ObjectivesTo systematically review the efficacy and safety of autologous bone marrow cells therapy for patients with diabetic foot. GRADE system was used to evaluate the evidence quality of outcomes.MethodsWe searched databases including PubMed, EMbase, The Cochrane Library, CBM, WanFang Data and CNKI for randomized controlled trials (RCTs) about bone marrow cell transplantation in patients with diabetic foot from inception to February 28th 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was performed using RevMan 5.3 software. The evidence quality was evaluated by using GRADE profiler 3.6 software.ResultsFour RCTs were included. Meta-analysis showed that the bone marrow cell transplantation could decrease the rate of amputation (RR=0.08, 95%CI 0.00 to 1.32, P=0.08) and rest pain score (MD=–1.89, 95%CI –2.24 to –1.55, P<0.000 01), increase the rate of ameliorate ulcer healing (RR=2.01, 95%CI 1.45 to 2.79,P<0.000 1) and the quantity of new collateral vessels (MD=1.33, 95%CI 0.60 to 2.05,P<0.000 3). Besides, bone marrow cell transplantation could improve ankle-brachial index (MD=0.16, 95%CI 0.10 to 0.22,P<0.000 01) and transcutaneous arterial oxygen tension (MD=18.81, 95%CI 16.06 to 21.57,P<0.000 01). No adverse event was reported for all included studies. The qualities of evidence for all outcomes were rated as "low" to "very low".ConclusionBased on the current evidence, autologous bone marrow cells transplantation therapy has a certain effect and it is safe for patients with diabetic foot. However, due to the limited quantity and quality of included studies, the above conclusions are still needed more multicenter clinical trials with large sample size to confirm.
Diabetic foot is one of the most common complications of diabetes. The incidence of diabetic foot is high and its treatment is difficult. The cost of treating this disease is huge, which brings a huge burden to patients, families, and society. According to the development process of diabetic foot, this article reviews the rehabilitation nursing of diabetic foot from the perspective of rehabilitation nursing problems, intervention measures, and intervention modes. The rehabilitation nursing problems are summarized as body functions, body structures, activities, and participation; the intervention measures involve rehabilitation education, skin nursing, exercise therapy, mental nursing, hyperbaric oxygen therapy, platelet-rich plasma therapy, and rehabilitation aids; the intervention modes include preventive rehabilitation nursing, in-hospital rehabilitation nursing, community and family rehabilitation nursing, and palliative nursing.
Objective The self-defined multidisciplinary (endocrinology, vascular surgery, and orthopedics) scoring system (EMO scoring system for short) was designed. The feasibility of the EMO scoring system to guide the proximal tibial transverse transport (TTT) for diabetic foot wounds was preliminarily explored. Methods Based on the current commonly used clinical criteria for diabetic foot judgment, expert consensus, guidelines, and related research progress in the treatment of diabetic foot wounds, combined with clinical experience, a set of EMO scoring systems including endocrinology, vascular surgery, and orthopedics was formulated. The criteria for selecting conservative treatment, TTT after baseline improvement, and TTT based on scoring results was proposed. A total of 56 patients with diabetic foot wounds who were admitted between September 2017 and July 2022 and met the selection criteria was taken as the study subjects. Among them, 28 patients were treated with TTT and 28 patients were treated conservatively. The patients were graded according to the EMO scoring system, the corresponding treatment methods were selected, and the actual treatment methods and results of the patients were compared. Results The EMO scoring system was formed through literature retrieval and clinical experiences. The system included three criteria, namely endocrinology (E), macrovascular disease (M), and orthopedics (O), which were divided into multiple subtypes according to the relevant evaluation items, and finally the diabetic foot wound was divided into 8 types, which correspondingly selected TTT, TTT after baseline improvement, and conservative treatment. All 56 patients were followed up 12 months after treatment. Among them, the wound healing rate of the TTT group was 85.71% (24/28), which was higher than that of the conservative treatment group [53.57% (15/28)]. At 12 week after treatment, CT angiography showed that there were more small blood vessels in the wound and ipsilateral limb in TTT group than in the conservative treatment group. Based on the EMO scoring system, 14 of the 56 patients needed conservative treatment, 29 patients needed TTT, and 13 patients needed TTT after baseline improvement. Compared with the clinical data of the patients, the wound healing rate of the patients judged to be TTT was 75.86% (22/29), of which 21 cases were actually treated with TTT, and the healing rate was 90.48%; 8 patients were treated conservatively, and the healing rate was 37.50%. The wound healing rate of the patients judged to be conservative treatment was 92.86% (13/14), of which 1 case was actually treated with TTT, and the healing rate was 100%; 13 cases were treated conservatively, and the healing rate was 92.31%; 1 case experienced minor amputation. The wound healing rate of the patients judged to TTT after baseline improvement was only 30.77% (4/13), of which 6 cases were actually treated with TTT, and the healing rate was 66.67%; 7 cases were treated conservatively, and the healing rate was 0. Conclusion EMO scoring system can comprehensively evaluate the diabetic foot wounds, and make personalized judgment on whether TTT treatment is feasible, so as to improve the level of diabetic foot wound treatment and the prognosis of patients.
