The Diabetic Foot and Peripheral Vascular Disease Study Group, Chinese Diabetes Society, released an expert advice Recommendations of Chinese Experts on the Standardized Diagnosis and Treatment of Diabetic Foot During Coronavirus Disease (COVID-19) Pandemic, and the International Diabetic Foot Care Group and D-Foot International released a document Fast-track Pathway for Diabetic Foot Ulceration During COVID-19 Crisis: A Document from International Diabetic Foot Care Group and D-Foot International during the 2020 outbreak, respectively. Both have the same goals, but the implementation focuses are different. The aim of this article is to give an interpretation of both expert advices in terms of the general principles, the epidemic prevention and control, the family, community and hospitalization management model of diabetic foot, the holistic principle of diabetic foot standardized management, and the telemedicine application in the late epidemic period.
ObjectiveTo explore the effectiveness and operative methods to treat first metatarsal diaphysis comminuted fractures with mini-plate via medial approach. MethodsBetween January 2012 and January 2013, 15 patients with first metatarsal shaft comminuted fractures were treated. There were 11 males and 4 females (6 left feet and 9 right feet) with an average age of 38.6 years (range, 27-56 years). The injury causes included falling injury in 6 cases, crash injury of heavy object in 7 cases, and sprain in 2 cases. The left side was involved in 6 cases and the right side in 9 cases. The time from injury to operation was 8.5 days on average (range, 7-10 days). According to AO classification, all cases were rated as 81(T)-C2 type. The surgical treatments included open reduction and internal fixation with mini-plate by medial approach. ResultsPrimary healing of incision was obtained in all cases, and no infection occurred. Twelve patients were followed up 18 months on average (range, 12-24 months). All fractures healed well, and the mean time of bone union was 11.5 weeks (range, 10-14 weeks). No loosening or breakage of internal fixation was observed. At last follow-up, the patients could walk with full weight-bearing, and had no pain. According to American Orthopaedic Foot and Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal scale, the mean score was 85.2 (range, 76-96). ConclusionAnatomic reduction and stable internal fixation are important for first metatarsal comminuted fracture, which is the key point for recovery of foot form and foot arch function. And the medial approach could achieve full exposure and improve the cosmetic results.

ObjectiveTo investigate the epidemiological characteristics and predisposing causes of diabetic foot ulcer (DFU) in the hospitalized patients with diabetic foot disease (DFD).MethodsThe clinical data of patients with DFD admitted to West China Hospital of Sichuan University between January 1st, 2012 and December 31st, 2018 were collected through the electronic medical record system. The demographic characteristics, blood glucose control status, and the predisposing causes of DFU were analyzed.ResultsA total of 1 022 DFD inpatients with an average age of (65.5±11.9) years old were included in this study, including 679 males and 343 females; 59.4% (513/864) of the patients had a college degree or above, but the patients with more severe DFD had lower educational level (χ2trend=19.554, P<0.001). The average time from diagnosis of diabetes mellitus to occurrence of DFD was (10.6±7.1) years, and 42.4% (433/1 022) of the patients had diabetes for over 10 years. Among the patients, 82.3% (841/1 022) treated diabetes irregularly, 56.2% (555/987) never monitored blood glucose, 51.2% (523/1 022) had a history of foot ulcers, and 8.6% (88/1 022) had a history of lower extremity or toe amputation. The average fasting blood glucose and hemoglobin A1c were (8.6±3.8) mmol/L and (8.2±2.1)%, respectively. There were 52.2% (525/1 006) and 94.4% (958/1 015) of the DFD patients companied with peripheral arterial disease and neuropathy, respectively. DFUs were mainly single (52.7%, 447/849) and neuro-ischemic ulcers (53.0%, 389/734). The main predisposing causes were physical causes (21.6%, 180/834) and trauma (19.2%, 160/834).ConclusionsThe patients with DFD have the characteristics of old age, long course of diabetes, irregular treatment of diabetes and poor control of blood glucose, combined with neurovascular diseases, and high recurrence rate of foot ulcer. Therefore, diabetes education, early screening of foot risk factors, and early intervention should be strengthened to prevent the occurrence and recurrence of DFU.
Objective To investigate the association between costs of hospitalized patients with diabetes mellitus and their complications in the West China Hospital of Sichuan University, so as to provide baseline data for further research. Methods We extracted the hospitalization case data of hospitalized patients with diabetes mellitus who were discharged from the department of endocrinology and metabolism, or discharged after being transferred to other departments for treatment from January 2011 to December 2012, using the hospital information system (HIS) of the West China Hospital of Sichuan University. The data included baseline of hospital patients, discharge diagnosis, hospitalization costs, and if their medical insurance had been registered in hospital. Then, we classified the diseases according to ICD-10 based on discharge diagnosis, coped the data using Excel 2010 software, and conducted statistical analysis using SPSS 13.0. Results a) In 2011, acute and chronic diabetes complication in diabetes inpatients were 11.9% (166/1 396) and 67.1% (930/1 396), respectively. Most of them had peripheral neuropathy and peripheral vascular disease. b) The most frequently-occurred complications were hypertension, followed by dyslipidemia, and osteoporosis. c) The median hospital stay was 13 days (7 to 9 days), and the median total cost of hospital/person-time was 6 578.88 yuan (4 186.93 to 10 953.89 yuan). d) The total cost and duration of hospitalization increased along with the increasing number of the chronic complications of diabetes. e) The diabetic foot patients were 255 person-times, the median duration of hospitalization was 18 days (13 to 29 days), and the median total cost of hospital/person-time was 16 672.19 yuan (10 903.93 to 28 530.37 yuan). Diabetes patients with foot complication had higher total costs and longer duration of hospitalization than those without foot complication. Conclusion Diabetes mellitus is one of the most important diseases in the department of endocrinology and metabolism, which is heavy disease burden. The costs of hospitalization and chronic complications are closely associated. Among these complications, diabetic foot is the heaviest disease burden.
Objective To evaluate the accuracy of newer-generation home blood glucose meter (Accu-Check? Integra) in patients with impaired glucose regulation (IGR) and newly-diagnosed type 2 diabetes mellitus. Methods A cross-sectional study was performed on 109 cases with newly-diagnosed type 2 diabetes or IGR who were asked to take oral glucose tolerance test (OGTT), while paired samples, that were Accu-Check? Integra in capillary blood glucose (CBG) and laboratory glucose in venous plasma glucose (VPG ), were taken simultaneously. Taking VPG as the reference value, the accuracy of the home glucose meter was assessed according to the international standardization organization (ISO), including, the accuracy was studied by means of Median absolute difference (Median AD) and Median absolute relative difference (Median RAD), the consistency of CBG and VPG was studied by Clarke Error Grid analysis, the correlation of CBG and VPG was analyzed according to liner regression analysis, and the sensitivity and specificity for hyperglycemia were also calculated. Results There were 292 VPG values paired with CBG values, among which 93.49% of CBG values met ISO home glucose meter criteria, the median AD was 7.2 mg/dL, and the median RAD was 4.76%. Paired glucose measurements from the Accu-Check Integra meter and laboratory glucose measurement demonstrated that 100% of paired points in the overall subject population fell in zones A and B of the Clarke Error Grid. The CBG value was well correlated to VPG value in the overall level, and the sensitivity and specificity were 94.6% and 95.7% respectively for hyperglycemia. Conclusion The newer-generation home blood glucose meter (Accu-Check? Integra) demonstrates a high degree of accuracy, and it can precisely report the real value of blood glucose.
