Abstract
Background The COVID-19 pandemic necessitated changes in processes of care, which significantly impacted surgical care. This study evaluated the impact of these changes on patient outcomes and costs for non-elective major lower extremity amputations (LEA). Methods The 2019-2021 Florida Agency for Health Care Administration database was queried for adult patients who underwent non-elective major LEA. Per-patient inflation-adjusted costs were collected. Patient cohorts were established based on Florida COVID-19 mortality rates: COVID-heavy (CH) included nine months with the highest mortality, COVID-light (CL) included nine months with the lowest mortality, and pre-COVID (PC) included nine months before COVID (2019). Outcomes included in-hospital patient outcomes and hospitalization cost. Results 6132 patients were included (1957 PC, 2104 CH, and 2071 CL). Compared to PC, there was increased patient acuity at presentation, but morbidity (31%), mortality (4%), and length of stay (median 12 [8-17] days) were unchanged during CH and CL. Additionally, costs significantly increased during the pandemic; median total cost rose 9%, room costs increased by 16%, ICU costs rose by 15%, and operating room costs rose by 15%. When COVID-positive patients were excluded, cost of care was still significantly higher during CH and CL. Conclusions Despite maintaining pre-pandemic standards, as evidenced by unchanged outcomes, the pandemic led to increased costs for patients undergoing non-elective major LEA. This was likely due to increased patient acuity, resource strain, and supply chain shortages during the pandemic. Key message While patient outcomes for non-elective major lower extremity amputations remained consistent during the COVID-19 pandemic, healthcare costs significantly increased, likely due to increased patient acuity and heightened pressures on resources and supply chains. These findings underscore the need for informed policy changes to mitigate the financial impact on patients and healthcare systems for future public health emergencies.

Abstract
AIMS To compare the medical costs of individuals undergoing lower extremity amputation (LEA) in Belgium with those of amputation-free individuals. METHODS Belgian citizens undergoing LEAs in 2014 were identified. The median costs per capita in euros for the 12 months preceding and following minor and major LEAs were compared with those of matched amputation-free individuals. RESULTS A total of 3324 Belgian citizens underwent LEAs (2295 minor, 1029 major), 2130 of them had diabetes. The comparison group included 31,716 individuals. Amputation was associated with high medical costs (individuals with diabetes: major LEA €49,735, minor LEA €24,243, no LEA €2,877 in the year preceding amputation; €45,740, €21,445 and €2,284, respectively, in the post-amputation year). Significantly higher costs were observed in the individuals with (versus without) diabetes in all groups. This difference diminished with higher amputation levels. Individuals undergoing multiple LEAs generated higher costs (individuals with diabetes: €39,313-€89,563 when LEAs preceded index amputation; €46,629-€92,877 when LEAs followed index amputation). Individuals dying in the year after a major LEA generated remarkably lower costs. CONCLUSIONS LEA-related medical costs were high. Diabetes significantly impacted costs, but differences in costs diminished with higher amputation levels. Individuals with multiple amputations generated the highest costs.

Abstract
OBJECTIVE Lower extremity amputations are a major complication of diabetes mellitus (DM). In a previous Dutch study, the incident rate of major amputations was 89.2 per 100 000 person years. The primary aim of this study was to describe the lower extremity amputation rates in people with DM in the Zwolle region, where preventive and curative footcare is organised according to the guidelines of the International Working Group of the Diabetic Foot (IWGDF). The secondary aim was to evaluate outcomes and underlying characteristics of these people. METHODS This was a retrospective regional population based cohort study. Data from all people with DM treated in primary and secondary care, living in the region Zwolle were collected. All amputations in the period 2017 to 2019 were analysed. Comparisons were made between those with and without an amputation. RESULTS In the analysis 5 915 people with DM were included, with a mean age of 67.8 (IQR 57.9, 75.9) years. Of those people, 47% were women and the median HbA1c was 53 (IQR 47, 62) mmol/mol. Over the three year study period 68 amputations were performed in 59 people: 46 minor, 22 major. This translated into an average annual crude amputation incidence rate of non-traumatic major and minor amputations of 41.5 and 86.9 per 100 000 person years among people with diabetes. Compared with those not undergoing amputations, those who underwent an amputation were more often men, older, mainly had T2DM, were treated in secondary care, had higher diastolic blood pressure, worse diabetic footcare profile, longer DM duration and higher HbA1c. At the end of the follow up, 111 people died: 96 (1.6%) without and 15 (25.4%) with amputations (p < .001). CONCLUSIONS This retrospective study provides detailed insight into the rate of amputations in Dutch people with diabetes in the region Zwolle. Compared with previous Dutch estimates, these data suggest a considerable decrease in the major amputation incidence rate.

Abstract
Diabetes-related foot disease (DFD) is a widely feared complication among people who live with diabetes. In Australia and globally, rates of disability, cardio-vascular disease, lower extremity amputation, and mortality are significantly increased in patients with DFD. In order to understand and prevent these outcomes, we analyse the common pathogenetic processes of neuropathy, arterial disease, and infection. The review then summarises important management considerations through the interdisciplinary lens. Using Australian and international guidelines, we offer a stepwise, evidence-based practical approach to the care of patients with DFD.

Abstract
BACKGROUND Reamputation as a complication of diabetic foot ulcers presents a high economic burden and represents a therapeutic failure. It is paramount to identify as early as possible patients in whom a minor amputation may not be the best option. The purpose of this investigation was to do a case-controlled study to determine risk factors associated with re-amputation in patients with DFU (diabetic foot ulcers) at two University Hospitals. METHODS Multicentric, observational, retrospective, case-control study from clinical records of 2 university hospitals. Our study included 420 patients, with 171 cases (re-amputations), and 249 controls. We performed a multivariate logistic regression analysis and time-to-event survival analysis to identify re-amputation risk factors. RESULTS Statistically significant risk factors were artery history of tobacco use (p = 0.001); male sex (p = 0.048); arterial occlusion in Doppler ultrasound (p = 0.001); percentage of stenosis in arterial ultrasound >50 % (p = 0.053); requirement of vascular intervention (p = 0.01); and microvascular involvement in photoplethysmography (p = 0.033). The most parsimonious regression model suggests that history of tobacco use, male sex, arterial occlusion in ultrasound, and percentage of stenosis in arterial ultrasound >50 % remained statistically significant. The survival analysis identified earlier amputations in patients with larger occlusion in arterial ultrasound, high leukocyte count, and elevated ESR. CONCLUSION Direct and surrogate outcomes in patients with diabetic foot ulcers identify vascular involvement as an important risk factor for reamputation. LEVEL OF EVIDENCE III.

Abstract
Introduction the study aimed to outline the common indications and complications of lower extremity amputations among amputated patients in two tertiary hospitals in the North West Region of Cameroon. Methods this hospital based retrospective study was conducted in the Bamenda Regional Hospital and Mbingo Baptist Hospital over a 5-year period from 2015-2019. We identified and reviewed amputee´s medical records over the 5-year period. A well designed extraction form was used for data collection and the data obtained was analysed using Epi-info version 7.2.4. Results a total of 148 patients underwent 159 amputations in Bamenda Regional Hospital and Mbingo Baptist Hospital with a mean age of 54.28 years (SD ±19.28). Males out-numbered females with a ratio of 2: 1. The most common indication for lower extremity amputation was Diabetic foot gangrene (42.14%) followed by trauma (22.01%). The most frequently performed procedure was Below Knee Amputation (48.42%). Post-amputation complication rate was recorded at 40.25% with surgical site infection being the most common (25.8%). Mortality rate was recorded at 6.28%. Conclusion diabetic foot gangrene is the leading indication of lower limb amputation in our setting and the most frequently performed procedure is Below Knee Amputation with surgical site infection being the most common complication.

