RESUMO

INTRODUCTION: The effectiveness of the treatment has long been significant in diabetes and its complications, especially in developing countries. Prolonged hospitalization and repeated surgery should be avoided due to clinical and economic reasons. Wound breakdowns or necrosis can occur after amputation procedures, and subsequently will require reamputation. This study analyzed susceptibility factors in diabetic foot patients undergoing prior high toe amputation that are thought to be related to early reamputation. METHODS: We performed a retrospective analysis in 107 patients that have undergone amputation for great toe gangrene, during May 2014-April 2019. Demographic data, clinical features, laboratory results and treatment modality, were documented and statistically analyzed by simple and multiple logistic regression methods. RESULTS: Of all 107 patients, 17 patients had to undergo early reamputation. Limited dorsiflexion, level of amputation, and sepsis condition is shown to be significantly associated with first amputation. Multiple logistic regression analysis confirmed a significant association of early reamputation with amputation or disarticulation at the level of the metatarsophalangeal joint. CONCLUSION: While limited ankle dorsiflexion and sepsis conditions need to be addressed comprehensively, from the surgical options point of view, we suggest ray amputation to be preferred over metatarsophalangeal joint disarticulation to prevent early reamputation.

RESUMO

The article deals with the use of a genetically engineered drug for stimulation of angiogenesis as a component of combined treatment of complications of ischaemic form of diabetic foot syndrome, showing comparative results of using therapeutic angiogenesis in patients in whom it was impossible to perform operative revascularization of the affected extremity, also providing a detailed description of the methodology of combined treatment of pyonecrotic complications of diabetic foot syndrome. The study included a total of 62 patients with pyonecrotic complications of Wagner grade III-IV diabetic foot syndrome. The patients were divided into two groups. Group One patients after minor amputation on the foot were assigned to receive conventional basic therapy and topical treatment of the foot wound with antiseptics and modern dressings. Group Two patients, besides basic therapy, additionally received combined treatment which was carried out in two stages and included urokinase, sulodexide, and a venotonic agent. Local treatment of the foot wound was performed with the help of two-stage vacuum therapy. Both groups were further subdivided into subgroups A and B. The patients in subgroups B of both groups in order to prevent progression of limb ischaemia were additionally given Neovasculgen, a genetically engineered drug for stimulation of angiogenesis. The patients of subgroups A of both groups did not receive this drug. The immediate results were assessed on the 1st, 7th and 14th days of treatment by the dynamics of changes in subjective symptoms, cytograms of the wound surface, level of partial pressure of oxygen in capillary blood of foot tissues, and the necessity to perform repeated necrectomy. The remote results were evaluated by the dynamics of changes in the pain-free walking distance, maximum distance walked, ankle-brachial index, linear velocity of blood flow through tibial arteries and partial pressure of oxygen in capillary blood of the affected limb at the 6th, 12th and 36th months after the performed treatment, as well as by the limb salvage and patients' survival during 3 years.

RESUMO

A person with a diabetic foot ulcer (DFU) requires multidisciplinary care, including moist wound healing, consistent offloading of insensate areas, glycemic control, and adequate circulation. This is especially important during the COVID-19 pandemic, as patients with diabetes are at a higher risk of mortality.1 Reviewed in a 2018 installment of Evidence Corner,2 a double-blind, randomized clinical trial (RCT) reported that topical oxygen continuously diffused to DFU tissue resulted in nonhealing DFUs healing more than 20 days faster than those that were similarly treated with standard therapy and a sham device.3 More than twice the DFUs closed in patients receiving continuously diffused topical oxygen in comparison with the sham arm completely healed in 12 weeks (P = .02). It has been hypothesized that intervals of hyperbaric oxygen (HBO)-breathing 100% oxygen at atmosphere absolute (ATA) greater than the 1.0 normal at sea level-may similarly improve lower extremity ulcer healing outcomes. This month's Evidence Corner summarizes 2 studies regarding patients receiving HBO. The first study focused on patients with a DFU on a non-ischemic limb.4 The second studied the effects of HBO on lower extremity ulcers on ischemic limbs in patients with or without diabetes mellitus (DM).5 Read on to discover how informative and beneficial each of these studies can be in furthering best practice as well as which patients may experience improved lower limb ulcer healing in response to interventions that increase tissue oxygenation.