ObjectiveTo explore the causes and management of the complications in diabetic foot treated with tibial transverse transport (TTT). MethodsBetween September 2015 and September 2019, 196 patients with diabetic foot were treated with TTT. There were 109 males and 87 females, with an average age of 67.6 years (range, 45-86 years). According to Wagner’s classification, there were 124 cases of grade 3, 62 cases of grade 4, and 10 cases of grade 5; the course of disease was 1-12 months, with an average of 2.6 months. All patients underwent the minimally invasive tibial osteotomy. The osteotomy site was the middle and lower tibia in 62 cases and the middle and upper tibia in 134 cases. The area of osteotomy was 20 cm2 in 83 cases and 7.5 cm2 in 113 cases. The osteotomy block was moved back and forth once in 92 cases and twice in 104 cases. The complications were recorded, including secondary fracture at tibial osteotomy, skin necrosis in osteotomy area, and pin tract infection. ResultsAmong 196 patients, 41 cases (20.9%) had complications. Nine cases (4.6%) had secondary fracture at tibial osteotomy, among which 6 cases (9.6%) of middle and lower segment osteotomies and 3 cases (2.2%) of middle and upper segment osteotomies. The incidence between the patients with different osteotomy sites was significant (χ2=5.354, P=0.021). The area of osteotomy was 20 cm2 in 5 cases (6.0%) and 7.5 cm2 in 4 cases (3.5%). There was no significant difference in the incidence between patients with different areas (χ2=0.457, P=0.499). Skin necrosis occurred in the osteotomy area in 12 cases (6.1%), all of which were moved back and forth once. There was a significant difference in the incidence between patients who were treated with transport once and twice (P=0.001). There were 18 cases (9.1%) with pin tract infection, including 12 cases (6.1%) with mild infection and 6 cases (3.0%) with severe infection. There was no significant difference in the incidence between the patients with mild and severe infections (P=0.107).ConclusionTTT is an effective method to treat diabetic foot, but there are complications such as secondary fracture at tibial osteotomy, skin necrosis in osteotomy area, and pin tract infection during transport. Preoperative evaluation of indication, standardization of osteotomy mode, size and position of osteotomy block, establishment of individualized removal plan, and strengthening of pin track nursing after operation can effectively reduce complications.
Objective To analyze the methods of treating diabetic feet and to evaluate the optimal method. Methods The clinical data of 115 patients (137 legs) with diabetic feet were retrospectively analyzed. Results Seventy-one affected legs were treated with balloon dilation or stenting (11 with additional debridement of local ulcer), 12 legs were treated by femoral-popliteal arterial bypass (5 with additional debridement of local ulcer), and 31 legs were treated by debridement of local ulcer or amputation merely, and another 23 legs were treated by medical therapy. All diabetic feet treated by surgical treatment were improved obviously without death and severe complications, while 2 cases with medicine therapy died. Conclusion Because of the complexion of the diabetic foot, it should be treated individually, and the key point is to deal with the vascular lesions.
ObjectiveTo systematically evaluate the potential effectiveness of JinHuang powder in the treatment of diabetic foot ulcers (DFUs). MethodsDatabases including PubMed, The Cochrane Library, Web of Science, CBM, WanFang data, VIP and CNKI were electronically searched from their inception to December 2013, to identify randomized controlled trials (RCTs) about JinHuang powder for DFUs. Two reviewers screened literature according to the inclusion and exclusion criteria, extracted data and assessed the methodological quality of included studies, and then meta-analysis was performed by using RevMan 5.1 software. ResultsA total of 3 RCTs involving 198 patients were included. The results of meta-analysis showed that:the JinHuang powder group were superior to the control group in total effective rate (RR=1.25, 95%CI 1.10 to 1.41, P=0.00) and the wound healing time (SMD=-3.32, 95%CI -5.69 to -0.96, P=0.00). ConclusionCurrent evidence suggests that the JinHuang powder is an effective therapeutic method for DFUs. Because of the limitations of quantity and quality of the eligible studies, large sample size studies are needed to validate the conclusion.