Abstract
Racial, ethnic, socioeconomic, and geographic disparities in limb preservation and nontraumatic lower extremity amputation (LEA) are consistently demonstrated in populations with diabetes and peripheral artery disease (PAD). Higher rates of major LEA in disadvantaged groups are associated with increased health care utilization and higher costs of care. Functional decline that often follows major LEA confers substantial risk of disability and premature mortality, and the burden of these outcomes is more prevalent in racial and ethnic minority groups, people with low socioeconomic status, and people in geographic regions where limited resources or distance from specialty care are barriers to access. We present a narrative review of the existing literature on estimated costs of diabetic foot disease and PAD, inequalities in care that contribute to excess costs, and disparities in outcomes that lead to a disproportionate burden of diabetes- and PAD-related LEA on systematically disadvantaged populations.

Abstract
Major nontraumatic lower extremity amputation (LEA) is a morbid complication of longstanding or poorly controlled diabetes and/or end-stage peripheral artery disease. Incidence of major LEAs consistently declined during the 1990s and 2000s, but rates have plateaued or increased in many regions during the past decade. Marked racial, ethnic, socioeconomic, and geographic disparities in risk of LEA persist and are related to inequalities in access to care and differential rates of attempted limb preservation. Multidisciplinary diabetic foot care (MDFC) is increasingly recognized as a necessary model for optimal management of patients with diabetic foot and vascular disease. This article reviews the role of MDFC in reducing major LEAs and the specific ways in which MDFC can mitigate disparities in care delivery and limb preservation outcomes. Access to MDFC among vulnerable populations remains a significant barrier to systematic reduction in major LEAs.

Abstract
BACKGROUND Lower extremity amputations (LEAs) as a result of type 2 diabetes mellitus (T2DM) cause considerable morbidity, mortality, and burden on the healthcare system. LEAs are thought to be preventable, yet the rate of LEAs, particularly in Australia, has risen despite the availability of preventative healthcare services. Understanding patient's perspectives of risk factors for LEAs may provide valuable insight into why many LEAs occur each year. OBJECTIVE The aim of this study was to explore patient's perspectives of risk factors for LEAs as a result of T2DM. METHODS A qualitative descriptive methodology involving non-probability purposive sampling was used to recruit inpatients at a tertiary metropolitan hospital in South Australia. Semi-structured interviews were conducted, and data were transcribed verbatim. Data from the interviews were analysed using thematic analysis and the constant comparison approach. RESULTS A total of 15 participants shared their perspectives of risk factors for lower extremity amputations. Most (86%) of participants were male and Caucasian, with a median age of 66.4 years ranging from 44-80 years. The median duration of diabetes was 25.2 years, ranging from 12-40 years. More than half of the participants had undergone a previous amputation with 86% being unemployed or retired and 73% living in metropolitan Adelaide. Two main themes emerged: competing priorities and awareness. Finance and family care were identified as subthemes within competing priorities. While subthemes in the context of awareness related to lack of awareness of risk, experiences with health care professionals and perspectives of disease severity. CONCLUSIONS The findings from this research indicate that addressing risk factors for LEAs for patients with T2DM require a holistic and nuanced approach which considers individual patient's circumstances, and its influence on how risks are viewed and managed.

Abstract
OBJECTIVES To investigate the risk factors of lower limb amputation, and help physicians better understand the clinical characteristics of patients with diabetic foot, and make treatment strategies for these patients correctly. METHODS In this study, the inpatients with diabetic foot treated in our hospital form January 2013 to February 2021 were reviewed retrospectively. The patients were divided into amputation and conservative treatment groups. The variables of the patients, consisting of age, gender, smoking history, alcohol use, diabetes and ulcer duration, ulcer size, Wagner classification, ankle brachial index, previous amputation history, laboratory data, and medical comorbidities including hypertension, coronary artery disease, peripheral arterial disease, chronic renal insufficiency, retinopathy, and sequelae of cerebral infarction were selected for analysis to determine the risk factors of lower limb amputation. RESULTS In this study, a total of 856 patients with diabetic foot were enrolled, in which 487 patients received amputation surgeries, and the amputation rate was 56.9%. There were significant differences between the two groups in gender (p=0.014), smoking history (p=0.011), ulcer duration (p=0.023), ulcer size (p=0.000), Wagner classification (p=0.000), ABI (p=0.031), peripheral arterial disease (p=0.000), HDL-C (p=0.013), osteomyelitis (p=0.000), and fibrinogen (p=0.001). A stepwise multiple logistic regression analysis revealed that male gender (p=0.003), larger ulcer size (p=0.001), higher Wagner classification grades (p=0.002), higher rate of peripheral arterial disease (p=0.02) and osteomyelitis (p=0.0001), and increased fibrinogen level (p=0.004) were independent risk factors of lower limb amputation in patients with diabetic foot. CONCLUSION The diabetic foot patients with male sex, larger ulcer size, higher grade of Wagner classification, peripheral arterial disease or higher fibrinogen level may face higher risk of lower limb amputation.

Abstract
AIMS To assess trends in hospital admissions for non-traumatic lower extremity amputations (LEAs) and for mortality following LEAs in adult patients with type 1 diabetes (T1DM) or type 2 diabetes (T2DM) admitted to hospitals in Victoria, Australia during 2004-2016. METHODS Using hospital discharge data, we calculated age- and sex- adjusted admission rates for incident cases of any LEA, minor LEAs, major LEAs and 12-month mortality following any LEAs for patients according to diabetes type. Joinpoint regression analysis was used to identify changes in linear trends that were described as average annual percentage change (AAPC). RESULTS Significant declines in rates of admission for any LEA (AAPC -4.9), minor LEAs (-3.0 %) and major LEAs (AAPC -11.5 %) were seen for patients with T2DM. Overall, admission rates for any LEA did not significantly change for patients with T1DM during 2004 and 2016, however, we detected a significant rise in admissions for any LEAs (AAPC +5.1) in female patients with T1DM. This increase was most prominent in younger (<60 years) patients undergoing minor LEAs. During 2009-2016, younger patients with type 1 DM, regardless of sex, also experienced significant increases in admissions for any LEA (AAPC +14) and major LEAs (AAPC +15). Mortality associated with LEAs in T2DM declines, with a 12-month mortality rate of 6.3 %) associated with LEAs in T2M decline (AAPC -4.2 %) whereas rates for T1DM remained stable (1.9 %) during 2004-2016. CONCLUSIONS There were significant differences in LEA hospital admission trends by type of diabetes, age and sex. The decline in LEAs and its associated mortality is welcome news for patients with T2DM. However, reasons for the increase in LEAs in younger patients with T1DM remain to be determined.

