Abstract
AIMS/HYPOTHESIS Diabetic foot disease (DFD) is a leading cause of hospital admissions and amputations. Global trends in diabetes-related amputations have been previously reviewed, but trends in hospital admissions for multiple other DFD conditions have not. This review analysed the published incidence of hospital admissions for DFD conditions (ulceration, infection, peripheral artery disease [PAD], neuropathy) and diabetes-related amputations (minor and major) in nationally representative populations. METHODS PubMed and Embase were searched for peer-reviewed publications between 1 January 2001 and 5 May 2022 using the terms 'diabetes', 'DFD', 'amputation', 'incidence' and 'nation'. Search results were screened and publications reporting the incidence of hospital admissions for a DFD condition or a diabetes-related amputation among a population representative of a country were included. Key data were extracted from included publications and initial rates, end rates and relative trends over time summarised using medians (ranges). RESULTS Of 2527 publications identified, 71 met the eligibility criteria, reporting admission rates for 27 countries (93% high-income countries). Of the included publications, 14 reported on DFD and 66 reported on amputation (nine reported both). The median (range) incidence of admissions per 1000 person-years with diabetes was 16.3 (8.4-36.6) for DFD conditions (5.1 [1.3-7.6] for ulceration; 5.6 [3.8-9.0] for infection; 2.5 [0.9-3.1] for PAD) and 3.1 (1.4-10.3) for amputations (1.2 [0.2-4.2] for major; 1.6 [0.3-4.3] for minor). The proportions of the reported populations with decreasing, stable and increasing admission trends were 80%, 20% and 0% for DFD conditions (50%, 0% and 50% for ulceration; 50%, 17% and 33% for infection; 67%, 0% and 33% for PAD) and 80%, 7% and 13% for amputations (80%, 17% and 3% for major; 52%, 15% and 33% for minor), respectively. CONCLUSIONS/INTERPRETATION These findings suggest that hospital admission rates for all DFD conditions are considerably higher than those for amputations alone and, thus, the more common practice of reporting admission rates only for amputations may substantially underestimate the burden of DFD. While major amputation rates appear to be largely decreasing, this is not the case for hospital admissions for DFD conditions or minor amputation in many populations. However, true global conclusions are limited because of a lack of consistent definitions used to identify admission rates for DFD conditions and amputations, alongside a lack of data from low- and middle-income countries. We recommend that these areas are addressed in future studies. REGISTRATION This review was registered in the Open Science Framework database ( https://doi.org/10.17605/OSF.IO/4TZFJ ).

Arch Orthop Trauma Surg 2023; 143:645-656. [PMID: 34370043 PMCID: PMC9925494 DOI: 10.1007/s00402-021-04106-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Accepted: 07/26/2021] [Indexed: 11/25/2022]
Abstract
INTRODUCTION Repetitive minor amputations carry the concomitant risks of multiple surgical procedures, major amputations have physical and economical major drawbacks. The aim of this study was to evaluate whether there is a distinct number of minor amputations predicting a major amputation in the same leg and to determine risk factors for major amputation in multiple minor amputations. MATERIALS AND METHODS A retrospective chart review including 429 patients with 534 index minor amputations between 07/1984 and 06/2019 was conducted. Patient demographics and clinical data including number and level of re-amputations were extracted from medical records and statistically analyzed. RESULTS 290 legs (54.3%) had one or multiple re-amputations after index minor amputation. 89 (16.7%) legs needed major amputation during follow up. Major amputation was performed at a mean of 32.5 (range 0 - 275.2) months after index minor amputation. No particular re-amputation demonstrated statistically significant elevated odds ratio (a.) to be a major amputation compared to the preceding amputation and (b.) to lead to a major amputation at any point during follow up. Stepwise multivariate Cox regression analysis revealed minor re-amputation within 90 days (HR 3.8, 95% CI 2.0-7.3, p <0.001) as the only risk factor for major amputation if at least one re-amputation had to be performed. CONCLUSIONS There is no distinct number of prior minor amputations in one leg that would justify a major amputation on its own. If a re-amputation has to be done, the timepoint needs to be considered as re-amputations within 90 days carry a fourfold risk for major amputation. LEVEL OF EVIDENCE Retrospective comparative study (Level III).

DIABETES & METABOLISM 2022; 48:101378. [PMID: 35872122 DOI: 10.1016/j.diabet.2022.101378] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/08/2022] [Revised: 06/25/2022] [Accepted: 07/18/2022] [Indexed: 06/15/2023]
Abstract
AIM Physical activity improves insulin resistance, inhibits inflammation, and decreases the incidence of cardiovascular disease. These are major causes of death in patients with diabetes. METHODS The Taiwan National Health Interview Survey collected baseline characteristics of socioeconomic level, education, marriage, and health behaviour, including leisure time physical activity in 2001, 2005, 2009, and 2013. The National Health Insurance research dataset 2000-2016 contained detailed information on medical conditions, including all comorbidities. All-cause and cardiovascular deaths were confirmed by the National Death Registry. RESULTS A total of 4859 adults with type 2 diabetes were included in the analysis; 2389 (49 %) were men and the mean±SD age was 60±13 years. Kaplan-Meier curve of all-cause (log-rank P<0.001) and cardiovascular death (log-rank P=0.038) categorized by leisure-time physical activity showed a significant difference. The multivariable Cox regression model showed that those who had more leisure time physical activity had a significantly lower risk of all-cause death than those with no physical activity (physical activity of 1-800 MET-min/week HR = 0.66, 95% CI: 0.54-0.81, physical activity of >800 MET-min/week HR = 0.67, 95% CI: 0.56-0.81). A significant trend was also observed (P <0.001). Similar results were also observed for cardiovascular mortality (physical activity of 1-800 MET-min/week HR = 0.54, 95% CI: 0.36-0.84, physical activity of >800 MET-min/week HR = 0.78, 95% CI: 0.55-1.13). CONCLUSION For those with diabetes, increased leisure-time physical activity significantly reduced risk of all-cause and cardiovascular death. Further research is warranted to determine the proper prescription for physical activity to prolong healthy life.

Risk factors for diabetic foot complications among patients with type 2 diabetes in Austria-A registry-based retrospective cohort study. ENDOCRINOLOGY DIABETES & METABOLISM 2021; 4:e00286.

