Background: Foot ulcers are costly complication among diabetes patients. These patients have an increased risk of amputation and increased mortality rate. Early recognition of the high-risk foot and sufficient care will save legs and improve patients` quality of life. Figures of incidence of foot ulcers varies and there are only limited information in relation the change of incidence over time. The aim of this study was to estimate 5-year risk for diabetic foot ulcer (DFU), lower extremity amputation (LEA) and all cause of death. Methods: Retrospective cohort study including all subjects with diabetes enrolled in our diabetic outpatient clinic from beginning 2008 until middle 2014. Data were collected from clinical records. Results: 528 subjects with mean age of 61.3 (±13.8), 57.4% were male. The mean of HbA1c in diabetic patients at baseline were 8.1% +/- 1.9%. Cumulative incidence was 1.3% for DFU, 0.18% for LEA and 4.7% for all-cause of death. The prevalence of cardiovascular and cerebrovascular conditions, pneumonia were 2.3%, 1.9%, 2.3%, respectively. Cause of deaths was cancer (64%), pneumonia (20%), cardiovascular death (4%). Conclusions: Several factors may explain the incidence in diabetes-related LEAs. Diabetes prevention strategies and controlling risk factors are important in people with type 1 and 2 diabetes.

Background: We aimed to evaluate the role of genetic polymorphisms in tobacco carcinogen-metabolizing genes and their interactions with smoking in a hospital-based case-control study of Japanese subjects. Materials and Methods: We examine the associations of pancreatic cancer risk with genetic polymorphisms in GSTM1, GSTT1 and GSTP1, phase II enzymes that catalyze the conjugation of toxic and carcinogenic electrophilic molecules. The study population consisted of 360 patients and 400 control subjects, who were recruited from several medical facilities in Japan. Unconditional logistic regression methods were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between genotypes and pancreatic cancer risk. Results: Among the control subjects, the prevalence of the GSTM1-null genotype and the GSTT1-null genotype was approximately 56% and 48%, respectively. Cases and controls were comparable in terms of GSTM1 and GSTT1 genotype distributions. Neither of the deleted polymorphisms in GSTM1 and GSTT1 was associated with the risk of pancreatic cancer, with an age- and sex-adjusted OR of 0.99 (95%CI: 0.74-1.32) for the GSTM1-null genotype, and 0.98 (95%CI: 0.73-1.31) for the GSTT1-null genotype. The OR was 0.97 (95%CI: 0.64-1.47) for individuals with the GSTM1 and GSTT1-null genotypes compared with those with the GSTM1 and GSTT1- present genotypes. No synergistic effects of smoking or GST genotypes were observed. Conclusions: Our results indicate no overall association between the GSTM1 and GSTT1 deletion polymorphisms and pancreatic cancer risk in the Japanese subjects in our study.