RESUMO

Despite a benign appearance, any foot injury occurring in a patient with diabetes requires multidisciplinary management if dreaded complications such as amputation are to be avoided. From a pathophysiological point of view, foot ulcer generally results from the combination of lower extremity neuropathy, mechanical overload, immunopathy and vascular insufficiency. The treatment associates in all cases an offloading and one or more debridements. Depending on the grade of the ulcer, adjuvant treatments, such as antibiotic therapy, revascularization, and hyperbaric oxygen therapy may be indicated.

RESUMO

Objective: To review the research progress of adrenergic ß-antagonists on wounds and diabetic chronic cutaneous ulcers healing in recent years, and to investigate its application prospect in diabetic foot ulcer (DFU). Methods: The latest literature about the role of adrenergic ß-antagonists in wounds and diabetic chronic cutaneous ulcers healing was extensively reviewed, and the mechanisms of adrenergic ß-antagonists for wounds and its potential benefit for DFU were analyzed thoroughly. Results: The adrenergic ß-antagonists can accelerate the wound healing. The possible mechanisms include accelerating re-epithelialization, promoting angiogenesis, improving neuropathy, and regulating inflammation and growth factors, etc. At present clinical research data showed that the adrenergic ß-antagonists may be an adjuvant treatment for diabetic chronic cutaneous ulcers. Conclusion: Adrenergic ß-antagonists maybe promote the healing of wounds and diabetic chronic cutaneous ulcers. However, more long-term follow-up and high-quality randomized control studies are needed to further verify their efficacy and safety for DFU.

RESUMO

Background: Diabetic foot ulcer is an intractable complication of diabetes, characterized by the disturbed inflammatory and proliferative phases of wound healing. Sesamol, a phenolic compound, has been known for its powerful antioxidant, anti-inflammatory, anti-hyperglycaemic and wound healing properties. The aim of the present study was to develop a sesamol nano formulation and to study its effect on the various phases of the wound healing process in diabetic foot condition. Methods: Sesamol-PLGA (SM-PLGA) nanosuspension was developed  using nanoprecipitation method. TEM, in vitro drug release assay and in vivo pharmacokinetic studies were performed for the optimised formulation. Diabetic foot ulcer (DFU) in high fat diet (HFD)-fed streptozotocin-induced type-II diabetic animal model was used to assess the SM-PLGA nanosuspension efficacy. SM-PLGA nanosuspension was administered by oral route. TNF-α levels were estimated using ELISA and Western blot analysis was performed to assess the effect on the expression of HSP-27, ERK, PDGF-B and VEGF in wound tissue. Wound re-epithelization, fibroblast migration, collagen deposition and inflammatory cell infiltration were assessed by H&E and Masson's trichrome staining. Effect on angiogenesis was assessed by CD-31 IHC staining in wound sections. Results: The optimized SM-PLGA nanosuspension had an average particle size of <300 nm, PDI<0.200 with spherical shaped particles. Approximately 80% of the drug was released over a period of 60 h in in vitro assay. Half-life of the formulation was found to be 13.947 ± 0.596 h. SM-PLGA nanosuspension treatment decreased TNF-α levels in wound tissue and accelerated the collagen deposition. Whereas, HSP-27, ERK, PDGF-B and VEGF expression increased and improved new blood vessels' development. Rapid re-epithelization, fibroblast migration, collagen deposition and reduced inflammatory cell infiltration at the wound site were also observed. Conclusion: Results indicate that sesamol-PLGA nanosuspension significantly promotes the acceleration of wound healing in diabetic foot ulcers by restoring the altered wound healing process in diabetic condition.

