) after 20 min of barefoot resting with legs supported and extended in 105 subjects (52 males and 53 females; age range 18 to 69 years) as part of a multicentre clinical trial. The temperature differences between the right and left foot at five regions of interest (ROIs), including 1st and 4th toes, 1st, 3rd and 5th metatarsal heads were calculated. The intra-instrument agreement (three repeated measures) and the inter-instrument agreement (hand-held thermometer and thermal imaging device) were quantified using intra-class correlation coefficients (ICCs) and the 95% confidence intervals (CI). Results Both devices showed almost perfect agreement in replication by instrument. The intra-instrument ICCs for the thermal imaging device at all five ROIs ranged from 0.95 to 0.97 and the intra-instrument ICCs for the hand-held-thermometer ranged from 0.94 to 0.97. There was substantial to perfect inter-instrument agreement between the hand-held thermometer and the thermal imaging device and the ICCs at all five ROIs ranged between 0.94 and 0.97. Conclusions This study reports the performance of a novel thermal imaging device in the assessment of foot temperatures in healthy volunteers in comparison with a hand-held infrared thermometer. The newly developed thermal imaging device showed very good agreement in repeated temperature assessments at defined ROIs as well as substantial to perfect agreement in temperature assessment with the hand-held infrared thermometer. In addition to the reported non-inferior performance in temperature assessment, the thermal imaging device holds the potential to provide an instantaneous thermal image of all sites of the feet (plantar, dorsal, lateral and medial views).

Abstract
BACKGROUND Diabetic foot is one of the most common complications of diabetes. It has the potential risk of pathologic consequences including infection, ulceration and amputation, but a growing body of evidence suggests that physical activity and exercise may improve diabetic foot outcomes. OBJECTIVE To analyze de effects of exercise and physical activity interventions on diabetic foot outcomes. METHODS A comprehensive and systematic search was conducted according to PRISMA recommendations. Only controlled clinical trials with patients with diabetes were included. RESULTS Six studies, involving 418 patients with diabetes, were included. Two studies used only aerobic exercise; two studies combined aerobic, resistance and balance exercise; and two studies combined aerobic and balance exercise by Thai Chin Chuan methods. Physical activity and exercise significantly improved nerve velocity conduction, peripheral sensory function and foot peak pressure distribution. Moreover, the ulcers incidence rate per year was lower in the intervention groups, compared with the controls [0.02 vs. 0.12]. CONCLUSION This review suggests evidence that physical activity and exercise is an effective non-pharmacological intervention to improve diabetic foot related outcomes. Combined multi-disciplinary treatments are more effective in the prevention of foot complications in patients with diabetes.

Abstract
BACKGROUND Although Diabetes mellitus is a major public health problem in the Middle East and North Africa (MENA) region with high rates of diabetic foot complications, there are only limited data concerning mortality among such a high risk group. Therefore, the main aim of the current study was to assess all-cause mortality and its related predictors among diabetic patients with and without diabetic foot complications. METHODS Using data from the Saudi National Diabetes Registry (SNDR), a total of 840 patients with type 1 or type 2 diabetes aged ≥25 years with current or past history of diabetic foot ulcer (DFU) or diabetes related lower extremity amputation (LEA) were recruited in 2007 from active patients' files and followed up to 2013. These patients were compared with an equal number of age and gender matched diabetic patients without foot complication recruited at the same period. All patients were subjected to living status verification at 31st December 2013. RESULTS The all-cause mortality rate among patients with DFU was 42.54 per 1000 person-years and among LEA patients was 86.80 per 1000 person-years among LEA patients for a total of 2280 and 1129 person-years of follow up respectively. The standardized mortality ratio (SMR) (95% CI) was 4.39 (3.55-5.23) and 7.21 (5.70-8.72) for cases with foot ulcer and LEA respectively. The percentage of deceased patients increased by almost twofold (18.5%) among patients with diabetic foot ulcer and more than threefold (32.2%) among patients with LEA compared with patients without diabetic foot complications (10.7%). The worst survival was among patients with LEA at 0.679 and the presence of diabetic nephropathy was the only significant independent risk factor for all-cause mortality among patients with diabetic foot complications. On the other hand, obese patients have demonstrated significantly reduced all-cause mortality rate. CONCLUSIONS Diabetic patients with diabetic foot complications have an excess mortality rate when compared with diabetic counterparts without foot complications and the general population. Early interventions to prevent foot ulceration and consequent LEA as well as all the measurements for reducing the prevalence of microvascular and macrovascular complications should be considered.