Abstract
Aims Diabetic foot complications, a serious consequence of diabetes mellitus, are associated with a tremendous burden on both individual patients and health care systems. Since prevention strategies may reduce the incidence of this complication, identification of risk factors in large longitudinal studies is essential to optimize early detection and personalized screening of patients at increased risk. Materials and methods We conducted a registry‐based retrospective cohort study using data from 10,688 patients with type 2 diabetes mellitus aged ≥18 years. Cox regression models were used to identify risk factors for foot complications while adjusting for potential confounders. Results We observed 140 diabetic foot complications in our patient cohort. The multivariate Cox regression model revealed neuropathy, peripheral arterial disease and male gender as being positively associated with foot complications. The same effect was detected for nephropathy in the time >10 years after T2DM diagnosis. For higher age at diagnosis and use of insulin, however, a negative association was retrieved. Conclusion Male gender and several diabetes‐related comorbidities were identified as risk factors for subsequent initial foot complications in patients with type 2 diabetes mellitus. These findings suggest that personalized early detection of patients at increased risk might be feasible by using information on demographics, medical history and comorbidities.

Abstract
BACKGROUND Diabetic foot complications, one of the most severe late complications of type 2 diabetes mellitus, are associated with a tremendous personal and financial burden. In order to drive the prevention of diabetic foot complications forward and facilitate early detection and personalized screening of high-risk patients, longitudinal studies are needed to identify risk factors associated with diabetic foot complications in large patient datasets. METHODS This is a retrospective cohort study on 3002 patients with type 2 diabetes mellitus aged ≥ 18 years without prior foot complications. The data were collected between 2006 and 2017 in an Austrian hospital department specialized for diabetic patients. In addition to a univariate Cox regression analysis, multivariate Cox regression models were established to identify independent risk factors associated with diabetic foot complications and adjust for potential confounders. RESULTS We observed a total of 61 diabetic foot complications in 3002 patients. In the multivariate Cox regression model, significant risk factors (hazard ratio, 95% confidence interval) for foot complications were age at diagnosis > 70 years (3.39, 1.33-8.67), male gender (2.55, 1.42-4.55), neuropathy (3.03, 1.74-5.27), peripheral arterial disease (3.04, 1.61-5.74), hypertension > 10 years after diagnosis (2.32, 1.09-4.93) and HbA1c > 9% (2.44, 1.02-5.83). CONCLUSION The identified risk factors for diabetic foot complications suggest that personalized early detection of patients at high risk might be possible by taking the patient's clinical characteristics, medical history and comorbidities into account. Modifiable risk factors, such as hypertension and high levels of blood glucose might be tackled to reduce the risk for diabetic foot complications.

Using machine learning to identify diabetes patients with canagliflozin prescriptions at high-risk of lower extremity amputation using real-world data. Pharmacoepidemiol Drug Saf 2021; 30:644-651. [PMID: 33606340 DOI: 10.1002/pds.5206] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Accepted: 02/16/2021] [Indexed: 02/06/2023]
Abstract
AIMS Canagliflozin, a sodium-glucose cotransporter 2 inhibitor indicated for lowering glucose, has been increasingly used in diabetes patients because of its beneficial effects on cardiovascular and renal outcomes. However, clinical trials have documented an increased risk of lower extremity amputations (LEA) associated with canagliflozin. We applied machine learning methods to predict LEA among diabetes patients treated with canagliflozin. METHODS Using claims data from a 5% random sample of Medicare beneficiaries, we identified 13 904 diabetes individuals initiating canagliflozin between April 2013 and December 2016. The samples were randomly and equally split into training and testing sets. We identified 41 predictor candidates using information from the year prior to canagliflozin initiation, and applied four machine learning approaches (elastic net, least absolute shrinkage and selection operator [LASSO], gradient boosting machine and random forests) to predict LEA risk after canagliflozin initiation. RESULTS The incidence rate of LEA was 0.57% over a median 1.5 years follow-up. LASSO produced the best prediction, yielding a C-statistic of 0.81 (95% CI: 0.76, 0.86). Among individuals categorized in the top 5% of the risk score, the actual incidence rate of LEA was 3.74%. Among the 16 factors selected by LASSO, history of LEA [adjusted odds ratio (aOR): 33.6 (13.8, 81.9)] and loop diuretic use [aOR: 3.6 (1.8,7.3)] had the strongest associations with LEA incidence. CONCLUSIONS Our machine learning model efficiently predicted the risk of LEA among diabetes patients undergoing canagliflozin treatment. The risk score may support optimized treatment decisions and thus improve health outcomes of diabetes patients.

Systematic Review of Clinical Practice Guidelines for Individuals With Amputation: Identification of Best Evidence for Rehabilitation to Develop the WHO's Package of Interventions for Rehabilitation. Arch Phys Med Rehabil 2021; 102:1191-1197. [PMID: 33412108 DOI: 10.1016/j.apmr.2020.11.019] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Revised: 11/05/2020] [Accepted: 11/08/2020] [Indexed: 01/16/2023]
Abstract
OBJECTIVES To report the results of the systematic search performed to identify interventions and related evidence for rehabilitation of individuals with amputation based on the current evidence from clinical practice guidelines (CPG). DATA SOURCES Pubmed, Pedro, CINAHL, Embase, Google Scholar, and multiple guideline databases (date restriction, 2008-2018). STUDY SELECTION Exclusion criteria were no CPG, not reporting on rehabilitation, published before 2008, developed for health conditions other than amputation, presence of conflict of interest (financial or nonfinancial), lack of information on the strength of the recommendation, and lack of quality assessed by the "Appraisal of Guidelines for Research and Evaluation." DATA EXTRACTION Data extraction was done using a standardized form, which comprised information on the recommendation, the strength of recommendation and the quality of the evidence used to inform the recommendation. DATA SYNTHESIS We included 4 guidelines, providing a total of 217 recommendations (20 on assessments, 131 on interventions, and 66 on service provision). Most recommendations concerned pain management, education, pre- and postoperative management, and residual limb care. The strength of recommendation was generally weak to intermediate. The level of evidence mostly compromised expert opinions, with only 6.9% (15 of 217) being provided by randomized controlled trials, systematic reviews, or meta-analyses. CONCLUSIONS The field of amputation is well covered for recommended interventions, but the level of evidence is generally low and is based mostly on expert opinion. Some important domains are not covered (eg, vocation and education, sexual and/or intimate relationships, activities of daily living or leisure activities, education concerning socket/liner fitting). There is also a lack of description of the contents of training and rehabilitation programs. This should be taken into account for the development of future guidelines.