RESUMO

OBJECTIVES: To assess knowledge about diabetic foot, care measures, and the importance attached to serial treatment in a group of high-risk diabetic foot patients. METHODS: This is a cross-sectional study, carried out in a tertiary hospital, with 25 patients undergoing serial treatment for diabetic foot. The tabulation of the data occurred through the use of three methodological figures: core idea, key expressions, and the collective subject discourse. RESULTS: It became evident that even among high-risk patients with diabetic foot, there is no complete knowledge about the definition of the disease. Despite this, all participants reported practicing daily care measures, including frequent inspection of the feet, food care, and attention to footwear. Regarding the importance of serial treatment, there was unanimous recognition of the relevance of this practice, which improves self-care discipline, optimizes the understanding of the disease, and helps to prevent progression. CONCLUSIONS: Authentic speeches in the context of a pathology of considerable prevalence manifested, in an unprecedented way, with conceptions about its definition, care measures, and importance of serial treatment in a high-risk group.

RESUMO

Objective: To explore the vascular conditions and the necessity of vascular reconstruction in the treatment of chronic ischemic diseases of lower extremities with tibial transverse transport (TTT) from the perspective of vascular surgery. Methods: A clinical data of 59 patients with chronic ischemic disease of lower extremities treated by TTT between February 2014 and July 2019 were analyzed retrospectively. Among them, there were 41 patients with diabetic foot (DF), including Wagner grade 3-4, Texas grade 2-3, and stage B-D lesions; the disease duration ranged from 0.7 to 2.4 years, with an average of 1.5 years, and 5 cases complicated with arteriosclerosis obliteran (ASO). There were 14 patients with ASO (Fontaine stage Ⅳ and Rutherford stage Ⅲ-Ⅳ) with an average disease duration of 10.8 months (range, 1.5-23.4 months). There were 4 patients with thromboangiitis obliteran (TAO) with an average disease duration of 12.3 months (range, 2.1-18.2 months), and the clinical stages were all in the third stage. In 18 patients that ankle brachial index (ABI) of anterior or posterior tibial artery was less than 0.6 before operation, or the blood flow of the three branches of inferior anterior tibial artery did not reach the ankle by imaging examination, vascular reconstruction was performed before TTT (5 cases of DF combined with ASO, 12 of ASO, 1 of TAO). After operation, the effectiveness was evaluated by ulcer wound healing, skin temperature, pain visual analogue scale (VAS) score, ABI, and CT angiography (CTA) examination. Results: The patients with DF were followed up 8-16 months (mean, 12.2 months); the ulcer wounds healed with a healing time of 5.1-9.2 weeks (mean, 6.8 weeks); CTA examination showed that the branches of inferior anterior tibial artery were opened in 5 patients after revascularization; and the tibial osteotomy healed for 5-14 weeks (mean, 8.3 weeks). The patients with ASO were followed up 13-25 months (mean, 16.8 months); the ulcer wounds healed with a healing time of 6.2-9.7 weeks (mean, 7.4 weeks). CTA examination showed that the branches of inferior anterior tibial artery were opened in 12 patients after revascularization; all tibial osteotomy healed, and the healing time was 4.5-14.4 weeks (mean, 10.2 weeks). The patients with TAO were followed up 12-23 months with an average of 12.3 months, and toe/limb amputation was performed after ineffective treatment. The patients were divided into two groups according to whether they were combined with revascularization or not. The ABI, VAS score, and skin temperature in the combined revascularization group significantly improved at 6 months after operation ( P<0.05); while there was no significant difference in ABI at 6 months after operation in the TTT group ( P>0.05), but the skin temperature and VAS scores significantly improved when compared with those before operation ( P<0.05). Conclusion: The ABI of anterior or posterior tibial artery is more than 0.6, radiological examination shows that at least one of the three branches of inferior anterior tibial artery leads to ankle artery, which is a prerequisite for successful TTT in the treatment of chronic ischemic disease of lower extremities. DF is the indication of TTT. ASO can choose TTT, and TAO should use this technique cautiously.

