Abstract
OBJECTIVE Diabetic foot ulcers (DFUs) are a leading cause of morbidity and mortality, which disproportionately impacts underserved populations. This study aimed to provide data regarding the rates and outcomes of amputation in patients admitted with DFU in our health system, which cares for an ethnically diverse and underserved population. METHODS This retrospective study examined the electronic medical records of adult patients hospitalized with DFU at 3 hospitals in our health system between June 1, 2016, and May 31, 2021. RESULTS Among 650 patients admitted with DFU, 88% self-identified as non-White race. Male sex (odds ratio [OR], 0.62), low body mass index (OR, 0.98), and history of smoking (OR, 1.45) were significantly associated with amputation during the study period. A higher erythrocyte sedimentation rate (OR, 1.01), C-reactive protein level (OR, 1.05), and white blood cell count (OR, 1.11) and low albumin level (OR, 0.41) were found to be significantly associated with amputation versus no amputation during admission. The amputation risk during the index admission for DFU was 44%. CONCLUSION Our study identified a high DFU-related amputation risk (44%) among adult patients who were mostly Black and/or Hispanic. The significant risk factors associated with DFU amputation included male sex, low body mass index, smoking, and high levels inflammation or low levels of albumin during admission. Many of these patients required multidisciplinary care and intravenous antibiotic therapy, necessitating a longer length of stay and high readmission rate.

Abstract
INTRODUCTION Type 2 diabetes mellitus (T2DM) is a major public health problem. Foot-related complications are common in diabetic patients. The aim of this study is to identify predictive factors for lower limb amputation (LLA) in order to better identify this at-risk population. METHODS This was a cross-sectional study involving 134 patients who were hospitalised for the management of T2DM complicated by diabetic foot, in the department of endocrinology and diabetology. We included patients with T2DM whose diabetes was diagnosed 10 years ago or more, and who had a diabetic foot problem. Statistical differences between predictors of amputations were tested using: t-tests for numerical variables and chi-square tests for categorical variables. Significant variables were analysed by logistic regression to determine significant predictors. RESULTS The mean duration of diabetes was 17±7 years. We found that 70% of patients with LLA were older than 50 years (p<10-3). The prevalence of LLA was higher (p=0.015) in patients with diabetes for more than 20 years. We noted that 58% of patients who underwent LLA were hypertensive (p<10-3). The majority of patients with LLA (58%) had abnormal micro-albuminuria (p<10-3). We found that 70% (n=12) of patients with LLA had low-density protein cholesterol levels above the target value (p<10-3). Diabetic foot grade ≥4 (4 or 5) according to Wagner's classification, was present in 24% of amputee patients. Based on a 95% confidence interval level, the independent significant predictive factors for LLA in our patients were: T2DM for more than 20 years, hypertension and diabetic foot grade ≥4. CONCLUSIONS After multivariate analysis, the significant independent predictive factors associated with LLA were: T2DM for more than 20 years, hypertension, and diabetic foot grade ≥4. Early management of diabetic foot problems is therefore recommended to avoid amputations.

Abstract
The prevalence of type 2 diabetes mellitus is increasing in both sexes, but men are usually diagnosed at a younger age and lower body fat mass than women. Worldwide, an estimated 17.7 million more men than women have diabetes mellitus. Women appear to bear a greater risk factor burden at the time of their type 2 diabetes diagnosis, especially obesity. Moreover, psychosocial stress might play a more prominent role in diabetes risk in women. Across their lifespan, women experience greater hormone fluctuations and body changes due to reproductive factors than men. Pregnancies can unmask pre-existing metabolic abnormalities, resulting in the diagnosis of gestational diabetes, which appears to be the most prominent risk factor for progression to type 2 diabetes in women. Additionally, menopause increases women's cardiometabolic risk profile. Due to the progressive rise in obesity, there is a global increase in women with pregestational type 2 diabetes, often with inadequate preconceptual care. There are differences between men and women regarding type 2 diabetes and other cardiovascular risk factors with respect to comorbidities, the manifestation of complications and the initiation of and adherence to therapy. Women with type 2 diabetes show greater relative risk of CVD and mortality than men. Moreover, young women with type 2 diabetes are currently less likely than men to receive the treatment and CVD risk reduction recommended by guidelines. Current medical recommendations do not provide information on sex-specific or gender-sensitive prevention strategies and management. Thus, more research on sex differences, including the underlying mechanisms, is necessary to increase the evidence in the future. Nonetheless, intensified efforts to screen for glucose metabolism disorders and other cardiovascular risk factors, as well as the early establishment of prophylactic measures and aggressive risk management strategies, are still required for both men and women at increased risk of type 2 diabetes. In this narrative review we aim to summarise sex-specific clinical features and differences between women and men with type 2 diabetes into risk factors, screening, diagnosis, complications and treatment.