Abstract
Aims With increasing numbers of patients with type 2 diabetes mellitus (T2DM) worldwide, the number of associated diabetic foot complications might also increase. This systematic review was performed to summarize published data about risk factors for the diabetic foot (DF) syndrome in order to improve the identification of high-risk patients. Materials and methods Six electronic databases were searched for publications up to August 2019 using predefined stringent inclusion and exclusion criteria. Results Of 9,476 identified articles, 31 articles from 28 different study populations fulfilled the criteria for our evaluation. The overall quality of the studies was good, and the risk of bias was low. There was large heterogeneity among the studies concerning study protocols and patient populations analysed. A total of 79 risk factors were analysed within this review. The majority of studies described a consistently positive association with different outcomes of interest related to DF for gender, peripheral neuropathy, retinopathy, nephropathy, poor glycaemic control, insulin use, duration of diabetes, smoking and height. For age, hypertension, dyslipidaemia and body mass index, the results remain inconsistent. Conclusion A most up-to-date literature review resulted in glycaemic control and smoking as the only amenable risk factors with a consistently positive association for DF. Due to the high personal and financial burden associated with DF and the large heterogeneity among included studies, additional longitudinal studies in large patient populations are necessary to identify more modifiable risk factors that can be used in the prediction and prevention of DF complications.

Abstract
AIMS/HYPOTHESIS We aimed to describe trends in rates of hospitalisation for lower extremity amputation (LEA) and 1 year mortality rates after LEA in people with diabetes in Hong Kong between 2001 and 2016. METHODS The Hong Kong Diabetes Surveillance Database is a territory-wide population-based diabetes cohort (N = 770,078) identified from the Hong Kong Hospital Authority electronic medical system. We identified LEA events using ICD-9 procedure codes and 1 year mortality after LEA from linkage to the Hong Kong Death Registry. Joinpoint regression models were used to describe the trends. RESULTS Between 2001 and 2016, 6113 hospitalisations for LEAs in men and 4149 in women were recorded in the Hong Kong Diabetes Surveillance Database. The rates of minor LEAs declined by 48.6% (average annual per cent change [AAPC]: -3.8; 95% CI -5.7, -1.9) in men and by 59.5% (AAPC: -6.3; 95% CI -10.6, -1.8) in women. The rates of major LEAs declined by 77.9% (AAPC: -8.0; 95% CI -9.6, -6.5) in men and by 79.3% (AAPC: -10.4; 95% CI -13.1, -7.6) in women. The cumulative 1 year mortality rates after minor and major LEAs were 18.5% and 41.8% in men, and 21.3% and 42.0% in women, respectively, for the whole period. No change was detected in 1 year mortality rates during the surveillance in both sexes. CONCLUSIONS/INTERPRETATION Although hospitalisation rates for LEAs have declined overall in people with diabetes, there were no improvements in 1 year mortality rates after LEA. Continuous efforts are needed to further prevent LEAs and improve the survival rate of people undergoing LEAs. Graphical abstract.

Age- and sex-specific incidence of non-traumatic lower limb amputation in patients with type 2 diabetes mellitus in a U.S. claims database. Diabetes Res Clin Pract 2020; 169:108452. [PMID: 32949656 DOI: 10.1016/j.diabres.2020.108452] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 07/22/2020] [Accepted: 09/14/2020] [Indexed: 02/08/2023]
Abstract
AIM To estimate age- and sex-specific incidence rates (IRs) of non-traumatic lower limb amputations (LLA) in patients with type 2 diabetes mellitus (T2DM) using a claims database from the United States (US). METHODS Patients with T2DM 18 years and older were identified using the Truven Health MarketScan database from January 1, 2007 to September 30, 2018. The overall and age- and sex-specific IRs of all non-traumatic LLA, minor LLA (amputation at or below the ankle), and major LLA (amputation above ankle) were calculated. RESULTS Among the 6,117,981 patients with T2DM, 14,627 LLA events occurred (minor LLA; 72.8%; major LLA: 27.2%). The IRs (95% CI) of all LLA, minor LLA, and major LLA per 1000 person-years or PY were 0.86 (0.85, 0.88), 0.63 (0.62, 0.64), and 0.23 (0.23, 0.24), respectively. The IR (95% CI) of all LLA per 1000 PY in males was higher compared to females [1.24 (1.22, 1.26) vs. 0.46 (0.45, 0.48)]. The incidence of all LLA increased with an increasing age (highest IR in age-group of ≥80 years). CONCLUSIONS This study identified males and older patients with T2DM at higher risk of developing LLA in the US, warranting further exploration of risk factors of LLA in these subgroups.

Abstract
INTRODUCTION Despite improvements in endovascular interventions and multidisciplinary approaches, improving clinical outcomes and increasing limb salvage have become increasingly challenging. This prospective study investigated the associations of cilostazol treatment with clinical outcomes and predictive factors in patients with diabetes mellitus (DM) and critical limb ischemia (CLI) after endovascular revascularization of the affected angiosome. METHODS In this study, 172 consecutive patients with CLI (Fontaine levels III-IV) received cilostazol treatment after successful endovascular intervention according to the angiosome concept, and their primary patency rates and cardiovascular and amputation events during a 24-month follow-up period were assessed. RESULT The 24-month primary patency rate, mortality rate, and amputation rate were better in the patients under long-term cilostazol treatment (P < 0.001, P = 0.029, and P = 0.014). Weighted multivariate Cox analyses with a propensity scoring-based method showed that long-term cilostazol treatment [hazard ratio (HR) 0.2, 95% confidence interval (CI) 0.11-0.36, P < 0.001], direct revascularization (DR) (HR 0.46, 95% CI 0.28-0.74, P = 0.002), and supervised exercise (HR 0.4, 95% CI 0.24-0.66, P < 0.001) were independently associated with primary patency. Patients with lower-extremity amputation (LEA) had a higher risk of coronary artery disease (CAD) and mortality. Cellulitis and neuropathy were independently associated with LEA events (cellulitis: HR 2.89, 95% CI 1.66-5.05, P < 0.001; neuropathy: HR 2.2, 95% CI 1.31-3.7, P = 0.003). CONCLUSION Our results showed that patients with DM who received cilostazol treatment for more than 3 months had significantly better outcomes and decreased amputation and mortality rates after DR, and cellulitis and neuropathy were highly associated with the risk of limb loss. A large-scale randomized trial should be conducted in the future to confirm these results. TRIAL REGISTRATION Taipei Veterans General Hospital (TVGH) IRB no. 2013-08-020B. Registered 30 August 2013.