Abstract
AIMS This study assessed temporal trends in the incidence of lower extremity amputations (LEA) in Belgium from 2009 to 2018, and subsequent secondary amputation rates. METHODS Nationwide data on LEA were collected. Sex- and age-adjusted annual incidence rates were calculated. Time trends were analysed in negative binomial models. The incidence of secondary interventions, defined as either any ipsilateral reamputation or any contralateral amputation, was studied with death as competing risk. RESULTS 41 304 amputations were performed (13 247 major, 28 057 minor). In individuals with diabetes, the amputation rate (first amputation per patient per year) decreased from 143.6/100.000 person-years to 109.7 (IRR 0.97 per year, 95 %CI 0.96-0.98, p < 0.001). The incidence of major LEAs decreased from 56.2 to 30.7 (IRR 0.93, 95 %CI 0.91-0.94, p < 0.001); the incidence of minor amputations showed a non-significant declining trend in women (54.3 to 45.0/100 000 person years, IRR 0.97 per year, 95 %CI 0.96-0.99), while this remained stable in men with diabetes (149.2 to 135.3/100 000 person years, IRR 1.00 per year, 95 %CI 0.98-1.01). In individuals without diabetes, the incidence of major amputation didn't change significantly, whereas minor amputation incidence increased (8.0 to 10.6, IRR 1.04, 95 %CI 1.03-1.05, p < 0.001). In individuals with diabetes, one-year secondary intervention rates were high (31.3% after minor, 18.4% after major LEA); the incidence of secondary amputations didn't change. CONCLUSIONS A significant decline in the incidence rate of major LEA was observed in people with diabetes. This decline was not accompanied by a significant rise in minor LEA. The incidence of secondary interventions remained stable.

Abstract
BACKGROUND It is well-known that exercise through sports and physical activity has beneficial effects on health. After lower extremity amputation, low rates of participation in sports activities have been shown. So far, there is only limited scientific long-term information concerning sports activity and feasible types of sports in patients with lower extremity amputations due to malignant tumors. This study sought to provide very long-term information about the following questions: (1) What sports activity levels can be achieved after lower extremity amputation due to a malignant tumor? (2) What are feasible types of sports? (3) Is the University of California Los Angeles (UCLA) Activity Score influenced by patient's age, the age at the time of surgery and the amount of prosthesis sockets used to date? HYPOTHESIS Patients with lower extremity amputation due to a malignant tumor cannot regularly participate in moderate sports activities (UCLA Activity Score≥6) in the very long-term. MATERIALS AND METHODS In a retrospective questionnaire survey, 21 former patients (seven females, 14 males; median age: 60.5years [range: 33-74]) who underwent an amputation of the lower extremity (14 transfemoral, four knee disarticulations, three transtibial) from 1961 to 1993 due to a malignant tumor were interviewed. The median follow-up was 41.1years (range: 23-55). The patients were interviewed about types of sports, frequencies and durations of sports sessions at the time of the last follow-up, as well as retrospectively. Sports activity levels were then assessed based on the UCLA Activity Score. Demographic background, data on amputation level, histological results, prosthetic devices and revision surgeries were collected. RESULTS Seven patients (33%) were still regularly exercising at least moderate sports activities at the last follow-up, including one patient regularly participating in impact sports. The preoperative median UCLA Activity Score of 9 (range: 2-10) decreased to 5 (range: 2-10) at the last follow-up (p<0.001). Swimming (13 patients, seven on a regular basis), cycling (seven), downhill skiing (five) and hiking (four) were among the most common feasible types of sports. Increasing age had a negative influence on the UCLA Activity Score [95% CI (-0.034, -0.006); RB=-0.020; SD=0.0074; p=0.007]. CONCLUSION After a major amputation in the lower extremity due to a malignant tumor, high activity levels by practicing types of sports such as downhill skiing, are achievable. In the very long-term, a regular participation in at least moderate activities, such as swimming, is possible. Programs for physical and sports activities, based on recommendations drawn from long-term experience, are necessary and should be individually tailored to amputees and their limitations.

Abstract
INTRODUCTION More than 52.4% of people with a lower extremity amputation (PLEA) will fall at least once each year. Previously established standardized scales which evaluate a concern for falling (CFF) were primarily developed among community dwelling older adults. The reliability of commonly used scales to evaluate a CFF among PLEA is needed. OBJECTIVE To evaluate test-retest relative and absolute reliability, and agreement of the Modified Survey of Activities and Fear of Falling in the Elderly (mSAFFE), Falls Efficacy Scale - International (FES-I), Consequences of Falling (COF) Scale, Perceived Control Over Falling (PCOF) Scale, and Perceived Ability to Manage Falls (PAMF) Scale among PLEA. DESIGN Web-based cross-sectional repeated measures study. SETTING Rehabilitation hospital. PARTICIPANTS Regularly scheduled appointments (N = 22, mean age ± SD, 63.5 ± 12.9 years) with a transtibial or transfemoral level amputation, completed a prosthetic rehabilitation program, and at minimum of one year using a prosthesis for ambulation. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE(S) Initial and re-test scores on the mSAFFE, FES-I, COF, PAMF, and PCOF. RESULTS Intraclass correlation coefficients (ICC) demonstrated excellent relative reliability of the mSAFFE [ICC = 0.92 (95% CI: 0.82-0.97)], good relative reliability of the FES-I [ICC = 0.87 (95% CI: 0.70-0.94)], and fair relative reliability of the COF [ICC = 0.78 (95% CI: 0.53-0.90)] and PAMF [ICC = 0.73 (95% CI: 0.46-0.88)] scales. The ICC value of the PCOF scale could not be validly calculated and was not further analyzed. Calculated SE of measurement values for the mSAFFE, FES-I, COF, and PAMF scales were small in magnitude and Bland-Altman graphs demonstrated good agreement of initial and re-test scores for all scales. CONCLUSION This study provides initial evidence on the suitability and reliable use of the mSAFFE, FES-I, COF, and PAMF scales within this population. Further evaluation of the validity of these scales is needed. This article is protected by copyright. All rights reserved.

Abstract
OBJECTIVE Prediction of amputation wound healing is challenging due to the multifactorial nature of critical limb ischemia and lack of objective assessment tools. Up to one-third of amputations require revision to a more proximal level within 1 year. We tested a novel wound imaging system to predict amputation wound healing at initial evaluation. METHODS Patients planned to undergo amputation due to critical limb ischemia were prospectively enrolled. Clinicians evaluated the patients in traditional fashion, and all clinical decisions for amputation level were determined by the clinician's judgement. Multispectral images of the lower extremity were obtained preoperatively using a novel wound imaging system. Clinicians were blinded to the machine analysis. A standardized wound healing assessment was performed on postoperative day 30 by physical exam to determine whether the amputation site achieved complete healing. If operative revision or higher level of amputation was required, this was undertaken based solely upon the provider's clinical judgement. A machine learning algorithm combining the multispectral imaging data with patient clinical risk factors was trained and tested using cross-validation to measure the wound imaging system's accuracy of predicting amputation wound healing. RESULTS A total of 22 patients undergoing 25 amputations (10 toe, five transmetatarsal, eight below-knee, and two above-knee amputations) were enrolled. Eleven amputations (44%) were non-healing after 30 days. The machine learning algorithm had 91% sensitivity and 86% specificity for prediction of non-healing amputation sites (area under curve, 0.89). CONCLUSIONS This pilot study suggests that a machine learning algorithm combining multispectral wound imaging with patient clinical risk factors may improve prediction of amputation wound healing and therefore decrease the need for reoperation and incidence of delayed healing. We propose that this, in turn, may offer significant cost savings to the patient and health system in addition to decreasing length of stay for patients.