RESUMO

Objective: To investigate the clinical effects of skin-stretching device (hereinafter referred to as stretcher) combined with vacuum sealing drainage (VSD) in repairing diabetic foot wounds. Methods: From March 2016 to January 2020, 25 patients with diabetic foot wounds were admitted to the First Affiliated Hospital of Air Force Medical University, including 18 males and 7 females, with age of 40 to 70 years. After debridement, intermittent VSD was performed for 3 to 10 days, with negative pressure value of -10.67 kPa. Then, the wound area was 5.0 cm×3.0 cm to 10.0 cm×7.0 cm. After infection control and detumescence, the wound was treated with stretcher for 3 to 5 days. The wound area after stretching ranged from 5.0 cm×0.3 cm to 10.0 cm×0.5 cm. The wound was closed with full-thickness suture. Two weeks after the suturing operation, the healing grade of the foot wound of patients was observed, and the serious complications such as recurrence of ulcer wound and gangrene on the foot, scar condition of the wound were observed during follow-up. Results: Two weeks after the suturing operation, the wounds of 23 patients were healed with grade A. Soft tissue infection ulcer relapsed in 2 patients during the stretch period. After anti-infection, thorough debridement, and VSD, the wounds were healed after another 16 days of stretch treatment. During the follow-up of 3 to 36 months, 23 patients had linear scar left on the stretch wounds, and the skin elasticity, color, sensation was similar to the surrounding normal tissue, and the limb mobility was good, and 2 patients had obvious scar hyperplasia. One patient had recurrence of diabetic foot and serious vascular occlusion and gangrene in the affected limb at follow-up of 10 months, which was treated with amputation of the lower leg. Conclusions: The use of stretcher combined with VSD in treating diabetic foot wound can avoid donor site injury, with healed wound achieving similar appearance to adjacent skin and satisfactory repair effects.