Abstract
AIMS Diagnosis of vascular involvement in diabetic foot ulceration (DFU) remains challenging. We conducted a proof of concept study to investigate the feasibility of microwave radiometry (MWR) thermometry for non-invasive differential diagnosis of critical limb ischemia (CLI) in subjects with DFU. METHODS This prospective, multi-center, study included 80 participants, divided into four groups (group N: normal control subjects; group DN: participants with diabetes and verified neuropathic ulcers without vascular involvement; group DC: participants with diabetes and CLI and group NDC: participants with CLI without diabetes). Vascular disease was confirmed with angiography. All patients underwent MWR (RTM-01-RES:University of Bolton, UK) to record mean tissue temperatures at various pre-determined foot sites. Comparisons of temperature measurements between study groups were performed using one-way ANOVA and Dunn tests. ROC analysis was performed to determine sensitivity, specificity and cut-off value of MWR for CLI diagnosis. RESULTS Temperatures recorded in vicinity to the foot ulcers of participants with diabetes and CLI were similar to those with CLI without diabetes, but significantly lower than in subjects with neuropathic ulcers without vascular involvement and normal controls (group DC:29.30°C±1.89 vs. group NDC:29.18°C±1.78vs. group N:33.01°C±0.45 vs. group DN:33.39°C±1.37;P<.0001). According to ROC analysis, cut-off temperature value to diagnose CLI was <31.8°C (area under the curve: 0.984; 95% CI: 0.965-1.005;P<.001), with a sensitivity of 100.0% (95%CI: 90.26-100.0) and specificity of 88.37% (95% CI: 74.92-96.11). CONCLUSIONS Tissue temperatures in vicinity to ulcers were significantly lower in participants with CLI, with or without diabetes, compared to non-ischemic controls. MWR could be used for differential diagnosis of arterial ischemia in subjects with DFU.

Abstract
BACKGROUND AND OBJECTIVE This study reviews the clinical characteristics of patients with diabetic foot ulcer treated in a Multidisciplinary Diabetic Foot Unit (MDFU) and analyzes the mortality and factors associated with its survival. MATERIAL AND METHODS Data from all patients who attended the MDFU for the first time for a diabetic foot ulcer during the 2008-2014 period were analized. The patients were followed until their death or until June 30, 2016, for up to 8 years. RESULTS A total of 345 patients were included, with a median age (P25-P75) of 71 (61.5-80) years, and 321 (93%) had type 2 diabetes. They were characterized as patients with inadequate glycemic control, 48% had HbA1c ≥ 8% and high prevalence of chronic complications: 60.2% retinopathy, 43.8% nephropathy and 47.2% ischemic heart disease and/or cerebrovascular disease. A total of 126 (36.5%) patients died and 69 (54.8%) were due to cardiovascular disease. Survival measured by Kaplan-Meier declined over time to 69, 60 and 45% at 3, 5 and 7 years respectively. Cox's multivariate regression analysis showed the following variables associated with mortality, HR (95% CI): age 1.08 (1.05-1.11); previous amputation 2.24 (1.34-3.73); active smoking 2.10 (1.12-3.97); cerebrovascular disease 1.75 (1.05-2.92); renal dysfunction 1.65 (1.04-2.61) and ischemic heart disease 1.60 (1.01-2.51). CONCLUSIONS Patients with diabetic foot ulcer are characterized by high morbidity and mortality, with cardiovascular disease being the most frequent cause of death. It is necessary to pay more attention to this risk group, tailoring objectives and treatments to their situation and life expectancy.