Abstract
Background and objectives: Diabetes mellitus (DM) stands out among the most important public health problems worldwide since it represents a high burden on health systems and is associated with higher hospitalization rates, and a higher incidence of cardiovascular diseases. Amputations are among the most common complications, leading to disability and increasing care costs. This research aims to analyze the prevalence of DM-related amputations, comorbidities and associated risk factors in the diabetic population residing in the State of Espírito Santo, Brazil. Materials and Methods: This is a quantitative, exploratory, cross-sectional study with a time series design and the use of secondary data registered and followed by the system of Registration and Monitoring of Hypertension and Diabetes-SisHiperdia. Results: The sample consisted of 64,196 diabetic patients, out of them, 3.9% had type 1 DM, 10.9% with type 2 DM, and 85.2% with DM coexisting with hypertension. Most were female (66.6%), aged 40 to 59 years (45.6%), and 60 years and older (45.2%). The prevalence of DM-related amputations in the analyzed sample was 1.2% in type 1 DM, 1.5% in type 2 DM, and 2.2% in concomitant DM and hypertension. Higher amputation rates were observed in males in the age group above 60 years in type 1 DM and type 2 DM and were slightly higher in the age groups up to 29 years in DM with hypertension. A higher prevalence of amputation was related to smoking, physical inactivity, acute myocardial infarction (AMI), stroke, chronic kidney disease (CKD), and diabetic foot (DF) in all types of DM. Conclusions: The present study showed a significant prevalence of DM-related amputations. An increased prevalence was evidenced when correlated with smoking, physical inactivity, AMI, stroke, CKD, and DF with significant statistical associations, except for a sedentary lifestyle in type 1 DM.

Population-based secular trends in lower-extremity amputation for diabetes and peripheral artery disease. CMAJ 2020; 191:E955-E961. [PMID: 31481423 DOI: 10.1503/cmaj.190134] [Citation(s) in RCA: 42] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/09/2019] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND The evolving clinical burden of limb loss secondary to diabetes and peripheral artery disease remains poorly characterized. We sought to examine secular trends in the rate of lower-extremity amputations related to diabetes, peripheral artery disease or both. METHODS We included all individuals aged 40 years and older who underwent lower-extremity amputations related to diabetes or peripheral artery disease in Ontario, Canada (2005-2016). We identified patients and amputations through deterministic linkage of administrative health databases. Quarterly rates (per 100 000 individuals aged ≥ 40 yr) of any (major or minor) amputation and of major amputations alone were calculated. We used time-series analyses with exponential smoothing models to characterize secular trends and forecast 2 years forward in time. RESULTS A total of 20 062 patients underwent any lower-extremity amputation, of which 12 786 (63.7%) underwent a major (above ankle) amputation. Diabetes was present in 81.8%, peripheral artery disease in 93.8%, and both diabetes and peripheral artery disease in 75.6%. The rate of any amputation initially declined from 9.88 to 8.62 per 100 000 between Q2 of 2005 and Q4 of 2010, but increased again by Q1 of 2016 to 10.0 per 100 000 (p = 0.003). We observed a significant increase in the rate of any amputation among patients with diabetes, peripheral artery disease, and both diabetes and peripheral artery disease. Major amputations did not significantly change among patients with diabetes, peripheral artery disease or both. INTERPRETATION Lower-extremity amputations related to diabetes, peripheral artery disease or both have increased over the last decade. These data support renewed efforts to prevent and decrease the burden of limb loss.

Abstract
Background To assess the prevalence of urban-rural disparity in lower extremities amputation (LEA) among patients with diabetes and to explore whether patient-related or physician-related factors might have contributed to such disparity. Methods This was a population-based study including patients with diabetes aged ≥55 years from 2009 to 2013. Among them, 9236 received LEA. Data were retrieved from Taiwan’s National Health Insurance (NHI) claims. A multiple Poisson regression model was also employed to assess the urban-rural difference in LEA prevalence by simultaneously taking into account socio-demographic variables and density of practicing physicians. Results Between 2009 and 2013, the annual prevalence of LEA declined from 30.4 to 20.5 per 10,000 patients. Compared to patients from urban areas, those who lived in sub-urban and rural areas suffered from a significantly elevated prevalence of LEA, with a prevalence rate ratio (PRR) of 1.47 (95% CI, 1.39–1.55) and 1.68 (95% CI, 1.56–1.82), respectively. The density of physicians who presumably provided diabetes care can barely explain the urban-rural disparity in LEA prevalence. Conclusions Although the universal health insurance has largely removed financial barriers to health care, the urban-rural disparity in LEA prevalence still exists in Taiwan after nearly two decades of the NHI program.

Abstract
OBJECTIVE The incidence and prevalence of end-stage renal disease (ESRD) in Taiwan have been ranked the highest worldwide. Therefore, the National Health Insurance Administration has implemented the pre-ESRD pay-for-performance (P4P) programme since November 2006, which had significantly reduced the incidence of dialysis and all-cause mortality. This study aimed to identify the factors associated with the enrolment in the pre-ESRD P4P programme. DESIGN Cross-sectional study. SETTING The National Health Insurance research database 2007-2012 in Taiwan. PARTICIPANTS Patients with prevalent pre-ESRD aged more than 18 years between January 2007 and December 2012 were enrolled. Patient demographics and hospital characteristics between P4P and non-P4P groups were compared. A logistic regression model was used to analyse the factors associated with P4P enrolment, and a generalised estimating equation was used to verify the results. PRIMARY OUTCOME MEASURE Enrolment in the pre-ESRD P4P programme. RESULTS In total, 82 991 patients were enrolled in the programme, with a 45.6% participation rate. Patients who were males (adjusted OR (AOR)=0.89, 95% CI=0.86 to 0.91) and employed (AOR=0.95, 95% CI=0.92 to 0.97) had a significantly lower probability to be enrolled in the programme. Older patients (66-75 years old, AOR=1.23, 95% CI=1.14 to 1.33) and those with higher Charlson Comorbidities Index (CCI 5+, AOR=4.01, 95% CI=3.55 to 4.53) tended to be enrolled in the programme, while those in the 76+ years age group were not (AOR=1.03, 95% CI=0.95 to 1.13). Hospitals located in the central (AOR=1.48, 95% CI=1.05 to 2.08) and Kao-Ping regions (AOR=1.62, 95% CI=1.18 to 2.22) also tended to enrol patients in the pre-ESRD P4P programme. Enrolment rates increased over time. CONCLUSION Pre-ESRD patients of the female gender, greater age and more comorbidities were more likely to be enrolled in the pre-ESRD P4P programme. Healthcare providers and health authorities should focus attention on patients who are male, younger and with less comorbidities to improve the healthcare quality and equality for all pre-ESRD patients.

