Introduction: Lower extremity peripheral arterial disease (PAD) affects between 12% and 20% of Americans over the age of 65. PAD compromises quality of life, contributes a high burden of disability and its related health care costs exceed $4 billion/year, yet this preventable CVD outcome remains understudied. Aims: Assess the incidence of hospitalized PAD, and of the most severe form of PAD, critical limb ischemia (CLI), in middle-aged men and women, and evaluate their risk factors in a bi-ethnic, population-based cohort. We hypothesized that incidence of hospitalized PAD and CLI are higher in African Americans, and that modifiable atherosclerosis risk factors in middle age predict these sequelae of PAD. Methods: We analyzed data from 13,865 participants from the Atherosclerosis Risk in Communities Study aged 45–64 without PAD at baseline (1987–89). Incident PAD and CLI events were identified using ICD-9 codes from active surveillance of all hospitalizations among cohort participants from 1987 through 2008. All estimates are incidence rates per 10,000 person-years; nominal statistical significance was achieved for all baseline characteristic comparisons reported. Results: There were 707 incident hospitalized PAD during a median of 18 years of follow-up (249,570 person-years). The overall age-adjusted incidence of PAD and limb-threatening CLI were 26.0 and 9.6 per 10,000 person-years, respectively. Incidence of hospitalized PAD was higher in African Americans than whites (34.7 vs. 23.2) and in men compared to women (32.4 vs. 26.7). Baseline characteristics associated with age-adjusted incident PAD (per 10,000 person-years) compared to their referent groups were diabetes (91.2 vs. 19.0), history of smoking (33.6 vs. 16.2), hypertension (42.6 vs. 18.6), coronary heart disease (81.4 vs. 24.1), and obesity (41.5 vs. 20.2). Incidence of CLI also was higher among African Americans (21.0 vs. 5.9) and in men (10.5 vs. 8.9 per 10,000 person-years). Baseline characteristics associated with incident CLI were similar to those for PAD. Conclusions: The absolute risk of hospitalized lower extremity PAD in this community-based cohort is of a magnitude similar to that of heart failure and of stroke. As modifiable factors are strongly predictive of the long-term risk of hospitalized PAD and CLI, particularly among African Americans, our results highlight the need for effective risk factor prevention and control.

Introduction: Diabetic foot syndrome (DFS) is the major cause of hospitalization for diabetes-related complications. Protective sensation loss and impaired vision increase the susceptibility for minor feet trauma, which results in diabetic foot ulceration with or without subsequent infection. Peripheral arterial disease is a major cause of impaired ulcer, wound healing and gangrenous diabetic foot. The most important intervention to prevent diabetic foot ulceration and its consequences is early recognition of high-risk patients and their risk factors and referral to appropriate medical departments. There are various risk factors for major lower extremity amputations related to diabetic foot, which includes microvascular diseases, infections, long duration of diabetes, poor glycemic control, peripheral arterial disease, old age and associated cardiovascular comorbidities. Material and Methods: This study was done on the review of medical records of consecutive type 2 diabetic patients. Admitted patients were treated and managed according to the standard protocol of the hospital. History, clinical and physical examination were carried out on each patient. Ulcer characteristics like infection and depth of the ulcer, site of ulcer were assessed. Associated diabetic neuropathy and peripheral arterial disease was assessed by a clinical method. Age, sex, body mass index (BMI), smoking, duration of diabetes, diabetic control therapy, associated hypertension, cardiac diseases were recorded. The glycated haemoglobin level (HbA1c) were recorded. Results: A total of 128 patients with diabetic foot were included in the study of which 76(59.4%) were male and 52(40.6%) were female. Of the 76 male 6 (4.7%) had major amputation and out of 52 female 4(3.1%) had major amputation, thus total number of major amputations were 10(7.8%). Statistically significant difference was observed in HbA1C and duration of diabetes group in amputation. High HbA1C and more duration of diabetes was associated with the higher number of amputation. The rate of amputation was much higher among patients hypertension, smoking, cardiac diseases and stroke. Conclusion: Poor glycemic controls and duration of diabetes are the important independent risk factors for diabetes-related major lower extremity amputations. Keywords: DFS, BMI, smkoing, DM

Non-traumatic upper extremity amputations are an increasing concern with the rising prevalence of diabetes mellitus. To ascertain the risk factors and mortality rates for these amputations, the demographic information, amputation history, comorbidities and clinical outcomes of 140 patients who underwent non-traumatic upper extremity amputations between 1 January 2004 and 31 October 2017 were studied. Correlations were assessed using Cochran-Armitage chi-squared tests, odds ratios and multivariate binomial logistic regression as appropriate. Diabetes mellitus, coronary artery disease, end-stage renal failure, peripheral arterial disease and prior lower extremity amputation were significant risk factors for multiple upper extremity amputations. One-year, 2-year and 5-year mortality rates were 12%, 15% and 38%, respectively, following first upper extremity amputation. The risk factors for upper extremity amputations correspond with those for lower extremity amputations, comprising mainly diabetes mellitus and its related comorbidities. The mortality rates for non-traumatic upper extremity amputations highlight their significant burden on patients. Level of evidence: III
