Aim: Chronic venous disease (CVD) is very common in nurses. Noticeably, operating room (OR) nurses are predicted to have a major prevalence of varicose veins. We investigated whether the prevalence of CVD in OR nurses was more than non-OR nurses. Methods: Study populations were OR nurses and non-OR nurses at the Faculty of Medicine, Chiang Mai University. Information was compiled by questionnaire. Physical examination was operated by examiners for CVD based on clinical finding using Comprehensive Classification System for Chronic Venous Disorders classification. Results: 222 nurses were included. The prevalence of C0-C2 was notably different between the two groups (P < 0.001). The prevalence of C1 in OR nurses and non-OR nurses was 59.6% and 72.1% while the prevalence of C2 in OR nurses and non-OR nurses was 8.1% and 16.4%, respectively. Nevertheless, the quality of life was not remarkably different between the two groups. Conclusion: The results demonstrated that CVD in non-OR nurses appear to be higher than OR nurses.

Human immunodeficiency virus (HIV) and end-stage renal disease (ESRD) patients contributed to accelerated cardiovascular disease. Comparing the effect on atherosclerosis of the 2 diseases has never been explored. A prospective cohort study enrolled participants who were more than 18 years of age without stroke, coronary, and peripheral arterial disease events. Each HIV-infected person had continuously used antiretroviral therapy and ESRD and required intermittent hemodialysis. We assessed patients using the ankle-brachial index (ABI) and carotid intimal media thickness (CIMT) at enrollment, and 1 year later. The main outcome was the progression of ABI and CIMT per year. Demographic, comorbidities, and serum profiles were collected on entry. A total of 789 HIV-positive and 41 ESRD with HIV-negative patients were recruited. After adjusting for potential confounders at baseline, the ESRD die not significantly decrease ABI by 0.015 in 1 year (P=0 .252). The HIV-infected group had a significantly decreased ABI by 0.020 in 1 year (P < .001), but the reduced rate in the HIV-infected group was not statistically different from those in the ESRD group (P = 0.901). When adjusted for potential confounders, the ESRD had a significant increase of CIMT by 0.111 mm in 1 year (P<0.001). The HIV patients had a significant increase of 0.250 mm CIMT in 1 year (P<0.001). This progression rate was statistically greater in the HIV-infected group versus the ESRD group. HIV infection and ESRD had comparable rates of ABI and CIMT progression in our study. Then, early prevention in asymptomatic atherosclerosis should include not only patients with ESRD but also HIV-infected patients.

Adult patients with human immunodeficiency virus (HIV) appear to be at high risk of cardiovascular disease (CVD). Peripheral arterial disease (PAD) is particularly concerning as it is associated with myocardial infarction and stroke. Nevertheless, the incidence of PAD is still unknown. The authors prospectively recruited HIV-infected patients from the outpatient clinic of the Department of Internal Medicine in our center. We assessed ankle-brachial index (ABI) using the VaSera system™ (Fukuda Denshi Co., Ltd). Patients were grouped into 3 ABI levels: an ABI ≤0.90 was considered abnormal and evidence of PAD, an ABI 1.0 to 1.40 was considered normal, and 0.91 to 0.99 was considered borderline. Cardiovascular risk factors were compared across all 3 levels of ABI and were analyzed using multivariate ordinal logistic regression. Eight hundred ninety-two patients were recruited. The mean age was 42.9 ± 10.0 years and 458 (51.4%) were males. There were 704, 149, and 39 patients in the normal, borderline, and abnormal ABI groups, respectively. The latter group of 39 patients was considered to have PAD, yielding a prevalence of 4.37% (95% confidence interval [CI] 3.21-5.93). Sex ratio, age, education levels, smoking rate, body mass index (BMI), blood pressure, prevalence of comorbidities with hypertension and coronary heart disease, median triglyceride level, reduced kidney function and HIV-1 RNA undetectable ratio, duration of HIV diagnosis, and duration on antiretroviral treatment were significantly different among 3 ABI subgroups. Independent risk factors associated with PAD were being female (odds ratio [OR]: 2.86; 95% CI: 1.94-4.22), being <30 years of age (OR: 4.66; 95% CI: 2.78-7.81), being overweight (BMI 25-25.9; OR: 0.39; 95% CI: 0.20-0.76), being obese (BMI: 30; OR: 3.53; 95% CI: 1.51-8.22), having a diastolic blood pressure ≥80 mmHg (OR: 0.50; 95% CI: 0.35-0.71), and having detectable HIV-1 RNA ≥20 copies/mL (OR: 1.85; 95% CI: 1.13-3.03). In conclusion, the prevalence of PAD in HIV-infected Thais was 4.37% in infected patients on therapy attending outpatient clinics. For this population, PAD appears to be relatively poorly correlated with traditional risk factors of CVD.