Abstract
OBJECTIVE Population level data from Asia on amputation rates in people with and without diabetes are extremely limited. Hence it is unclear how the rising diabetes prevalence in Asia has affected the amputation burden. The present study examined national amputation rates in people with and without diabetes in Singapore from 2008 to 2017 in the context of increasing diabetes prevalence and health system changes. METHODS This was a retrospective observational study using national population data for ages 16 - 100 years obtained from the Ministry of Health Singapore administrative datasets. Age sex standardised major and toe/ray amputation rates per 100 000 people with diabetes and per 100 000 people without diabetes were calculated. Rates were calculated overall and in each ethnic group (Chinese, Malay, Indian, Others), with trends over time calculated using joinpoint trend analysis. In addition, age specific rates, relative risk (RR) of amputation in diabetics compared with non-diabetics and proportion of amputations in the population attributable to diabetes were also calculated. RESULTS Between 2008 and 2017, the database included 3.6 million unique individuals, of whom 75% were Chinese, 8.6% Malay, 7.9% Indian, and 8.4% Others. Of those, 413 486 (11%) had diabetes. Major amputation rates in people with diabetes remained stable (2008: 99.5/100 000; 2017: 95.0/100 000 people with diabetes, p = .91) as did toe/ray amputation rates. Rates in people without diabetes were substantially lower, with major amputation rates decreasing significantly (2008: 3.0/100 000; 2017: 2.1/100 000 people without diabetes, 3% annual reduction, p = .048). Diabetes related amputation rates were highest in Malays and lowest in Chinese. Diabetes related major amputation rates declined significantly among Chinese (3.1% annual reduction, p < .038). While the RR for amputations in diabetes remained stable, the proportion of major amputations attributable to diabetes increased from 63.6% in 2008 to 81.7% in 2017 (3% annual increase, p = .003). CONCLUSION Diabetes related major and toe/ray amputation rates have remained stable but relatively high in Singapore compared with other countries, and the proportion of amputations attributable to diabetes has increased over time. More research is needed to understand the aetiopathological, sociocultural, and health system factors that may underlie the continued high rates of diabetes related amputations in this population.

Abstract
Patients in the rural state of WV are at high-risk for atraumatic amputation. There are opportunities for improved diabetes and vascular disease management in WV. Patients at risk for vascular disease require preventive foot care and medication. Amputation may represent a sentinel event that promotes patient behavior change.
Lower extremity amputation due to peripheral artery disease (PAD) and diabetes (DM) is a life-altering event that identifies disparities in access to healthcare and management of disease. West Virginia (WV), a highly rural state, is an ideal location to study these disparities. The WVU longitudinal health system database was used to identify 1) risk factors for amputation, 2) how disease management affects the risk of amputation, and 3) whether the event of amputation is associated with a change in HbA1c and LDL levels. Adults (≥18 years) with diagnoses of DM and/or PAD between 2011 and 2016 were analyzed. Multivariable logistic regression analyses were performed on patients with lab information for both HbA1c and LDL while adjusting for patient factors to examine associations with amputations. In patients who underwent amputation, we compared laboratory values before and after using Wilcoxon signed rank tests. 50,276 patients were evaluated, 369 (7.3/1000) underwent amputation. On multivariable analyses, Male sex and Self-pay insurance had higher odds for amputation. Compared to patients with DM alone, PAD patients had 12.3 times higher odds of amputation, while patients with DM and PAD had 51.8 times higher odds of amputation compared to DM alone. We found significant associations between odds of amputation and HbA1c (OR 1.31,CI = 1.15–1.48), but not LDL. Following amputation, we identified significant decreases in lab values for HbA1c and LDL. These findings highlight the importance of medical optimization and patient education and suggest that an amputation event may provide an important opportunity for changes in disease management and patient behavior.

Abstract
OBJECTIVE Primary and secondary lower extremity amputation, performed for patients with lower extremity arterial disease, is associated with increased post-operative morbidity. The aim of the study was to assess the impact of regional anaesthesia vs. general anaesthesia on post-operative pulmonary complications. METHODS A retrospective analysis of 45 492 patients undergoing lower extremity amputation between 2005 and 2018 was conducted using data from the American College of Surgeons National Safety Quality Improvement Program database. Multivariable logistic regression was carried out to assess differences in primary outcome of post-operative pulmonary complications (pneumonia or respiratory failure requiring re-intubation) within 48 hours and 30 days after surgery between patients receiving regional (RA) or general anaesthesia (GA). Secondary outcomes included post-operative blood transfusion, septic shock, re-operation, and post-operative death within 30 days. RESULTS Of 45 492 patients, 40 026 (88.0%) received GA and 5 466 (12.0%) RA. Patients who received GA had higher odds of developing pulmonary complications at 48 hours (2.1% vs. 1.4%; adjusted odds ratio [aOR] 1.39, 95% confidence interval [CI] 1.09 - 1.78; p = .007) and within 30 days (6.3% vs. 5.9%; aOR 1.15, 95% CI 1.09 - 1.78; p = .039). The odds of blood transfusions (aOR 1.11, 95% CI 1.02 - 1.21; p = .017), septic shock (aOR 1.29, 95% CI 1.03 - 1.60; p = .025) and re-operation (OR 1.26, 95% CI 1.03 - 1.53; p = .023) were also higher for patients who received GA vs. patients who received RA. No difference in mortality rate was observed between patients who received GA and those who received RA (5.7% vs. 7.1%; odds ratio 0.95, 95% CI 0.84 - 1.07). CONCLUSION A statistically significant reduction in pulmonary complications was observed in patients who received RA for lower extremity amputation compared with GA.

Abstract
AIMS Despite the evidence available on the epidemiology of diabetic foot ulcers and associated complications, it is not clear how specific organizational aspects of health care systems can positively affect their clinical trajectory. We aim to evaluate the impact of organizational aspects of care on lower extremity amputation rates among people with type 2 diabetes affected by foot ulcers. METHODS We conducted a systematic review of the scientific literature published between 1999 and 2019, using the following key terms as search criteria: people with type 2 diabetes, diagnosed with diabetic foot ulcer, treated with specific processes and care pathways, and LEA as primary outcome. Overall results were reported as pooled odds ratios and 95% confidence intervals obtained using fixed and random effects models. RESULTS A total of 57 studies were found eligible, highlighting the following arrangements: dedicated teams, care pathways and protocols, multidisciplinary teams, and combined interventions. Among them, seven studies qualified for a meta-analysis. According to the random effects model, interventions including any of the four arrangements were associated with a 29% reduced risk of any type of lower extremity amputation (OR = 0.71; 95% CI 0.52-0.96). The effect was larger when focusing on major LEAs alone, leading to a 48% risk reduction (OR = 0.52; 95% CI 0.30-0.91). CONCLUSIONS Specific organizational arrangements including multidisciplinary teams and care pathways can prevent half of the amputations in people with diabetes and foot ulcers. Further studies using standardized criteria are needed to investigate the cost-effectiveness to facilitate wider implementation of improved organizational arrangements. Similarly, research should identify specific roadblocks to translating evidence into action. These may be structures and processes at the health system level, e.g. availability of professionals with the right skillset, reimbursement mechanisms, and clear organizational intervention implementation guidelines.

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.