Abstract
Alcohol consumption is a significant public health issue worldwide. The rat model and epidemiological studies have both reported conflicting results about the effects of alcohol on the kidneys. We aimed to explore the relationships between alcohol consumption and chronic kidney disease. Data from the National Health Interview Survey, the National Health Insurance research database, and the National Deaths Dataset were used. Standardized in-person interviews were executed in 2001, 2005, and 2009 to obtain the demographic characteristics of study population. The participants were followed up until 2013. The primary outcome was new-onset chronic kidney disease. We analyzed 45,200 adults older than 18 years (50.8% men and 49.2% women), and the overall mean (SD) age was 42.73 (16.64) years. During the 8.5 (3.5) years of follow-up, new-onset chronic kidney disease was recognized in 1535 (5.5%), 292 (2.7%), and 317 (4.9%) non-drinking, social-drinking, and regular-drinking participants, respectively. The participants who were social and regular drinkers had a significantly decreased risk of chronic kidney disease incidence (social drinking: adjusted hazard ratio (HR), 0.85; 95% confidence interval (CI), 0.74-0.97; p = 0.018; regular-drinking: AHR, 0.85; 95% CI, 0.74-0.98; p = 0.024), with baseline demographics and comorbidities adjusted. In conclusion, social and regular drinkers had decreased risk of chronic kidney disease when compared with non-drinkers.

Diabetes-related kidney, eye, and foot disease in Taiwan: An analysis of nationwide data from 2005 to 2014. J Formos Med Assoc 2019; 118 Suppl 2:S103-S110. [PMID: 31477486 DOI: 10.1016/j.jfma.2019.07.027] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2019] [Revised: 07/08/2019] [Accepted: 07/30/2019] [Indexed: 01/13/2023] Open
Abstract
BACKGROUND/PURPOSE Patients with diabetes have a higher risk of developing chronic complications and cause a huge burden to the public health care system as well as on patients and their families. We studied these diabetic complications about kidney, eye and peripheral vascular diseases to understand their prevalence and distributions in a national survey. METHODS We analyzed diabetic complications using National-Health-Insurance claims filed from 2005 to 2014. We used this database to evaluate their developments of kidney, eye, and peripheral vascular diseases according to the International-Classification-of-Diseases, Ninth Revision using clinical modification diagnosis codes. RESULTS The prevalence of diabetic kidney disease (DKD) significantly increased from 10.49% to 17.92% from 2005 to 2014. The prevalence rate of diabetic foot significantly decreased from 1.34% to 1.05% from 2005 to 2014, and the rate of severe infection also significantly decreased from 50.69% to 45.85%. The amputation rate significantly decreased from 24.91% to 17.47% among all patients with diabetic foot. CONCLUSION In this study, the trends in DKD and dialysis prevalence were similar to those of the 2012 report. The rate of increase in dialysis prevalence is lower in this study than in the 2012 report. The prevalence of diabetic foot, severe infection, and amputation in this report exhibited significantly decreasing trends. This improvement may be attributable to care from multidisciplinary teams. We should dedicate more resources to our prevention program of DKD and retinopathy to further improve outcomes in the future.

Abstract
INTRODUCTION Medical and surgical treatment options are available for patients with diabetic foot ulcers. In more severe cases, amputation decisions are determined by patient comorbidities, performance, imaging studies, and clinical examination results. However, an objective indicator that predicts how this amputation process will end has not yet been clarified. This study identifiies clinical characteristics that can be predictors of the need for diabetic foot amputation among patients. METHODS In this retrospective observational study, a total of 400 patients with type 2 diabetes who were over the age of 18 and possessed diabetic foot ulcers were examined. The clinical, radiological, and scintigraphic profiles of these patients including age, gender, duration of diabetes, smoking history, previous diabetic foot amputation, presence of hypertension (HT), coronary artery disease (CAD), peripheral artery disease (PAD), cerebrovascular disease, cardiovascular disease, retinopathy, neuropathy and nephropathy were analyzed. RESULTS Of the 400 patients with diabetic foot ulcers, 143 (35.75%) underwent foot amputation. Moreover, the frequency of proteinuria in amputees was significantly higher than in non-amputees (p<0,05). Amputees also exhibited significantly longer smoking histories (p<0,001), and the frequency of reamputation was significantly higher in those who possesed histories of previous amputation (p=0.038). After multivariate analysis PAD presence and previous diabetic ulcer history were the significant factors to determine the amputation decision. CONCLUSION The following patient characteristics were determined as being effective for predicting the need for amputation: male sex, CAD, PAD, HT, proteinuria, ulcers with Wagner Stages 4-5, smoking histories, previous diabetic ulcer histories, and previous amputation histories. The specificity of the model with these variables was determined as 86% in the patients who did not need amputation. Significant determinants were peripheral artery disease presence and diabetic foot ulcer history. Still, further and more extensive research with higher numbers of patients is necessary for determining more precisely the need for amputation.

Abstract
BACKGROUND Lower-limb amputation is one of the most substantial and debilitating consequences of diabetes mellitus; however, the risk of lower-limb amputation is not equally shared across the diabetic population. The aims of this study were to (i) describe regional variation in the rate of lower-limb amputation in New Zealand among a national prevalent cohort of patients with diabetes; and (ii) explore the plausible factors that could be contributing to this variation. METHODS Our cohort were the national prevalent cohort of individuals with diabetes in New Zealand in 2011, according to the Virtual Diabetes Register (n = 215 676). Using descriptive analysis and Poisson regression, we compared the rate of lower-limb amputation within each of New Zealand's 20 District Health Boards with the national rate of amputation, adjusting for demographic, health care access and patient-level factors. RESULTS We observed nearly four-fold variation in the rate of major lower-limb amputation between regions in New Zealand, as well as nearly two-fold variation in the rate of minor lower-limb amputation. Adjustment for differences between regions in terms of ethnicity reduced this variation substantially for many District Health Boards. Despite adjustment for sex, age, ethnicity, deprivation, rurality, comorbidity and prior amputation, the rate of lower-limb amputation in a number of District Health Boards remained substantially higher than the national rate. CONCLUSIONS These observations could help to inform the funding and provision of diabetic foot care services across New Zealand; however, more work is required to further untangle the drivers of national variation in rates of lower-limb amputation.