RESUMO

Objective: To investigate the mechanism of maggot debridement therapy (MDT) in promoting wound angiogenesis in patients with diabetic foot ulcer (DFU). Methods: (1) From June 2018 to June 2019, the patients admitted to Nanjing Junxie Hospital who met the inclusion criteria were recruited, including 12 DFU patients given MDT for three days [6 males and 6 females, aged (56±12) years] and 12 acute trauma patients without diabetes mellitus [6 males and 6 females, aged (53±10) years], who were enrolled into DFU group and non-diabetic trauma group respectively. Before and after application of MDT, the wound characteristics of patients in DFU group were observed and the wound tissue samples were taken. The wound tissue in non-diabetic trauma group was taken at patient's first visit before debridement. The expression of angiogenesis marker CD31 in the wound tissue of patients in DFU group was detected by immunohistochemistry before and after application of MDT. Western blotting and real-time fluorescent quantitative reverse transcription polymerase chain reaction (RT-PCR) were used respectively to detect the protein and mRNA expressions of fatty acid synthase (FAS) in wound tissue of patients in DFU group before and after application of MDT and in non-diabetic trauma group before debridement. (2) Human umbilical vein endothelial cells (HUVECs) were cultured in endothelial cell culture medium containing 10% fetal bovine serum. The 3rd to 6th passages of cells in logarithmic growth phase were used in the following experiments. Excretions/secretions (ES) were extracted from 3-day-old sterile Lucilia sericata larvae for subsequent experiments. Three batches of cells were divided into phosphate buffer solution (PBS) control group, high glucose alone group, high glucose+ 5 µg/mL maggot ES group, and high glucose+ 10 µg/mL maggot ES group, which were treated with PBS, glucose in final molarity concentration of 20 mmol/L, glucose in final molarity concentration of 20 mmol/L+ maggot ES in final mass concentration of 5 µg/mL, and glucose in final molarity concentration of 20 mmol/L+ maggot ES in final mass concentration of 10 µg/mL respectively. The total volume of reagents in each group was the same. After 48 hours of culture, Western blotting, real-time fluorescent quantitative RT-PCR and immunofluorescence method were used to detect the protein and mRNA expressions of FAS in each batch of cells and the expression and localization of FAS protein in cells respectively. The number of samples for mRNA expression was 3. (3) Two batches of cells were divided into small interference RNA (siRNA) alone group, siRNA control+ maggot ES group and siRNA-FAS+ maggot ES group, which were transfected with 100 µmol/L (final molarity concentration) insignificant control siRNA, insignificant control siRNA, and siRNA-FAS for 4-6 h respectively, and then they were routinely cultured for 24 h with PBS added, maggot ES in final mass concentration of 10 µg/mL, and maggot ES in final mass concentration of 10 µg/mL respectively. The total volume of reagents in each group was the same. One batch of cells was used for scratch test, the scratch width was observed at 24 hour after scratching to detect the cell migration ability; one batch of cells was subjected to tube forming experiment, and the formation of cell tubules was observed after 24 hours of culture. The number of samples was 3 in scratch test and tube forming experiments. Data were statistically analyzed with t test, one-way analysis of variance, least significant difference test, analysis of variance for repeated measurement, and Bonferroni method. Results: (1) Compared with those before application of MDT, fresh granulation tissue significantly increased and necrotic tissue decreased obviously in wound, and the expression of CD31 significantly increased in wound tissue of patients in DFU group after application of MDT. The expression of FAS protein in wound tissue of patients in DFU group before application of MDT was significantly lower than that in non-diabetic trauma group before debridement, and the expression of FAS protein in wound tissue of patients in DFU group after application of MDT was significantly higher than that before application of MDT. The expression of FAS mRNA in wound tissue of patients in DFU group before application of MDT was 1.00±0.17, which was significantly less than 3.87±1.02 in non-diabetic trauma group before debridement (t=9.808, P<0.01). The expression of FAS mRNA in wound tissue of patients in DFU group after application of MDT was 1.85±0.31, which was significantly higher than that before application of MDT (t=-10.853, P<0.01). (2) After 48 hours of culture, Western blotting detection showed that the expression of FAS protein in cells in high glucose alone group was significantly less than that in PBS control group, and the expressions of FAS protein in cells in high glucose+ 5 µg/mL maggot ES group and high glucose+ 10 µg/mL maggot ES group were significantly higher than the expression in high glucose alone group. Real-time fluorescent quantitative RT-PCR determination showed that the expression of FAS mRNA in cells in high glucose alone group was 0.392±0.073, which was significantly lower than 1.000±0.085 in PBS control group (P<0.01); there was statistically significant difference between the expression of FAS mRNA in cells in high glucose+ 5 µg/mL maggot ES group (0.561±0.047) and that in high glucose+ 10 µg/mL maggot ES group (0.687±0.013) (P<0.05), both of which were significantly higher than the expression in high glucose alone group (P<0.01). The results of immunofluorescence detection showed that FAS protein was mainly located in the cytoplasm of cells in each group, and its expression was similar to that detected by Western blotting. (3) At 24 hour after scratch, the uncured widths of cell scratch in siRNA control+ maggot ES group and siRNA-FAS+ maggot ES group were significantly narrower than the uncured width in siRNA alone control group (P<0.01), and the uncured width of cell scratch in siRNA-FAS+ maggot ES group was significantly wider than that in siRNA control+ maggot ES group (P<0.01). After 24 hours of culture, the numbers of tubules in siRNA+ maggot ES group and siRNA-FAS+ maggot ES group were significantly more than the number in siRNA alone control group (P<0.05 or P<0.01), and the number of tubules in siRNA-FAS+ maggot ES group was obviously less than that in siRNA control+ maggot ES group (P<0.05). Conclusions: MDT up-regulates the expression of FAS through maggot ES, which promotes the activity of vascular endothelial cells, thus promoting the wound angiogenesis in patients with DFU.