Abstract
OBJECTIVE To evaluate the association between glycemic control (hemoglobin A1C, fasting glucose, and random glucose) and the outcomes of wound healing and lower extremity amputation (LEA) among patients with diabetic foot ulcers (DFUs). RESEARCH DESIGN AND METHODS Medline, EMBASE, Cochrane Library, and Scopus were searched for observational studies published up to March 2019. Five independent reviewers assessed in duplicate the eligibility of each study based on predefined eligibility criteria and two independent reviewers assessed risk of bias. Ameta-analysis was performed to calculate a pooled odds ratio (OR) or hazard ratio (HR) using random effects for glycemic measures in relation to the outcomes of wound healing and LEA. Subgroup analyses were conducted to explore potential source of heterogeneity between studies. The study protocol is registered with PROSPERO (CRD42018096842). RESULTS Of 4572 study records screened, 60 observational studies met the study eligibility criteria of which 47 studies had appropriate data for inclusion in one or more meta-analyses(n = 12,604 DFUs). For cohort studies comparing A1C >7.0 to 7.5% vs. lower A1C levels, the pooled OR for LEA was 2.04 (95% CI, 0.91, 4.57) and for studies comparing A1C ≥ 8% vs. <8%, the pooled OR for LEA was 4.80 (95% CI 2.83, 8.13). For cohort studies comparing fasting glucose ≥126 vs. <126 mg/dl, the pooled OR for LEA was 1.46 (95% CI, 1.02, 2.09). There was no association with A1C category and wound healing (OR or HR). There was high risk of bias with respect to comparability of cohorts as many studies did not adjust for potential confounders in the association between glycemic control and DFU outcomes. CONCLUSIONS Our findings suggest that A1C levels ≥8% and fasting glucose levels ≥126 mg/dl are associated with increased likelihood of LEA in patients with DFUs. A purposively designed prospective study is needed to better understand the mechanisms underlying the association between hyperglycemia and LEA.

Abstract
AIM This study aims to develop and validate a lower extremity amputation (LEA) risk score system in persons with type 2 diabetes. METHODS A retrospective population-based cohort study was conducted among eligible 21,484 participants in the derivation set and 10,742 participants in the validation set who were enrolled in the Taiwan National Diabetes Care Management Program. The risk score system was developed following the steps proposed by the Framingham Heart Study with a Cox proportional hazards model algorithm. Discrimination ability was assessed by the receiver operating characteristic curve, and calibration was performed by Hosmer-Lemeshow test. RESULTS A total of 504 patients developed LEA at an average follow-up of 7.4 years. The point scores were derived from 15 predictors as follows: age, gender, duration of type 2 diabetes, body mass index, HbA1c, triglyceride, eGFR, variation of fasting blood glucose, comorbidities of stroke, diabetes retinopathy, hypoglycemia and foot ulcer, anti-diabetes medication, and use of diuretics and nitrates. The c-statistics for predicting 3-, 5-, and 8-year LEA risks were 0.80 [95% confidence interval (CI) 0.76-0.83], 0.78 (0.75-0.81), and 0.76 (0.74-0.79) in the derivation set, respectively, and 0.81 (0.76-0.85), 0.77 (0.73-0.81), and 0.74 (0.71-0.77) in the validation set, respectively. CONCLUSIONS A new risk score for LEA was developed and validated in the clinical setting with good discriminatory ability. Poor glycemic control, glucose variation, comorbidities, and medication use were identified as predictive factors for LEA in patients with type 2 diabetes.

Abstract
OBJECTIVES Data on vascular patients following amputation in Ireland is lacking, limiting capability to plan services. This paper seeks to benchmark survival and rehabilitation outcomes among vascular patients in Ireland following lower extremity amputation (LEA), and compare subgroups of those undergoing transfemoral (TFA) or transtibial amputation (TTA). METHODS A review was conducted of all patients who underwent non-traumatic TFA or TTA from 2000 to 2009 in a tertiary vascular surgery centre. Demographics, surgical data, perioperative outcomes, medium-term functional outcomes, and survival were assessed. RESULTS One hundred and seventy-two patients (2:1 male: female) underwent 192 non-traumatic LEAs. Median age for TFA was 75 years and TTA 67 (p = 0.002). A percentage of 36.5% had undergone prior attempts at surgical revascularization, 25% had undergone prior distal amputation or debridement. Thirty-three (17%) required stump revision. Twenty-three (13.2%) died in hospital. Median survival for those who died in hospital was 17 days (0-367), versus 17 months (2-106) for those who survived to discharge. CONCLUSION LEA for vascular pathology has significant morbidity and mortality, with long in-patient stays and short median survival; there is need to focus on improving quality of life in postoperative pathways.

Abstract
BACKGROUND Resilience characteristics are a significant factor in the highly variable rehabilitation outcomes for people in middle age or later with transtibial amputation. OBJECTIVE The purpose of this study was to describe resilience characteristics meaningful to people with transtibial amputation in middle age or later, who use a prosthesis. METHODS Semi-structured interviews were conducted, audio recorded, and transcribed with eighteen participants. Interview transcripts were coded and analyzed using a directed content analysis approach, guided by Charney's theory of resilience and Connor-Davidson Resilience Scale scores. RESULTS Five main resilience characteristics (themes) were identified: coping skills, cognitive flexibility, optimism, skill for facing fear, and social support. Participants with higher resilience scores generally described effective use of coping skills, cognitive flexibility, optimism, skills in facing fears, and social support to attain meaningful goals. In contrast, participants with lower resilience scores discussed passive coping strategies, cognitive rigidity, general pessimism, avoidance of activities due to fear, or social support limitations. CONCLUSION Coping skills, cognitive flexibility, optimism, skills for facing fear, and social support were identified as meaningful resilience characteristics for people with transtibial amputation in middle age or later. These characteristics can be targeted and enhanced using resilience interventions. Future research should consider these characteristics when designing and testing rehabilitation focused resilience interventions for people with TTA.

Abstract
AIMS/HYPOTHESIS Elevated glucose level is one of the risk factors for lower extremity amputation (LEA), but whether glycaemic variability confers independent risks of LEA remains to be elucidated. This study aimed to investigate the association between visit-to-visit glycaemic variability and minor and major LEA risks during 8 years of follow-up in type 2 diabetic individuals aged 50 years and older. METHODS This retrospective cohort study included 27,574 ethnic Chinese type 2 diabetic individuals aged ≥50 years from the National Diabetes Care Management Program in Taiwan. Glycaemic variability measures were presented as the CVs of fasting plasma glucose (FPG-CV) and of HbA1c (A1c-CV). The effect of glycaemic variability on the incidence of LEA events was analysed using Cox proportional hazards models. RESULTS After a median follow-up of 8.9 years, 541 incident cases of LEA with a crude incidence density rate of 2.4 per 1000 person-years were observed. After multivariate adjustment, FPG-CV and A1c-CV were found to be significantly associated with minor LEA, with corresponding HRs of 1.53 (95% CI 1.15, 2.04) and 1.34 (95% CI 1.02, 1.77) for the third tertiles of FPG-CV and A1c-CV, respectively. In addition, these associations were stronger amongst older adults with longer diabetes duration (≥3 years) than amongst those with shorter duration (<3 years) (pinteraction < 0.01). CONCLUSIONS/INTERPRETATION Our study suggests that visit-to-visit variations in HbA1c and FPG are important predictors of minor LEA amongst older adults with type 2 diabetes, particularly for those with more than 3 years of diabetes duration.

Abstract
Objective There is limited literature concerning the outcomes and role of THA as a surgical option for amputee patients. The aim of this study is to determine the mid-to long-term survival and complication rates of cementless total hip arthroplasty (THA) in patients with contralateral below knee amputations. Methods A retrospective review of 54 patients with below knee amputation were perfomed who underwent THA for osteoarthritis of the contralateral hip over a 5-year period between 1999 and 2014. Patients were monitored for at least 5 years and assessed with the Harris Hip Score and activities of daily living scale and by evaluating migration or osteolysis around the acetabular cup and femoral stems (amputee group). The amputee group was compared with a control group (non-amputee group) with the same number of patients. Results Differences in the Harris Hip Score (p = 0.021) and activities of daily living scale (p = 0.043) between the two groups were statistically significant lower in the amputee group at 3 months after surgery. However, no differences were found between the groups from 6 months postoperatively to the last follow-up (Harris Hip Score p = 0.812, activities of daily living scale p = 0.885). Radiologically, any cups or stems showed no signs of migration or osteolysis. In the amputee group, dislocation was found in 1 patient 2 months after arthroplasty (p = 0.315) and long stem revision surgery were performed on two patients due to periprosthetic fracture (p = 0.153). Conclusions THA performed on the contralateral side of patients with below knee amputation is considered to be an effective treatment with good clinical and radiological results at mid-to long-term follow-up. Level of evidence Level IV, therapeutic study.