BMC Endocr Disord 2019; 19:27. [PMID: 30823912 PMCID: PMC6397489 DOI: 10.1186/s12902-019-0353-8] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2018] [Accepted: 02/21/2019] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND Diabetes-related lower limb amputations (LLA) are associated with significant morbidity and mortality. Although the incidence has decreased over the past two decades in most High-Income Countries, the situation in Low-Middle Income Countries (LMIC), especially those in sub-Saharan Africa (SSA) is not clear. We have determined the incidence and determinants of diabetes-related LLA in Ghana. METHODS This was a tertiary-care-based retrospective cohort study involving patients enrolled in the diabetes clinic of Komfo Anokye Teaching Hospital, Ghana from 1st January 2010 to 31st December 2015 after a median follow-up of 4.2 years. Demographic characteristics and clinical variables at baseline were recorded. The primary outcome was new diabetes-related LLA in each year under study. Cox proportional hazard regression models were used to describe the associations of diabetes-related LLA. RESULTS The mean age at enrolment for the cohort was 55.9 ± 14.6 years, with a female preponderance (62.1%). The average incidence rate of diabetes-related LLA was 2.4 (95% CI:1.84-5.61) per 1000 follow-up years: increasing from 0.6% (95% CI:0.21-2.21) per 1000 follow up years in 2010 to 10.9% (95% CI:6.22-12.44) per 1000 follow-up years in 2015. Diabetes-related LLA was associated with increased age at enrollment (for every 10 year increase in age: HR: 1.11, CI: 1.06-1.22, p < 0.001), male gender (HR: 3.50, CI:2.88-5.23, p < 0.01), type 2 diabetes (HR 3.21, CI: 2.58-10.6, p < 0.001), high Body Mass Index (HR: 3.2, CI: 2.51-7.25 p < 0.001), poor glycemic control (for a percent increase in HbA1c, HR:1.11, CI:1.05-1.25, p = 0.03), hypertension (HR:1.14, CI:1.12-3.21 p < 0.001), peripheral sensory neuropathy (HR:6.56 CI:6.21-8.52 p < 0.001) and peripheral vascular disease (HR: 7.73 CI: 4.39-9.53, p < 0.001). CONCLUSION The study confirms a high incidence of diabetes related-LLA in Ghana. Interventions aimed at addressing systemic and patient-level barriers to good vascular risk factor control and proper foot care for diabetics should be introduced in LMICs to stem the tide of the increasing incidence of LLA.

Diabetes Obes Metab 2019; 21:467-478.

Abstract
The aim of this systematic review was to examine the associations between diabetic retinopathy (DR) and the common micro- and macrovascular complications of diabetes mellitus, and how these could potentially affect clinical practice. A structured search of the PubMed database identified studies of patients with diabetes that assessed the presence or development of DR in conjunction with other vascular complications of diabetes. From 70 included studies, we found that DR is consistently associated with other complications of diabetes, with the severity of DR linked to a higher risk of the presence of, or of developing, other micro- and macrovascular complications. In particular, DR increases the likelihood of having or developing nephropathy and is also a strong predictor of stroke and cardiovascular disease, and progression of DR significantly increases this risk. Proliferative DR is a strong risk factor for peripheral arterial disease, which carries a risk of lower extremity ulceration and amputation. Additionally, our findings suggest that a patient with DR has an overall worse prognosis than a patient without DR. In conclusion, this analysis highlights the need for a coordinated and collaborative approach to patient management. Given the widespread use of DR screening programmes that can be performed outside of an ophthalmology office, and the overall cost-effectiveness of DR screening, the presence and severity of DR can be a means of identifying patients at increased risk for micro- and macrovascular complications, enabling earlier detection, referral and intervention with the aim of reducing morbidity and mortality among patients with diabetes. Healthcare professionals involved in the management of diabetes should encourage regular DR screening.

Abstract
OBJECTIVE To clarify and quantify risk factors among local characteristics of the foot for major amputation in diabetic foot patients. METHODS Articles published before January 2018 on PubMed and Embase were conducted observational studies about risk factors for major amputation in patients with diabetic foot were retrieved and systematically reviewed by using Stata 12.0 statistical software. RESULTS A total of 4668 major amputees and 65 831 controls were reported in 18 observational studies. Across the studies, the overall odds ratios (ORs) and 95% confidence intervals (CIs) of significant risk factors are ulcer reaching bone (OR, 11.796; 95% CI, 6.905-20.152), gangrene (OR, 6.487; 95% CI, 4.088-10.293), hindfoot position (OR, 3.913; 95% CI, 2.254-6.795), decreased ankle-brachial index (ABI) (OR, 2.522; 95% CI, 1.805-3.523), infection (OR, 2.516; 95% CI, 1.708-3.706), peripheral arterial disease (PAD) (OR, 2.114; 95% CI, 1.326-3.372). While there is no significant difference in the size of the ulcer, neuropathy, Charcot foot, osteomyelitis and intermittent claudication (OR, 1.15; 95% CI, 0.85-1.54). CONCLUSION Factors among local characteristics of the foot associated with major amputation in patients with diabetic foot are the ulcer reaching bone, gangrene, hindfoot position, decreased ABI, infection, and PAD, a negative risk factor for the risk of amputation. Further studies are required to provide more details of foot local characteristics.

Abstract
Patients with diabetes are at a high risk of lower extremity amputations and may have a reduced life expectancy. Taiwan has implemented a diabetes pay-for-performance (P4P) program providing team care to improve the control of disease and avoid subsequent complications. Few studies investigated the effects of adopting a nationalized policy to decrease amputation risk in diabetes previously. Our study aimed to analyze the impact of the P4P programs on the incidence of lower extremity amputations in Taiwanese patients with diabetes.This was a population-based cohort study using the Taiwan National Health Insurance Research Database (which provided coverage for 98% of the total population in Taiwan) from 1998 to 2007. Patients with diabetes were identified based on the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnostic codes. We linked procedure codes to inpatient claims to identify patients hospitalized for nontraumatic lower extremity amputations.A total of 9738 patients with diabetes with amputations were enrolled (mean age ± standard deviation: 64.4 ± 14.5 years; men: 63.9%). The incidence of nontraumatic diabetic lower extremity amputations decreased over the time period studied (3.79-2.27 per 1000 persons with diabetes). Based on the Cox proportional hazard regression model, male sex (hazard ratio: 1.83, 95% confidence interval [CI] 1.76-1.92), older age, and low socioeconomic status significantly interact with diabetes with respect to the risks of amputation. Patients who did not join the P4P program for diabetes care had a 3.46-fold higher risk of amputation compared with those who joined (95% CI 3.19-3.76).The amputation rate in Taiwanese diabetic patients decreased over the time period observed. Diabetes in patients with low socioeconomic status is associated with an increased risk of amputations. Our findings suggested that in addition to medical interventions and self-management educations, formulate and implement of medical policies, such as P4P program, might have a significant effect on decreasing the diabetes-related amputation rate.