RESUMO

The treatment of diabetic ulcer (DU) remains a major clinical challenge due to the complex wound-healing milieu that features chronic wounds, impaired angiogenesis, persistent pain, bacterial infection, and exacerbated inflammation. A strategy that effectively targets all these issues has proven elusive. Herein, we use a smart black phosphorus (BP)-based gel with the characteristics of rapid formation and near-infrared light (NIR) responsiveness to address these problems. The in situ sprayed BP-based gel could act as 1) a temporary, biomimetic "skin" to temporarily shield the tissue from the external environment and accelerate chronic wound healing by promoting the proliferation of endothelial cells, vascularization, and angiogenesis and 2) a drug "reservoir" to store therapeutic BP and pain-relieving lidocaine hydrochloride (Lid). Within several minutes of NIR laser irradiation, the BP-based gel generates local heat to accelerate microcirculatory blood flow, mediate the release of loaded Lid for "on-demand" pain relief, eliminate bacteria, and reduce inflammation. Therefore, our study not only introduces a concept of in situ sprayed, NIR-responsive pain relief gel targeting the challenging wound-healing milieu in diabetes but also provides a proof-of-concept application of BP-based materials in DU treatment.

RESUMO

OBJECTIVE: To assess the improvement in the management of diabetes and its complications based on the evolution of hospitalisation rates for diabetic foot ulcer (DFU) and lower extremity amputation (LEA) in individuals with diabetes in France. METHODS: Data were provided by the French national health insurance general scheme from 2008 to 2014. Hospitalisations for DFU and LEA were extracted from the SNIIRAM/SNDS French medical and administrative database. RESULTS: In 2014, 22,347 hospitalisations for DFU and 8,342 hospitalisations for LEA in patients with diabetes were recorded. Between 2008 and 2014, the standardised rate of hospitalisation for DFU raised from 508 to 701/100,000 patients with diabetes. In the same period, the standardised rate of LEA decreased from 301 to 262/100,000 patients with diabetes. The level of amputation tended to become more distal. The proportion of men (69% versus 73%) and the frequency of revascularization procedures (39% versus 46%) increased. In 2013, the one-year mortality rate was 23% after hospitalisation for DFU and 26% after hospitalisation for LEA. CONCLUSIONS: For the first time in France, the incidence of a serious complication of diabetes, i.e. amputations, has decreased in relation with a marked improvement in hospital management.

RESUMO

Diabetic foot ulcers (DFU) are the most costly and serious complication for patients with Diabetes Mellitus (DM). Among patients with DM, 4% annually and up to one third in their entire lifetime may experience a DFU. The majority of DFU do not heal in a timely fashion and non-healing is associated with complications including skin, soft tissue, bone and systemic infection as well as the need for amputation. While education and advances in standard care for DFU have occurred, more research is critical to identify new and better therapies for patients with DFU. In this review, we examine ongoing clinical trials (through clinicaltrials.gov) on treatments for DFU. Our review focuses on new, upcoming therapies, including topical agents, dressings, engineered tissue, cell therapy, growth factors, devices, and herbal/natural remedies. The preclinical background information for each of these new therapies is also reviewed and discussed.

RESUMO

INTRODUCTION: Diabetes is a chronic-degenerative disease that develops after pancreatic dysfunction. An estimated 422 million people in the world are currently diagnosed with diabetes. One of its most common complications is diabetic foot. It is estimated that about 15% of diabetic patients will have lower extremities ulcers. MATERIAL AND METHODS: It is an observational, descriptive, prospective and cross-sectional study. It aims to know what the initial injuries that triggered an amputation in a complicated diabetic foot. Patients were presented with clinical photographs with images typical of pathologies for recognition. RESULTS: A total of 50 patients were included between January 2017 and July 2019. Of these 78% (38) patients were male, 22% (11) female. 22 patients (44%) recognized as the onset of diabetic foot an ulcer, 13 with blisters (26%), 10 with hyperkeratosis (20%), 5 with hammer toes (10%). CONCLUSIONS: 96% of patients were able to identify at least one injury as a predisposing factor for the onset of their complicated diabetic foot. The presentation of clinical photographs proved to be a patient-accepted tool. By identifying their initial injury we can determine which injury and where, where, it gave rise to the complication that led them to amputation. This information can help to perform preventive measures to limit amputations in the pelvic limbs of diabetic patients.

