Consensus standards for acquisition, measurement, and reporting of intravascular optical coherence tomography studies

Objectives: The purpose of this document is to make the output of the International Working Group for Intravascular Optical Coherence Tomography (IWG-IVOCT) Standardization and Validation available to medical and scientific communities, through a peer-reviewed publication, in the interest of improving the diagnosis and treatment of patients with atherosclerosis, including coronary artery disease. Background: Intravascular optical coherence tomography (IVOCT) is a catheter-based modality that acquires images at a resolution of ∼10 μm, enabling visualization of blood vessel wall microstructure in vivo at an unprecedented level of detail. IVOCT devices are now commercially available worldwide, there is an active user base, and the interest in using this technology is growing. Incorporation of IVOCT in research and daily clinical practice can be facilitated by the development of uniform terminology and consensus-based standards on use of the technology, interpretation of the images, and reporting of IVOCT results. Methods: The IWG-IVOCT, comprising more than 260 academic and industry members from Asia, Europe, and the United States, formed in 2008 and convened on the topic of IVOCT standardization through a series of 9 national and international meetings. Results: Knowledge and recommendations from this group on key areas within the IVOCT field were assembled to generate this consensus document, authored by the Writing Committee, composed of academicians who have participated in meetings and/or writing of the text. Conclusions: This document may be broadly used as a standard reference regarding the current state of the IVOCT imaging modality, intended for researchers and clinicians who use IVOCT and analyze IVOCT data

Determinants of Erectile Dysfunction Risk in a Large Series of Italian Men Attending Andrology Clinics

Objective: To assess determinants of ED in men who asked for a free of charge andrologic consultation during a week focused on andrologic prevention in Italy. Methods: Men were invited to attend 178 participating andrology centers for a free of charge visit for counselling about urologic or andrologic conditions. Data were recorded with a simple questionnaire used by all centers. Results: 2499 (19.9%) were diagnosed having ED. The frequency of ED increased with age, ranging from 4.6% in men under 25 years, to 37.6% in men over 74. In comparison with men with primary education the OR of ED was 0.8 (95% CI 0.7-0.9) in men with secondary education and 0.7 (95% CI 0.6-0.9) in those with university degree. After adjusting for age, the risk of ED was significantly higher in men consuming more than 3 glasses/day of alcoholic drinking (OR 1.4, 95% CI 1.1-2.0), in subjects smoking more than 10 cigarettes/day (OR 1.2, CI 95% 1.1-1.4) and in former smokers (OR 1.2, CI 95% 1.1-1.4). Men performing at least two hours per week of physical activity had a decreased risk of ED (OR 0.8, CI 95% 0.7-0.9). We found an increased risk of ED in men with diabetes (OR 1.2, 95% CI 1.1-1.4), hypertension (OR 1.3, 95% CI 1.1-1.4), cardiopathy (OR 1.5, 95% CI 1.3-1.8) and hypercholesterolemia (OR 1.4, 95% CI 1.2-1.6). Conclusions: This study provides further data on determinants of ED risk in a large data set and underlines the relationship between ED and cardiovascular diseases. \ua9 2003 Elsevier B.V.