Abstract
AIMS To examine the incidence of amputation in patients with type 2 diabetes mellitus (T2DM) treated with sodium glucose co-transporter 2 (SGLT2) inhibitors overall, and canagliflozin specifically, compared with non-SGLT2 inhibitor antihyperglycaemic agents (AHAs). MATERIALS AND METHODS Patients with T2DM newly exposed to SGLT2 inhibitors or non-SGLT2 inhibitor AHAs were identified using the Truven MarketScan database. The incidence of below-knee lower extremity (BKLE) amputation was calculated for patients treated with SGLT2 inhibitors, canagliflozin, or non-SGLT2 inhibitor AHAs. Patients newly exposed to canagliflozin and non-SGLT2 inhibitor AHAs were matched 1:1 on propensity scores, and a Cox proportional hazards model was used for comparative analysis. Negative controls (outcomes not believed to be associated with any AHA) were used to calibrate P values. RESULTS Between April 1, 2013 and October 31, 2016, 118 018 new users of SGLT2 inhibitors, including 73 024 of canagliflozin, and 226 623 new users of non-SGLT2 inhibitor AHAs were identified. The crude incidence rates of BKLE amputation were 1.22, 1.26 and 1.87 events per 1000 person-years with SGLT2 inhibitors, canagliflozin and non-SGLT2 inhibitor AHAs, respectively. For the comparative analysis, 63 845 new users of canagliflozin were matched with 63 845 new users of non-SGLT2 inhibitor AHAs, resulting in well-balanced baseline covariates. The incidence rates of BKLE amputation were 1.18 and 1.12 events per 1000 person-years with canagliflozin and non-SGLT2 inhibitor AHAs, respectively; the hazard ratio was 0.98 (95% confidence interval 0.68-1.41; P = .92, calibrated P = .95). CONCLUSIONS This real-world study observed no evidence of increased risk of BKLE amputation for new users of canagliflozin compared with non-SGLT2 inhibitor AHAs in a broad population of patients with T2DM.

Abstract
AIMS/HYPOTHESIS Lower limb amputation is a serious complication of diabetes mellitus. Understanding how amputation risk differs by population subgroups is crucial in terms of directing preventive strategies. In this study, we describe those factors that impact amputation risk in the entire prevalent diabetic population of New Zealand. METHODS A national prevalent cohort of 217,207 individuals with diabetes in 2010 were followed up until the end of 2013 for lower limb amputations, and 2014 for mortality. Inpatient hospitalisation data were used to define lower limb amputation using ICD-10 codes. Cox proportional hazards models were used to describe relative hazard of amputation over the follow-up period. RESULTS A total of 784 individuals (3.6 cases/1000 individuals) underwent a major (above-ankle) lower limb amputation during follow-up, while 1217 (5.6/1000) underwent a minor (below ankle) amputation. The risk of major and minor amputation was 39% and 77% greater for men than women, respectively (adjusted HR: major amputation 1.39, 95% CI 1.20, 1.61; minor amputation 1.77, 95% CI 1.56, 2.00). Indigenous Māori were at 65% greater risk of above-knee amputation compared with the European/Other diabetic population (HR 1.65, 95% CI 1.37, 1.97). Amputation risk increased with increasing comorbidity burden, and peripheral vascular disease conferred the greatest independent risk of all comorbid conditions. Prior minor amputation increased the risk of subsequent major amputation by tenfold (HR 10.04, 95% CI 7.83, 12.87), and increased the risk of another minor amputation by 20-fold (HR 21.39, 95% CI 17.89, 25.57). Death was common among the total cohort, but particularly among those who underwent amputation, with more than half of those who underwent a major amputation dying within 3 years of their procedure (57%). CONCLUSIONS/INTERPRETATION Using a large, well-defined, national prevalent cohort of people with diabetes, we found that being male, indigenous Māori, living in deprivation, having a high comorbidity burden and/or having a previous amputation were strongly associated with subsequent risk of lower limb amputation. The use of this prevalent cohort strengthens the value of our estimates in terms of applicability to the general population, and highlights the subgroups at greatest risk of lower limb amputation.

A systematic review describing incidence rate and prevalence of dysvascular partial foot amputation; how both have changed over time and compare to transtibial amputation. Syst Rev 2017; 6:230.

Abstract
BACKGROUND Partial foot amputation (PFA) is a common consequence of advanced peripheral vascular disease. Given the different ways incidence rate and prevalence data have been measured and reported, it is difficult to synthesize data and reconcile variation between studies. As such, there is uncertainty in whether the incidence rates and prevalence of PFA have increased over time compared to the decline in transtibial amputation (TTA). The aims of this systematic review were to describe the incidence rate and prevalence of dysvascular PFA over time, and how these compare to TTA. METHOD Databases (i.e., MEDLINE, EMBASE, psychINFO, AMED, CINAHL, ProQuest Nursing and Allied Health) were searched using MeSH terms and keywords related to amputation level and incidence rate or prevalence. Original research published in English from 1 January 2000 to 31 December 2015 were independently appraised, and data extracted, by two reviewers. The McMaster Critical Review Forms were used to assess methodological quality and bias. Results were reported as narrative summaries given heterogeneity of the literature and included the weighted mean annual incidence rate and 95% confidence interval. RESULTS Twenty two cohort studies met the inclusion criteria. Twenty one reported incidence rate data for some level of PFA; four also included a TTA cohort. One study reported prevalence data for a cohort with toe(s) amputation. Samples were typically older, male and included people with diabetes among other comorbidities. Incidence rates were reported using a myriad of denominators and strata such as diabetes type or initial/recurrent amputation. CONCLUSION When appropriately grouped by denominator and strata, incidence rates were more homogenous than might be expected. Variation between studies did not necessarily reduce confidence in the conclusion; for example, incidence rate of PFA were many times larger in cohorts with diabetes (94.24 per 100,000 people with diabetes; 95% CI 55.50 to 133.00) compared to those without (3.80 per 100,000 people without diabetes; 95% CI 1.43 to 6.16). It is unclear whether the incidence rates of PFA have changed over time or how they have changed relative to TTA. Further research requires datasets that include a large number of amputations each year and lengthy time periods to determine whether small annual changes in incidence rates have a cumulative and statistically significant effect over time.