RESUMO

Objective: To investigate the recurrence and influencing factors of diabetic foot ulcer in patients with type 2 diabetes mellitus. Methods: Totally 185 type 2 diabetes patients with new-onset of diabetic foot ulcers admitted to Fuyang People's Hospital of Anhui Province from January 2011 to December 2015 were enrolled in this study, including 120 males and 65 females, aged 40-79 years. All the patients were followed up for 3 years, and their clinical data were retrospectively analyzed by the case-control study. The Kaplan-Meier cumulative recurrence curve was drawn according to the 3-year cumulative recurrence rate of diabetic foot ulcers. The time to visit, toe involvement, and amputation of involved toes in patients with recurrent diabetic foot ulcer were counted at the initial onset and the recurrence of the ulcers, respectively, and the data were statistically analyzed with t test and chi-square test. According to the recurrence of diabetic foot ulcers, the patients were divided into foot ulcer recurrence group and foot ulcer non-recurrence group. The gender, age, course of diabetes mellitus, length of hospital stay, visit time, body mass index, glycosylated hemoglobin HbA1c, total bilirubin, albumin, creatinine, cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL), triglycerides, hemoglobin, white blood cell count, toe involvement, toe amputation, ankle-brachial index, diabetic retinopathy (DR), diabetic peripheral neuropathy (DPN), diabetic nephropathy (DN), history of hypertension, cardio-cerebrovascular disease, smoking, residence, solitary life, and walking disorder of patients between the two groups were compared, and the data were statistically analyzed with t test and chi-square test. Log-rank test was performed on the indexes with P<0.1 in comparison between two groups, and the indexes with statistically significant differences in Log-rank test were analyzed by multivariate Cox regression analysis to screen the influencing factors of recurrence of diabetic foot ulcer. Results: (1) The 3-year cumulative recurrence rate of diabetic foot ulcers in 185 patients with type 2 diabetes mellitus was 47.0% (87/185). (2) For 87 patients with diabetic foot ulcer recurrence, compared with that at the initial onset of the ulcers, the visit time was significantly shorter (t=10.593, P<0.01), the toe amputation rate was significantly increased (χ(2)=5.118, P<0.05), but there was no obvious change in toe involvement at the recurrence of the ulcers. (3) There were statistically significant differences in age, course of diabetes mellitus, length of hospital stay, body mass index, glycosylated hemoglobin HbA1c, total bilirubin, albumin, creatinine, cholesterol, LDL, HDL, hemoglobin, white blood cell count, gender, toe amputation, ankle-brachial index, DR, history of cardio-cerebrovascular disease, solitary life, and walking disorder of patients between foot ulcer recurrence group (87 patients) and foot ulcer non-recurrence group (98 patients) (t=5.123, 4.242, 5.324, -24.572, 6.102, -1.984, -9.747, 3.226, 3.076, 3.646, -4.683, -7.502, 8.095, χ(2)=5.621, 18.433, 4.546, 5.785, 9.655, 7.625, 7.886, P<0.05 or P<0.01), while the rest of the indexes of patients between the two groups were similar. Log-rank test showed that the two groups had statistically significant differences in age, course of diabetes mellitus, length of hospital stay, glycosylated hemoglobin HbA1c, total bilirubin, albumin, creatinine, ankle-brachial index, DPN, and walking disorder (χ(2)=210.046, 44.837, 34.107, 98.685, 66.532, 294.451, 260.554, 5.012, 6.818, 11.160, P<0.05 or P<0.01). Age, total bilirubin, albumin, DPN, and walking disorder were the influencing factors for the recurrence of diabetic foot ulcers in patients with type 2 diabetes mellitus (hazard ratio=1.024, 0.678, 0.849, 2.335, 4.099, 95% confidence interval=1.001-1.047, 0.558-0.823, 0.797-0.904, 1.280-4.258, 2.044-8.223, P<0.05 or P<0.01). Conclusions: The 3-year cumulative recurrence rate of diabetic foot ulcers in patients with type 2 diabetes mellitus is relatively high, with the influencing factors being age, total bilirubin, albumin, DPN, and walking disorder.