Tibial transverse transport (TTT) was firstly applied to treat thromboangiitis obliterans successfully by Professor QU Long in China in 2000. Based on this, the team of Professor HUA Qikai in the First Affiliated Hospital of Guangxi Medical University applied this technique to treat diabetic foot since 2013, and until now, more than 500 patients underwent this treatment with excellent effectiveness including a salvage rate as high as 96.1%. Our team also improved this technique in many aspects, and developed a TTT-based classification system and treatment for diabetic foot. We also explored the underlying mechanism of TTT treatment using imaging, histology, and other basic research methods. To further promote the application of this technique in clinic, we reported the findings from our cases and reviewed our previous findings in this study.
ObjectiveTo overview the systematic reviews on efficacy and safety of hyperbaric oxygen in treatment of diabetic foot.MethodsCNKI, CBM, VIP, WanFang Data, The Cochrane Library, PubMed and EMbase databases were searched to collect systematic reviews or meta-analyses on the efficacy and safety of hyperbaric oxygen therapy for diabetic foot from inception to November 17th, 2019. Two researchers independently screened literature and extracted data. Then, AMSTAR 2 tool and PRISMA statement were used to evaluate the methodological quality and reporting quality of included systematic reviews, and the outcome indicators were comprehensively analyzed.ResultsA total of 10 systematic reviews were included. The results of AMSTAR 2 suggested that 6 systematic reviews were of extremely low quality, 3 of low quality, and 1 of high quality. The PRISMA score ranged from 16.5 to 27. The results of the included systematic reviews showed that hyperbaric oxygen therapy might be superior to other interventions in ulcer healing rate and large amputation rate without increasing the risk of adverse events. ConclusionsThe existing systematic reviews/meta-analysis evidence shows that hyperbaric oxygen therapy may have certain curative effect on diabetic foot, however, its methodology and report quality evaluation are insufficient.
To investigate the surgical strategy of diabetic foot (DF) and analyze the therapeutic efficacy. Methods From July 2004 to July 2007, 36 patients (22 males and 14 females) with DF were treated, with an average age of 57 years(43-82 years). The disease course of diabetes was 3 months to 27 years(12 years on average) and the disease course of DF was 1 month to 2 years (7 months on average). According to Wagner classification of DF, there were 3 cases of grade 1, 12 cases of grade 2, 10 cases of grade 3, 7 cases of grade 4 and 4 cases of grade 5. The locations of ulcer were ankle and heel in 9 cases, medial part of foot in 14 cases, in lateral part of foot in 8 cases and sinus formation in 5 cases. The ulcer sizes ranged from 4 cm × 2 cm-18 cm × 9 cm. Initial management of these patients included control of blood sugar level, proper hydration, administration of antibiotics, treatment of coexisting diseases, and repeated debridements of wounds when necessary. Ulcers were treated with debridement and spl it skin transplantation in 3 cases of grade 1, with debridement and drainage of abcesses and spl it skin transplantation in 12 of grade 2, with debridement and transplantation of flap in 17 of grade 3 and grade 4, and with transplantation of fascial flap in 5 cases of sinus; ulcers were treated firstly with artery bypass of lower extremity, and then treated with local amputation of foot to avoid high-level amputation and to save more function of foot in 4 of grade 5. Results In 36 cases, wound in 31 cases (86.1%) cured primaryly, wound did not heal in 1 patient (2.1%) and received re-amputation, there were 2 deaths because of infection with multiple organ failure postoperatively. Twenty-nine cases were followed up 8 months (range, 6 -15 months). Eight patients developed new ulcers, with 3 lesions in situ and 5 lesions in new site. Conclusion Surgicalregimen could play an important role in treatment of diabetic foot. According to different grades of DF, there were differentstrategies in deal ing with the accompanied inflammation and ulcer. An active and comprehensive surgical treatment of DF could save the foot, avoid the high-level amputation and result in more functional extremity.