Abstract
BACKGROUND AND AIMS Increased body fat relates to enhanced inflammatory cytokine production, which, in turn, activates the renin-angiotensin-aldosterone system and increases the risk of chronic kidney disease (CKD). Herein, we aimed to examine the association between obesity and the risk of CKD in a population-representative cohort in Taiwan. METHODS AND RESULTS A multistage systematic sampling process was applied in the National Health Interview Survey (NHIS) 2000, 2005, and 2009. Participants were interviewed by a standardized face-to-face questionnaire to obtain information on their demographics, socioeconomic status, lifestyle factors, and body mass index (BMI). The BMI values were classified as follows: underweight (<18.5 kg/m2), normal (18.5-23.9 kg/m2), overweight (24-26.9 kg/m2), and obesity (≥27 kg/m2). The NHIS dataset was linked to National Health Insurance claims data to identify the incidence of CKD. Univariate and multivariate Cox proportional hazard models with competing risks were used to investigate the association between BMI and CKD incidence. We analyzed 45,012 subjects (mean age, 42.03 years; 50.09% males). During 374,254 person-years of follow-up, a total of 1913 new-onset CKD cases were identified. Kaplan-Meier curves comparing the four BMI groups revealed a significant difference (p < 0.01, log-rank test). After controlling for confounding factors, the relative risk of incident CKD was significantly higher in the obese group compared to the normal-weight group (adjusted hazard ratio = 1.32; 95% confidence interval: 1.17-1.49), with a significant linear trend (p < 0.01). CONCLUSION Obesity was suggested as an independent risk factor for CKD. Further studies focusing on the effect of losing weight on CKD prevention are warranted.

Abstract
Amputation of patients with diabetic foot is a major issue worldwide, particularly from a medical and economic standpoint. This meta-analysis aimed to identify significant risk factors of high amputation rate among epidemiologic and patient behavior–related predictors in diabetic patients. A systematic literature review and meta-analysis were performed using MEDLINE, EMBASE, and Cochrane databases. Seven variables were extracted from the included studies and evaluated based on amputation rate. The Newcastle-Ottawa scale was used to assess the quality of the studies. The search strategy identified 101 publications. After screening, 33 articles were selected for review. Male sex and smoking were identified as significant risk factors of high amputation rate of diabetic foot. Although further investigation of long-term and randomized controlled studies is needed, we identified 2 variables as significant risk factors for high amputation rate in diabetic patients in this meta-analysis.

Abstract
Early detection and treatment of lower extremity atherosclerotic disease (LEAD), and controlling its risk factors are critical in preventing amputation and death in diabetic patients. This study aimed to investigate the factors associated with LEAD in Chinese diabetic patients.In this case-control study, patients with type 2 diabetes mellitus (T2DM) (N = 1289) were divided into 2 groups according to the ultrasonic Doppler examination: with (LEAD+, n = 737) and without (LEAD-, n = 552) LEAD. In subgroup analysis, the LEAD+ group was divided based on the diameter of lower-extremity arteries: LEAD+A (1%-49% reduction) and LEAD+B (≥50% reduction). Clinical and demographic data of patients were analyzed.Compared with the LEAD- group, serum creatinine levels were significantly increased (P < 0.001), whereas glomerular filtration rate (GFR) was significantly decreased (P < 0.001) in the LEAD+ group. Multivariate analysis results showed that GFR (odds ratio [OR] 0.991, 95% confidence interval [CI] 0.986-0.997, P = 0.003), diabetes duration (OR 1.055, 95% CI 1.026-1.084, P < 0.001), age (OR 1.123, 95% CI 1.104-1.142, P < 0.001), and uric acid (OR 1.002, 95% CI 1.000-1.004, P = 0.031) were independently associated with LEAD in patients with T2DM. Furthermore, multivariate analysis showed that age (OR 1.078, 95% CI 1.048-1.109, P < 0.001) and GFR (OR 0.985, 95% CI 0.975-0.994, P = 0.002) were independently associated with the severity of arterial lesions in patients with T2DM and LEAD.The risk factors of LEAD in Chinese patients with T2DM include age, course of disease, uric acid, and GFR. Patients with T2DM, high uric acid levels, and declined GFR could be listed in the high-risk group for LEAD.

Abstract
The estimated prevalence of diabetes is 9.78% in Taiwan. The lifetime risk for patients with diabetes to have foot ulcers might be as high as 25%. About 15% of these patients require major limb amputation because of ischemia and infection. Peripheral artery disease is still a major problem involved in diabetic foot disease and the cause for major amputation despite an increase in the prevalence of revascularization surgery and new revascularization techniques over the past 20 years. We investigated the major limb amputation rates in patients with diabetic foot and critical limb ischemia who had undergone revascularization surgery in our hospital. The records of 42 patients who had undergone revascularization surgery for diabetic foot were retrospectively reviewed. Nineteen patients (45%) required major limb amputation despite revascularization. The affected limbs of only 15 patients (36%) were salvaged. Four patients died soon after surgery because of comorbidities, and another 4 were lost to follow-up. Two patients died from procedure-related sepsis, and overall perioperative mortality was 4.8%. Ten predictive risk factors (duration of diabetes, history of smoking, coronary artery disease, congestive heart failure, cerebral vascular accident, contralateral amputation, end-stage renal disease, fever episode, wound infection severity score, and arterial obstruction level) were included for analysis. Although none was significant, long-duration diabetes (OR: 1.13), end-stage renal disease (OR: 10.02), wound infection (OR: 1.56), and infrapopliteal lesions (OR: 3.00) tended to be unfavorable predictive risk factors of limb amputation. Revascularization surgery is still potentially beneficial for these patients--eg, it decreases the contralateral limb amputation rate by 7.5%--if done early in high-risk patients.

Abstract
We evaluated the effects of diabetes on the risks of developing deep-vein thrombosis (DVT) and pulmonary embolism (PE) in a nationwide, population-based cohort study in Taiwan. The patients with newly diagnosed type 2 diabetes mellitus (T2DM) were identified, and DM-free controls were randomly selected from the general population and frequency-matched according to age, sex, and index year by using the records of the Longitudinal Health Insurance Database between 2000 and 2011. Both cohorts were followed up until the end of 2011 to measure the incidence of DVT and PE. We analysed the risks of DVT and PE using Cox proportional-hazards regression models. The overall incidence of VTE was higher in the T2DM patients than in the controls (12.0 vs 7.51 per 10,000 person-years). The T2DM patients exhibited a 1.44-fold adjusted hazard ratio (aHR) of VTE development compared with the controls (95% confidence interval [CI] = 1.27-1.63). The risks of DVT (aHR = 1.43, 95% CI = 1.23-1.65) and PE (aHR = 1.52, 95% CI = 1.22-1.90) were greater in the T2DM than those in the controls. The T2DM patients had a substantially higher risk of DVT (aHR = 5.10, 95% CI = 3.12-8.32) and PE (aHR = 7.50, 95% CI = 3.29-17.1) development than the controls did in adults aged 49 years and younger. In conclusion, the longitudinal nationwide cohort study indicated that T2DM patients carried greater risks of developing VTE than did the general population.