Abstract
BACKGROUND Obesity and inactivity are common and burdensome for people with lower extremity amputation (LEA). The extent to which home-based physical activity/weight management programs are effective and safe for people with LEA is unknown. Translating effective interventions for understudied disability groups is needed. OBJECTIVE To test the feasibility, acceptability, and safety of a weight management and physical activity intervention and obtain preliminary efficacy estimates for changes in weight, body composition, and physical functioning. METHODS Eligibility criteria included: LEA ≥1 year prior, 18-69 years of age, overweight or obese and living in the Seattle area. The intervention arm received self-monitoring tools (e.g., pedometer, scale) and written materials, a single exercise counseling home visit by a physical therapist, and up to 11 telephone calls from a health coach over 20 weeks that involved motivational interviewing to set specific, attainable, and measurable goals. The self-directed control group received the same tools and materials but no home visit or coaching calls. RESULTS Nineteen individuals consented to participate, 15 were randomized (mean age = 56, 73% male, 80% transtibial amputation) and 11 completed 20-week follow-up assessments. The intervention was acceptable and safe. Coached participants had greater decreases in waist circumference (mean difference between groups over 20 weeks, baseline values carried forward: -4.3 cm, 95% CI -8.2, -0.4, p = 0.03) and fat mass (-2.1 kg, 95% CI -3.8, -0.4, p = 0.02). CONCLUSIONS The home-based intervention was promising in terms of efficacy, safety and acceptability. Inclusion of multiple trial centers and increased use of technology may facilitate recruitment and retention.

Abstract
INTRODUCTION Long-term mortality of patients with diabetes who undergo lower extremity amputation (LEA) has not been reported in Spain. METHODS The retrospective cohort included all subjects who underwent LEAs from January 1, 2005 to December 31, 2015 in San Jorge Hospital, Huesca, Spain. Live status of every patient up to September 2017 and the date of death were retrieved using the national death index. RESULTS The series included 203 patients: 116 patients (57.1%) underwent a minor amputation and 87 patients (42.9%) underwent a major amputation. Twenty-five patients (12.3%) died in the perioperative period. Significant risk factors of perioperative mortality were undergoing an above-the-knee amputation, postoperative cardiac complications, age >74 years and acute renal failure. Survival rates at 1, 3, and 5 years were 90.6, 72.8, and 55.5% in patients who underwent a minor amputation compared with 70.8, 41.3, and 34.4% in patients who underwent a major amputation, respectively. Log-rank test between the two groups was χ2 = 12.7 (p < 0.01). CONCLUSIONS Long-term survival was worse in patients who underwent a major amputation with a 5-year mortality of 65.6%. This mortality is worse than what has been reported for some types of common malignancies.

Abstract
Previous research has shown that diabetes mellitus increases the risk of lower extremity amputation in patients with peripheral arterial occlusive disease. However, to our knowledge, no studies have investigated whether systemic autoimmune disease, in particular systemic vasculitis is associated with a higher risk of lower extremity amputation in these patients. To investigate the association between systemic autoimmune disease and lower extremity amputation in patients with severe peripheral arterial occlusive disease based on a secondary analysis of a nationwide, population-based health claims database. Using the inpatient datafile of the Taiwan's National Health Insurance Research Database (NHIRD), we identified 432 patients with severe peripheral arterial occlusive disease that required hospitalization between 2000 and 2012. We also identified patients who had undergone lower extremity amputation and their comorbidities using the same datafile. The risk of lower extremity amputation was assessed using multiple logistic regression analysis, adjusting for age, sex, insured amount, the urbanization level of residence, and the presence of comorbidities. Among patients with severe peripheral arterial occlusive disease, those with systemic vasculitis exhibited a significant higher risk of lower extremity amputation (adjusted odds ratio [aOR] = 6.82, p < 0.001). Diabetes mellitus (aOR = 4.90, p < 0.001) and chronic obstructive pulmonary disease (aOR = 2.87, p = 0.007) were also significantly associated with a higher risk of lower extremity amputation. Among patients with severe peripheral arterial occlusive disease, a significantly higher risk of lower extremity amputation was observed in those with systemic vasculitis.

Abstract
AIM Patients with diabetic end-stage renal disease (ESRD) are at increased risk of lower extremity amputation (LEA) and postoperative complications compared to those without diabetic ESRD. This study sought to determine the factors that influence complications following LEA in patients with diabetic ESRD. METHODS A total of 41 patients with diabetic ESRD (total of 46 amputations) who underwent LEA were enrolled in this study. The electronic medical records were retrospectively reviewed to identify the predictors of postoperative complications. The outcomes were divided into three categories: no complications, minor complications (wounds requiring only local care or oral antibiotics), and major complications (requiring surgical intervention, further amputations, or inducing life-threatening morbidities and mortalities). RESULTS Multivariate logistic regression analysis demonstrated that underlying sepsis (P = 0.007) was the only significant risk factor for major complications, with an odds ratio demonstrating an 8.16 times increased risk of requiring another surgery or mortality compared to those without sepsis. CONCLUSION Preoperative sepsis is an independent risk factor for major complications after LEA in patients with diabetic ESRD. We advise particular caution when performing LEA in diabetic ESRD patients who are also septic. Early amputation, prior to the development of sepsis, is preferable.

Abstract
INTRODUCTION Trauma-related amputations are a common cause of limb loss in the United States. Despite the military and public health impact of trauma-related amputations, distributions of various lower limb amputations and the relative frequency of complications and revision amputations have not been well described. We used the National Trauma Data Bank (NTDB) in order to investigate the epidemiology of trauma-related lower extremity amputations among civilians in U.S. trauma centers. MATERIALS AND METHODS We conducted a secondary data analysis of the 2011-2012 NTDB research data sets, using means and frequencies to characterize the patient population and describe the distribution of major lower extremity amputations. Multivariable regression models were fit to identify predictors of major post-surgical complications, revision amputation, length of hospitalization, and in-hospital mortality. RESULTS A total of 2879 patients underwent a major lower extremity amputation secondary to a trauma-related lower limb injury, representing 0.18% of all NTDB trauma admissions from 2011 to 2012. 80.4% were male and 67.6% were white. The three most frequent definitive amputations preformed included trans-tibial (46%), trans-femoral (37.5%), and through foot (7.6%). The average length of hospitalization for all amputees was 22.7days. Patients with at least one revision amputation stayed in the hospital approximately 5.5days longer than patients not needing a revision amputation. 1204 patients (41.8%) required at least one revision amputation. 27.5% of amputees experienced at least one major post-surgical complication. African Americans experienced a 49% higher major post-surgical complication incidence and stayed, on average, 2.5days longer in the hospital compared to whites. Injury severity score, age, hospital teaching status, presence of a crush injury, fracture location, presence of compartment syndrome, and experiencing a major post-surgical complication were all significant predictors of revision amputation. CONCLUSION We report a high rate of complications and revision amputations among trauma-related lower limb amputees, and identify predictors of surgical outcomes that have not been described in the literature including African American race. Compartment syndrome is a significant predictor of major post-surgical complications, revision amputation, and length of hospitalization.