RESUMO

This study aims to establish a diagnostic model of coronary heart disease (CHD) for diabetic foot (DF) patients.The clinical data of 489 hospitalized patients with DF were retrospectively analyzed in this case-control study. The patients were divided into the CHD group (DF with CHD, n = 212) and the control group (DF without CHD, n = 277). Univariate analysis was performed to screen for CHD-related risk factors, and multivariate logistic regression analysis was conducted to determine significant CHD risk factors. Scores were assigned according to the ratio of risk factors (OR) to establish a diagnostic model of CHD for patients with DF. The area under the ROC curve was used to test the application value of the diagnostic model.The logistic regression analysis showed that the risk factors for CHD in DF patients were age, duration of diabetes, toe-brachial index, hyperuricemia, and chronic renal insufficiency. The area under the ROC curve of the diagnostic model was 0.798 (0.759-0.837), the diagnostic point of CHD was 6 points, the diagnostic sensitivity was 69.3%, and the specificity was 76.5%.The established model has good diagnostic value and provides the basis for preliminary screening for CHD in patients with DF.

RESUMO

To investigate the relationship between diabetic foot complications (DFCs) and clinical characteristics, especially the number and types of first-degree family members with diabetes. A total of 8909 type 2 diabetes patients were enrolled. The clinical characteristics of these patients, including DFCs and family history of diabetes (FHD), were collected from medical records. Multiple regression was used to investigate the association between FHD and DFCs after adjusting for confounding factors. The patients with one and more than one first-degree family member with diabetes accounted for 18.7% and 12.8%, respectively. The proportions of the participants with a father with diabetes, a mother with diabetes, both parents with diabetes, siblings with diabetes, father and siblings with diabetes, mother and siblings with diabetes, and both parents and siblings with diabetes were 3.5%, 6.2%, 1.1%, 14.4%, 1.5%, 4%, and 0.7%, respectively. The multiple regression analysis showed that the number of family members with diabetes was positively associated with DFCs. However, among the different types of FHD, only the patients with a mother with diabetes showed a statistical association with DFCs. In addition to FHD, other factors, including gender, body mass index, platelet count, hemoglobin levels, albumin levels, high-density cholesterol levels, diabetic peripheral neuropathy, and the use of lipid-lowering agents, oral hypoglycemic agents, and insulin, were also associated with DFCs. DFCs were associated with different numbers of family members with diabetes and types of FHD. This association reveals the importance of genetic and environmental factors in DFCs and highlights the importance of adding FHD to public health strategies targeting detecting and preventing the disease.

RESUMO

BACKGROUND: Since the outbreak of novel coronavirus in 2019, the number of new coronavirus infections worldwide has been increasing, there is no effective treatment or vaccine. Novel coronavirus infection is closely related todiabetes, the mortality of diabetes with novel coronavirus pneumonia is significantly higher than that of non diabetic with novel coronavirus pneumonia, Diabetic foot is one of the common and serious complications of diabetes, however, no systematic study on novel coronavirus pneumonia adverse effects on diabetic foot has been found at home and abroad, however, this is a problem that can not be ignored. METHODS: We will search each database from the built-in until April 2021. The English literature mainly searches Cochrane Library, PubMed, EMBASE, and Web of Science, while the Chinese literature comes from CNKI, CBM, VIP, and Wangfang database. Simultaneously we will retrieval clinical registration tests and grey literatures, and he researches related to the adverse effects of novel coronavirus on diabetic foot were collected, The 2 researchers worked independently on literature selection, data extraction, and quality assessment. The dichotomous data is represented by relative risk, and the continuous is expressed by mean difference or standard mean difference, eventually the data is synthesized using a fifixed effect model or a random effect model depending on whether or not heterogeneity exists. The primary outcome was clinical response rate, C-reactive protein and procalcitonin. Secondary outcomes are mainly including mortality, amputation rate, wound healing time and nerve conduction velocity. Finally, meta-analysis was conducted by RevMan software version 5.3. RESULTS: The results of our research will be published in a peer-reviewed journal. INPLASY REGISTRATION NUMBER: 202080113.
