RESUMO
OBJECTIVE: The aim was to identify the prevalence of inadequate health literacy in patients with arterial vascular disease. This was a cross sectional study. METHODS: Patients with arterial vascular disease visiting the outpatient clinic between January 5, 2015 and December 28, 2016, were randomly included and screened for inadequate health literacy with the Newest Vital Sign-Dutch (NVS-D), a validated health literacy assessment measure. A score of <4 out of six identified individuals with inadequate health literacy. Age, gender, highest education level, and reason for consultation were also registered. Data analysis was performed using Student's t-test or the Mann-Whitney U test and chi-square test. Logistic regression with backward elimination was applied to identify independent predictors. RESULTS: A total of 202 patients were included. The mean NVS-D score was 1.91 (SD ± 1.948, median 1). The prevalence of inadequate health literacy was 76.7%. A significantly higher prevalence of inadequate health literacy was found in patients ≥65 years (p < .001) and patients with a lower education level (p < .001). No significant difference was found between female/male patients (p = .056), nor between participants with peripheral arterial occlusive disease and abdominal aortic aneurysm (p = .116). Age (OR 1.060; 95% CI 1.017-1.104; p = .005) and education level (OR 0.164; 95% CI 0.078-0.346; p < .001) were identified as independent predictors of inadequate health literacy. CONCLUSION: This study shows a prevalence of inadequate health literacy of 76.7% in patients with arterial vascular disease, with a significantly higher prevalence in patients ≥ 65 years and patients with a lower education level. The high prevalence of inadequate health literacy should be considered when information is provided, and suggests the need to further investigate the best methods to convey medical information to this group of vulnerable patients.

OBJECTIVE: To evaluate the feasibility and anatomical success of endovenous laser ablation (EVLA) of incompetent perforating veins (IPV). METHODS: All 135 consecutive patients with IPV treated with ELVA (intention-to-treat) from January 2008 to December 2013 were included. Up to the end of 2011, an 810-nm laserset (14 W) was used, and afterwards, a 1470-nm laserset (6 W) was introduced. Duplex ultrasound was performed at 6 weeks' follow-up to assess anatomical success. RESULTS: Overall anatomical success at 6 weeks' follow-up was 56%. Anatomical success was 63% after treatment with 810 nm and 45% with 1470 nm (p = 0.035). This difference in the success rate seems associated with the significantly higher amount of energy delivered in the 810 nm cohort (560 J) versus 1470 nm (186 J). Regardless of the type of laser, anatomical success was significantly higher after treatment with more than 400 J (66%) compared with 0-200 J (40%, p = 0.009) and 200-400 J (43%, p = 0.029). Complications were limited to two cases of transient paresthesia. CONCLUSIONS: EVLA of IPVs is safe and feasible. The amount of energy is highly important in achieving anatomical success.

The aim of this study was to describe specific histological findings of the Coxiella burnetii-infected aneurysmal abdominal aortic wall. Tissue samples of the aneurysmal abdominal aortic wall from seven patients with chronic Q fever and 15 patients without evidence of Q fever infection were analysed and compared. Chronic Q fever was diagnosed using serology and tissue PCR analysis. Histological sections were stained using haematoxylin and eosin staining, Elastica van Gieson staining and immunohistochemical staining for macrophages (CD68), T lymphocytes (CD3), T lymphocyte subsets (CD4 and CD8) and B lymphocytes (CD20). Samples were scored by one pathologist, blinded for Q fever status, using a standard score form. Seven tissue samples from patients with chronic Q fever and 15 tissue samples from patients without Q fever were collected. Four of seven chronic Q fever samples showed a necrotizing granulomatous response of the vascular wall, which was characterized by necrotic core of the arteriosclerotic plaque (P = 0.005) and a presence of high numbers of macrophages in the adventitia (P = 0.007) distributed in typical palisading formation (P = 0.005) and surrounded by the presence of high numbers of T lymphocytes located diffusely in media and adventitia. Necrotizing granulomas are a histological finding in the C. burnetii-infected aneurysmal abdominal aortic wall. Chronic Q fever should be included in the list of infectious diseases with necrotizing granulomatous response, such as tuberculosis, cat scratch disease and syphilis.