Abstract
To investigate the influencing factors of lower limb amputation in patients with diabetic foot ulcers. Patients with diabetic foot ulcers who were hospitalised in a tertiary general hospital in Guizhou Province from January 2019 to March 2022 were retrospectively collected. Sociological information of the general population, comorbidities, laboratory-related indicators, and information on the specialty situation, using univariate analysis and multifactor analysis, compared the influencing factors of amputation and non-amputee patients. A total of 205 patients with diabetic foot and 69 ampute patients (33.7%) were enrolled. The univariate analysis found that the decrease in HDL cholesterol levels was associated with the occurrence of lower extremity amputation, and logistic stepwise regression analysis showed that HDL-C was inversely correlated with the amputation rate of patients with diabetic foot ulcers, and the risk of amputation at low levels of HDL-C was 2.452 times higher than that of high-level HDL-C (95% CI: 1.105-5.846). Decreased HDL cholesterol levels are an independent predictor of amputation in patients with diabetic foot ulcers.

Abstract
AIMS/HYPOTHESIS This study sought to provide up-to-date pooled global estimates of diabetes-related amputation incidence from 2010 to 2020. METHODS Embase and Medline databases were searched for studies reporting the incidence rate (IR) of diabetes-related amputations from 2010 to 2020. IR estimates of diabetes-related amputations with associated 95% confidence interval (CI) per 100,000 individuals with diabetes were calculated. RESULTS 23 studies were included, reporting 505,390 diabetes-related lower extremity amputations. IR of minor amputations was 139.97 (95% CI 88.18-222.16) per 100,000 individuals with diabetes, among patients with type 1 diabetes was 148.59 (95% CI 65.00-339.68) and in type 2 diabetes was 75.53 (95% CI 29.94-190.54). IR of major amputations was 94.82 (95% CI 56.62-158.80) per 100,000 individuals with diabetes, among patients with type 1 diabetes was 100.76 (95% CI 53.71-189.01) and among type 2 diabetes was 40.58 (95% CI 11.03-149.28). There were 83.84 annual amputations (95% CI 41.67-168.65) per 100,000 women with diabetes and 178.04 (95% CI 81.16-390.55) per 100,000 men. CONCLUSIONS Globally, annual incidence of diabetes-related amputations from 2010 to 2020 has shown to disproportionately affect men and individuals with type 1 diabetes mellitus, although its incidence is not uniform across countries.

Incidence of interventions for diabetic retinopathy and serious lower-limb complications and its related factors in patients with type 2 diabetes using a real-world large claims database. Diabetol Int 2022; 13:548-560. [PMID: 35693997 PMCID: PMC9174399 DOI: 10.1007/s13340-021-00566-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2021] [Accepted: 12/20/2021] [Indexed: 01/16/2023]
Abstract
Aims To examine the incidence of interventions for diabetic retinopathy and serious limb complications and to elucidate the patient attributes related to the incidence of each intervention based on real-world claims data from Japan. Materials and methods A retrospective longitudinal study design involving a 9 year (2009-2018) claims database obtained from the JMDC Inc. Patients with type 2 diabetes aged 20-74 years taking antidiabetic medications were divided into two groups: "patients with newly initiated antidiabetic medication" (Group 1, n = 47,201) and "patients with continuing antidiabetic medication" (Group 2, n = 82,332). The incidence rate for each intervention was analyzed. We also divided Group 1 into the former and latter periods and investigated temporal changes. Results The incidences of the first retinopathy intervention (laser photocoagulation, vitrectomy, or intraocular injection), vitrectomy, and lower-limb amputations in Group 1 were 7.46, 2.37, and 0.31 /1000 person-years, respectively. Those in Group 2 were about 1.2-1.5 times higher. Older age, insulin use, and being dependents rather than insured persons were associated with a higher incidence in both groups after adjustment. While the incidence of the interventions for retinopathy hardly changed during the observation period, that of lower-limb amputations decreased by 40%, with less statistical significance (p = 0.11). Conclusions We showed the incidences of the first retinopathy interventions and lower-limb amputations and their secular trends in patients with diabetes, stratified by whether the antidiabetic medication was newly initiated or not. Older age, insulin use, and being dependents were risk factors of these interventions for diabetic complications.

