Studies evaluating the risk of peripheral arterial disease (PAD) in patients with abdominal aortic aneurysm (AAA) are limited. We used insurance claims data of Taiwan to establish a cohort of 6590 patients with AAA newly diagnosed from 2000 to 2008 and 6590 controls without AAA matched by propensity score. The subsequent incidence density rates of PAD were estimated in both cohorts by the end of 2011, and the AAA cohort to the non-AAA cohort hazard ratios (HRs) of PAD were calculated using Cox proportional hazards models. The incidence density of PAD in the AAA cohort was 3.7-fold greater than that in the non-AAA cohort (14.1 vs 3.66 per 1000 person-years) with an adjusted HR of 3.56 (95% confidence interval [CI] = 2.89-4.39). For those without comorbidities, PAD in the AAA cohort was 7.4-fold greater than that in the non-AAA cohort (12.0 vs 1.61 per 1000 person-years) with an adjusted HR of 6.70 (95% CI = 4.43-10.1). The incidence of PAD in patients with ruptured AAA was lower than that in patients without rupture (6.95 vs 15.0 per 1000 person-years). This study demonstrates that patients with AAA are at increased risk of developing PAD. [ABSTRACT FROM AUTHOR]

Purpose This study evaluated the effect of epilepsy on the development of hyperlipidemia (HL) in Taiwan. Methods We conducted a nationwide population-based cohort study based on data obtained from the National Health Insurance Research Database of Taiwan. We identified 990 cases involving patients whose epilepsy was newly diagnosed between 2000 and 2005, and we also selected a comparison cohort comprising 3960 patients without epilepsy. Cox proportional hazards regression models were used to examine the association between epilepsy and HL. Results The mean follow-up period was 6.63 years for the epilepsy cohort and 7.49 years for the comparison cohort. The incidence rate of HL was 1.28-fold higher in the epilepsy cohort than it was in the comparison cohort (34.14 vs. 26.96 per 1000 person-years), with an adjusted hazard ratio of 1.17 (95% confidence interval, 1.01–1.36) after adjusting the model to account for the effects of sex and comorbidities. The most at-risk patients were those aged 50 to 59 years (hazard ratio, 1.35; 95% confidence interval, 1.04–1.79). For the epilepsy patients, the combined effect of ischemic heart disease, hypertension, and diabetes was associated with a significantly higher risk of developing HL compared with the patients with neither epilepsy nor any comorbidity. Conclusions Middle-aged epilepsy patients are at a significantly higher risk of developing HL. The results could assist in explaining the high risk of cerebral and cardiac vascular disease in epilepsy patients. [ABSTRACT FROM AUTHOR]

Background: Colonic diverticular disease is a chronic gastrointestinal disorder. Previous studies have suggested that chronic gastrointestinal tract is involved in the pathophysiology of Parkinson's disease.Object: This study investigated the potential link between colonic diverticular disease and risk of Parkinson's disease.Methods: Data in this nationwide population-based cohort study were obtained from the National Health Insurance Research Database. Patients with colonic diverticular disease were identified from among 23.22 million insured Taiwanese residents who had been diagnosed between 2000 and 2005 and were aged ≥20 years (n = 23367). The comparison cohort included patients without colonic diverticular disease, matched by sex, age, and all comorbidities with the colonic diverticular disease patients cohort (n = 23367). Using univariable and multivariable Cox proportional hazard regression models, we estimated the adjusted hazard ratio (aHR) for PD with a 95% confidence interval (CI) after adjusting for age, sex, and all of comorbidities.Results: The risk of Parkinson's disease was higher in the CDD cohort than in the comparison cohort (HR = 1.27, 95%CI = 1.10-1.47). Compared with patients aged ≥65 years without CDD, the CDD patients in the equal age group had a 1.25-fold increased risk of PD (95% CI = 1.07-1.46).Conclusion: Colonic diverticular disease may be associated with an increased risk of Parkinson's disease. Thus, the risk of this neurodegenerative disease should be considered in patients with colonic diverticular disease. [ABSTRACT FROM AUTHOR]