Abstract
Background The diagnosis of type 2 diabetes mellitus (T2DM) carries with it a number of changes to the patient’s lifestyle. A healthy lifestyle, health and preventive behaviors, as well as healthy nutrition habits play a key role in treating T2DM as well as limiting its complications. Materials and methods The aim of this study was the analysis of the correlation of T2DM patients’ health behaviors and their influence on the patients’ quality of life. The study was performed on a group of 50 patients from the Kuyavian–Pomeranian Voivodeship. In this study, the Health Behavior Inventory and the Satisfaction with Life Scale were used. The results were statistically analyzed. The study was approved by the ethics committee. Results The intensity of severity of health behavior and satisfaction with life of T2DM patients depends on the gender of the patient (P<0.05). The analysis of the patients’ behaviors in four categories, proper eating habits (consuming vegetables, fruit, whole meal bread), health practices (daily physical activity, recreation, sleeping habits), preventive behaviors (including keeping to health recommendations), and positive mental attitude, showed substantial correlation of the Health Behavior Inventory and the Satisfaction with Life Scale (P<0.05). Conclusion The categorization of the prohealth behaviors shown by diabetics allowed us to measure the connection between the individual categories of satisfaction with life. Males with T2DM showed a higher satisfaction with life score than females with the same diagnosis. The analysis showed that patients with a higher intensity of health behaviors also had superior health behaviors. The resulting correlations prove a notable relationship.

Hunt SD, Elg F. Clinical effectiveness of hemoglobin spray (Granulox ®) as adjunctive therapy in the treatment of chronic diabetic foot ulcers. Diabet Foot Ankle 2016; 7:33101. [PMID: 27829487 PMCID: PMC5102129 DOI: 10.3402/dfa.v7.33101] [Citation(s) in RCA: 36] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2016] [Accepted: 10/08/2016] [Indexed: 05/10/2023]
Abstract
INTRODUCTION Hemoglobin spray (Granulox®) comprises purified hemoglobin and is a novel approach for increasing oxygen availability in the wound bed in diabetic foot ulcer patients. Its mode of action is to bind oxygen from the atmosphere and diffuse it into the wound bed to accelerate wound healing in slow-healing wounds. PATIENTS AND METHODS Wound healing outcomes, that is, wound size, pain, percentage of slough, and exudate levels, were compared retrospectively to a similar cohort of patients treated over the same period the previous year. The same inclusion and exclusion criteria applied to both groups. RESULTS All 20 (100%) hemoglobin spray-treated patients and 15 (75%) control patients experienced some wound healing by week 4, with 5 (25%) and 1 (5%), respectively, achieving complete wound closure. At week 4, mean wound size reduction was 63% in the hemoglobin spray group versus 26% for controls, increasing to 95% reduction at week 28 in the hemoglobin spray group versus 63% for controls (p<0.05 at all timepoints). Hemoglobin spray was associated with substantially lower pain scores using a 10-cm visual analogue scale, with 19/19 patients (100%) being pain-free from week 12 onwards, compared to 6/18 patients (33%) in the control group. At week 28, 2/18 patients (11%) in the control group still had pain. Both groups had similar baseline slough levels, but hemoglobin spray-treated wounds had slough completely eliminated after 4 weeks versus 10% mean reduction in the control group (p<0.001). Hemoglobin spray was associated with markedly reduced exudate levels; within 4 weeks, no patients had high exudate levels in the hemoglobin spray group versus 5 in the control group. CONCLUSION Standard wound care plus hemoglobin spray results in improvements in wound closure, wound size reduction, pain, slough, and exudate levels compared to control patients for chronic diabetic foot ulcer treatment.