Abstract
Little is known about the association between deep vein thrombosis (DVT) and arterial complications in patients with type 2 diabetes (T2DM). The aim of this retrospective cohort study was to assess the influence of prior DVT on major adverse limb events (MALEs) and major adverse cardiovascular events (MACEs) in T2DM. A total of 1,628,675 patients with T2DM with or without a history of DVT from 2001 to 2013 were identified in the National Health Insurance Research Database of Taiwan. Before matching, the patients in the DVT group (n = 2020) were older than the control group (66.3 vs. 58.3 years). Patients in the DVT group were more likely to be female than the control group (54.3% vs. 47.5%). Before matching, the DVT group had higher prevalence of most comorbidities, more prescription of antiplatelet, antihypertensive agents and insulins, but less prescription of metformin and sulfonylurea. During a mean follow-up of 5.2 years (standard deviation: 3.9 years), the matched DVT group (n = 2017) have a significantly increased risk of MALE (8.4% vs. 5.2%; subdistribution hazard ratio [SHR] 1.60, 95% CI 1.34–1.90), foot ulcer (5.2% vs. 2.6%, SHR 1.96, 95% CI 1.57–2.45), gangrene (3.4% vs. 2.3%, SHR 1.44, 95% CI 1.10–1.90) and amputation (2.5% vs. 1.7%; SHR 1.42, 95% CI 1.03–1.95) than the 10,085 matched controls without DVT. They also tended to have a greater risk of all-cause mortality (38.1% vs. 33.1%; hazard ratio [HR] 1.18, 95% CI 1.09–1.27) and systemic thromboembolism (4.2% vs. 2.6%; SHR 1.56, 95% CI 1.22–1.99), respectively. We showed the presence of DVT may be associated with an increased risk of MALEs, major amputation, and thromboembolism, contributing to a higher mortality rate in T2DM.

Abstract
The risk of amputation is a sequelae of diabetic foot ulceration, which are significantly increased in diabetic patients and caused huge morbidly and mortality. However, whether the risk amputation in diabetic patients are differing in male and female remains inconclusive. We therefore conducted a systematic review and meta-analysis to assess the sex difference for the risk of amputation in diabetic patients. We systematically searched PubMed, EmBase, and the Cochrane library to identify eligible study from their inception up to November 2020. The diagnostic value of male patients on subsequent amputation risk were assessed by using sensitivity, specificity, positive and negative likelihood ratio (PLR and NLR), diagnostic odds ratio (DOR), and area under the receiver operating characteristic curve (AUC). Twenty-two studies recruited a total of 33,686,171 diabetic patients were selected for quantitative analysis. The risk of amputation in male diabetic patients was greater than female diabetic patients (DOR: 1.38; 95%CI: 1.13–1.70; P<0.001). The sensitivity and specificity for male diabetic patients on the risk of amputation were 0.72 (95%CI: 0.72–0.73), and 0.51 (95%CI: 0.51–0.51), respectively. Moreover, the PLR and NLR of male diabetic patients for predicting amputation were 1.13 (95%CI: 1.05–1.22), and 0.82 (0.72–0.94), respectively. Furthermore, the AUC for male diabetic patients on amputation risk was 0.56 (95%CI: 0.48–0.63). This study found male diabetic patients was associated with an increased risk of amputation than female diabetic patients, and the predictive value of sex difference on amputation risk in diabetic patients was mild.

Abstract
AIM Lower limb amputation (LLA) is a severe consequence of type 2 diabetes mellitus (T2DM), and can affect up to 1% of T2DM patients, leading to an increased risk of premature mortality. Among the factors to predict LLA, it has been highlighted sex, marital status, and previous amputation. However, there is a lack of information about the association between these predictive factors, self-care, and urgency LLA in T2DM patients. PURPOSE To verify the behavior of self-care and to relate it with the predictive factors (sex, marital status, and previous amputation) in urgency LLA T2DM patients. PATIENTS AND METHODS Non-interventional study, with 106 T2DM patients who were in the postoperative period of urgency LLA caused by complications resulting from T2DM. A structured questionnaire was used for sociodemographic and clinical characterization of the sample as well as the Summary of Diabetes Self-Care Activities (SDSCA) tool. It was used the Wilcoxon, Friedman, and Mann-Whitney tests (median, nonparametric populations) to assess the significance of the differences between groups (sex, marital status, and previous amputation), also Spearman correlation coefficient to assess the association between the data (comparison between diagnostic time, sex, previous amputation, ethnicity and systolic arterial hypertension) and a logistic regression analysis considering the item SDSCA related to sex, age and marital status (with partner). RESULTS Significant differences (p<0.05) in the questions "Specific Food" and "Foot care" were found when the participants were grouped by sex. In the relation to marital status, significant differences (p<0.05) were observed for the question "Specific Food". No differences were found between groups with or without previous amputation. CONCLUSION By SDSCA tool, we were able to report that T2DM patients submitted to urgency LLA presented differences in self-care, particularly for sex and marital status.