Abstract
AIM To investigate the total blood loss (TBL) and the safety with respect to the re-amputation rate after transtibial amputation (TTA) conducted with and without a tourniquet.
METHODS The study was a single-centre retrospective cohort study of patients with a primary TTA admitted between January 2013 and April 2015. All patients with a primary TTA were assessed for inclusion if the amputation was performed because of arteriosclerosis or diabetic complications. All patients underwent a standardized TTA procedure that was performed approximately 10 cm below the knee joint and performed with sagittal flaps. The pneumatic tourniquet, when used, was inflated around the femur to a pressure of 100 mmHg above the systolic blood pressure. The number of blood transfusions within the first four postoperative days was recorded. The intraoperative blood loss (OBL), which is defined as the volume of blood lost during surgery, was determined from the suction volume and by the weight difference of the surgical dressings. The trigger for a blood transfusion was set at a decrease in the Hgb level < 9.67 g/dL (6 mmol/L). Transfusions were performed with pooled red blood cells containing 245 mL per portion, which equals 55 g/L of haemoglobin. The TBL during the first four postoperative days was calculated based on the haemoglobin level and the estimated blood volume. The re-amputation rate was evaluated within 30 d.
RESULTS Seventy-four out of 86 consecutive patients who underwent TTA within the two-year study period were included in the analysis. Of these, 38 were operated on using a tourniquet and 36 were operated on without using a tourniquet. There were no significant preoperative differences between the groups. The patients in both groups had a postoperative decrease in their Hgb level compared with preoperative baseline values. The patients operated on using a tourniquet received approximately three millilitres less blood transfusion per kilogram body weight compared with patients operated on without a tourniquet. The duration of surgery was shorter and the OBL was less for the tourniquet group than the non-tourniquet group, whereas no significant difference was observed for the TBL. The TBL median was 859 mL (IQR: 383-1315) in the non-tourniquet group vs 737 mL (IQR: 331-1218) in the tourniquet group (P = 0.754). Within the 30-d follow-up period, 9 patients in the tourniquet group and 11 in the non-tourniquet group underwent a re-amputation at the trans-femoral level. The use of a tourniquet showed no statistically significant association with the 30-d re-amputation at the femur level in the multiple logistic regression model (P = 0.78). The only variable with a significant association with re-amputation was age (OR = 1.07; P = 0.02).
CONCLUSION The results indicate that tourniquets do not cause severe vascular damage with an increased postoperative bleeding or failure rate as the result.

Abstract
AIM To assess whether the surgical apgar score (SAS) is a prognostic tool capable of identifying patients at risk of major complications following lower extremity amputations surgery.
METHODS This was a single-center, retrospective observational cohort study conducted between January 2013 and April 2015. All patients who had either a primary transtibial amputation (TTA) or transfemoral amputation (TFA) conducted at our institution during the study period were assessed for inclusion. All TTA patients underwent a standardized one-stage operative procedure (ad modum Persson amputation) performed approximately 10 cm below the knee joint. All TTA procedures were performed with sagittal flaps. TFA procedures were performed in one stage with amputation approximately 10 cm above the knee joint, performed with anterior/posterior flaps. Trained residents or senior consultants performed the surgical procedures. The SAS is based on intraoperative heart rate, blood pressure and blood loss. Intraoperative parameters of interest were collected by revising electronic health records. The first author of this study calculated the SAS. Data regarding major complications were not revealed to the author until after the calculation of SAS. The SAS results were arranged into four groups (SAS 0-4, SAS 5-6, SAS 7-8 and SAS 9-10). The cohort was then divided into two groups representing low-risk (SAS ≥ 7) and high-risk patients (SAS < 7) using a previously established threshold. The outcome of interest was the occurrence of major complications and death within 30-d of surgery.
RESULTS A logistic regression model with SAS 9-10 as a reference showed a significant linear association between lower SAS and more postoperative complications [all patients: OR = 2.00 (1.33-3.03), P = 0.001]. This effect was pronounced for TFA [OR = 2.61 (1.52-4.47), P < 0.001]. A significant increase was observed for the high-risk group compared to the low-risk group for all patients [OR = 2.80 (1.40-5.61), P = 0.004] and for the TFA sub-group [OR = 3.82 (1.5-9.42), P = 0.004]. The AUC from the models were estimated as follows: All patients = [0.648 (0.562-0.733), P = 0.001], for TFA patients = [0.710 (0.606-0.813), P < 0.001] and for TTA patients = [0.472 (0.383-0.672), P = 0.528]. This indicates moderate discriminatory power of the SAS in predicting postoperative complications among TFA patients.
CONCLUSION SAS provides information regarding the potential development of complications following TFA. The SAS is especially useful when patients are divided into high- and low-risk groups.

Abstract
AIMS Critical appraisal of secondary data made available by the OECD for the time frame 2000-2011. METHODS Comparison of trends and variation of amputations in people with diabetes across OECD countries. Generalized estimating equations to test the statistical significance of the annual change adjusting for major potential confounders. RESULTS A total of 26 OECD countries contributed to the OECD data collection for at least 1 year in the reference time frame, showing a decline in rates of over 40 %, from a mean of 13.2 (median 9.4, range 5.1-28.1) to 7.8 amputations per 100,000 in the general population (9.9, 1.0-18.4). The multivariate model showed an average decrease equal to -0.27 per 100,000 per year (p = 0.015), adjusted by structural characteristics of health systems, showing lower amputation rates for health systems financed by public taxation (-4.55 per 100,000 compared to insurance based, p = 0.002) and non-ICD coding mechanisms (-7.04 per 100,000 compared to ICD-derived, p = 0.001). Twelve-year decrease was stronger among insurance-based financing systems (tax based: -0.16 per 100,000, p = 0.064; insurance based: -0.36 per 100,000; p = 0.046). CONCLUSIONS In OECD countries, amputation rates in diabetes continuously decreased over 12 years. Still, in 2011, one amputation every 7 min could be directly attributed to diabetes. Although interesting, these results should be taken with extreme caution, until common definitions are improved and data quality issues, e.g., a different ability in capturing diabetes diagnoses, are fully resolved.

Abstract
We examined whether brachial‐ankle pulse wave velocity (baPWV) and ankle‐brachial pressure index (ABI) are predictors for mortality in diabetic patients after lower extremity amputation. This was an observational historical cohort study of 102 Japanese diabetic patients after first non‐traumatic lower extremity amputation, with a mean age of 63 years (standard deviation 12 years). The end‐point was all‐cause mortality. During the mean follow‐up period of 3.3 years, 44 patients reached the end‐point. In both univariate and multivariate analyses, baPWV (m/s) (hazard ratio [HR] 1.05 and 1.04, both P < 0.01, respectively), but not ABI (HR 0.38 and 0.89, P = 0.08 and 0.86, respectively), was a significant predictor for the end‐point. When baPWV (above or below the median [21.8 m/s]) and ABI (normal [0.9–1.4] or not) were analyzed as categorical variables, the results were similar. In conclusion, baPWV, but not ABI, might be a predictor for all‐cause mortality in diabetic patients after lower extremity amputation.

Abstract
OBJECTIVE We examined whether HDL cholesterol levels are a predictor for an incidence of lower-extremity amputation (LEA) and wound-related death in patients with diabetic foot ulcers (DFUs). RESEARCH DESIGN AND METHODS This was a single-center, observational, longitudinal historical cohort study of 163 Japanese ambulatory patients with DFUs, 45 woman and 118 men, with a mean (standard deviation) age of 62 (14) years. The primary composite endpoint was defined as the worst of the following outcomes for each individual; (1) minor amputation, defined as amputation below the ankle, (2) major amputation, defined as amputation above the ankle, and (3) wound-related death. RESULTS During the median follow-up period of 5.1 months, 67 patients (41.1%) reached the endpoint (43 minor amputations, 16 major amputations, and 8 wound-related deaths). In the univariate Cox proportional hazard model analysis, lower HDL cholesterol levels (mmol/L) were significantly associated with the incidence of the primary composite endpoint (hazard ratio 0.16 [95% CI 0.08-0.32], p < 0.001). In the multivariate Cox proportional hazard model analysis using a stepwise variable-selecting procedure, HDL cholesterol levels in addition to the presence of ankle brachial index <0.9 or ≥1.4 and serum albumin levels were selected as independent risk factors for the incidence of the endpoint (hazard ratio 0.30 [95% CI 0.14-0.63], p = 0.002). Similar results were obtained when HDL cholesterol levels were treated as a categorical variable (≥1.03 mmol/L or less). CONCLUSIONS HDL cholesterol levels might be a novel clinical predictor for the incidence of LEA and wound-related death in patients with DFUs.

Abstract
AIMS To explore the risk of subsequent ischemic events in type 2 diabetes mellitus (DM) patients who had lower extremity amputations (LEAs) were compared with DM patients without LEAs. METHODS A population-based cohort study was conducted utilizing the data of 2011 patients with newly diagnosed DM with and without LEAs sourced from the Longitudinal Health Insurance Database 2000 (LHID 2000) of the Taiwan National Health Insurance (NHI) program between 1996 and 2008. MAIN OUTCOME MEASURES Relative risks (RRs), hazard ratios (HRs), and disease-free rates for various ischemic events. RESULTS In contrast with the comparison group, subjects with LEAs were more likely to reside in less urbanized areas, be white collar workers, and have higher DM-related costs (p<0.05). Subjects with LEAs also had significantly higher risks of developing ischemic diseases, except intestinal ischemia. In the multivariate Cox proportional hazards regression model analysis, the HR of end-stage renal disease (ESRD) was highest (HR=3.91, 95% CI=2.38-6.42), followed by embolism and thrombosis (HR=3.47, 95% CI=2.12-5.67), other peripheral vascular diseases (HR=3.11, 95% CI=2.11-4.57), atherosclerosis (HR=2.64, 95% CI=1.60-4.35), retinopathy (HR=2.24, 95% CI=1.79-2.80), cerebral ischemia (HR=1.61, 95% CI=1.25-2.06), and coronary artery disease (HR=1.44, 95% CI=1.18-1.74). CONCLUSIONS DM patients with LEAs had significantly higher risks for subsequent ischemic events, particularly among men. The greatest risk detected among DM patients with LEA's was for end-stage renal disease. Disease free survival rates also indicated that the course of generalized DM ischemia proceeded despite treatment.

Abstract
BACKGROUND Obesity is thought to be highly prevalent in persons with lower extremity amputations (LEAs) and can impair physical and social functioning. OBJECTIVE The aim of this study was to determine the prevalence of weight loss intention, weight loss strategies, dietary patterns, and barriers to making dietary changes, and their associations with body mass index (BMI, kg/m(2)), amputation characteristics, health status, and socioeconomic factors. METHODS We conducted a cross-sectional study (n = 150) using data from a self-administered questionnaire. RESULTS 43% of participants were obese and 48% were trying to lose weight; 83% of those trying to lose weight reported trying to "eat differently", but only 7% were following a comprehensive weight loss program involving dietary changes, physical activity, and behavioral counseling. 21% of participants reported ≥ 6 barriers to changing their eating habits (e.g., habit, too little money, stress/depression). Obesity was associated with younger age, lower physical health scores, hypertension, arthritis, and diabetes. Compared to those not trying to lose weight, a greater proportion of those trying to lose weight had a BMI ≥ 35 kg/m(2), age <55 years, higher physical and mental health scores, and more frequent consumption of vegetables, beans, chicken, and fish. CONCLUSIONS Though over half of overweight and obese individuals with LEA were trying to lose weight, few reported following a comprehensive program to lose weight, which may indicate an unmet need for services for this group. To be effective, these programs will need to address the complex physical and mental health challenges that many of these individuals face.

Abstract
Background: Despite low peri-operative mortality after major lower extremity amputation, long-term mortality remains substantial. Metabolic syndrome is increasing in incidence and prevalence at an alarming rate in the USA. Aim: This study was to determine whether metabolic syndrome predicts outcome after major lower extremity amputation. Patients and Methods: A retrospective review of charts between July 2005 and June 2010. Results: Fifty-four patients underwent a total of 60 major lower extremity amputations. Sixty percent underwent below-knee amputation and 40% underwent above-knee amputation. The 30-day mortality was 7% with no difference in level (below-knee amputation, 8%; above-knee amputation, 4%; P = 0.53). The mean follow-up time was 39.7 months. The 5-year survival was 54% in the whole group, and was independent of level of amputation (P = 0.24) or urgency of the procedure (P = 0.51). Survival was significantly decreased by the presence of underlying chronic kidney disease (P = 0.04) but not by other comorbidities (history of myocardial infarction, P = 0.79; metabolic syndrome, P = 0.64; diabetes mellitus, P = 0.56). Conclusion: Metabolic syndrome is not associated with increased risk of adverse outcomes after lower extremity amputation. However, patients with chronic kidney disease constitute a sub-group of patients at higher risk of postoperative long-term mortality and may be a group to target for intervention.

Abstract
Albuminuria has been previously reported as a risk factor for mortality in people with diabetes. In a retrospective series of 455 patients with diabetes and foot ulcers, albuminuria was a predictive factor of in-hospital mortality. Other predictive factors were: white blood cell count>12.9×10(9)/L, haemoglobin<108g/L and age >75 years old.

Abstract
Amputation is a treatment, and not simply part of the natural history of foot disease. However, assessment of amputation incidence is the measure most frequently used to document an outcome reflecting the management of diabetic foot disease, mainly because the data are already captured in most health care systems. Nevertheless, interpretation of the results requires great care. Many centers have recorded decreases in the incidence of amputation in recent years and have concluded that this reflects improvement in clinical care. Although improvement in clinical care is clearly of a priority, it is important not to underestimate the extent to which the at-risk population (those with diabetes) may have changed as a result of changing criteria for the diagnosis of diabetes, as well as the increasing implementation of systematic and opportunistic screening. The incidence of amputation can be calculated and expressed in many ways, with different groups using different criteria for deciding both the numerator and the denominator, and studying populations that may differ in several different ways. Given that the incidence of amputation can also be influenced by a wide variety of clinical and social factors, it is not surprising that considerable variation exists between published studies from different countries. For these reasons it is currently difficult to make meaningful comparisons between data from different countries. On the other hand, the demonstration of wide variation within a single country or between countries or communities that have very similar populations, health care systems, and procedures for documenting amputation incidence is of greater interest. When 8- to 10-fold variation exists within similar health care systems, a risk as large as any published risk factor for amputation, it is essential that the reasons are explored. While race and social deprivation both make an important contribution to variation, another is likely to relate to aspects of the structure of care, including the training and beliefs of individual clinicians, patients’ access to care, preferences of patients, and the ability of a patient to understand the need for care and execute a care plan. This area of study requires further investigation.
