Background: The Cardiac Lead Assessment Study (CLAS) was a large prospective, multicenter, international postmarket surveillance study conducted at 45 sites.
Objective: The purpose of CLAS was to examine the prevalence and incidence of externalized conductors and electrical dysfunction in subjects with selected St. Jude Medical defibrillator and left ventricular leads.
Expression of different cytokines and growth factors after myocardial injury has been associated with fibroplasia and dilatation versus reverse remodeling and myocardial repair. Specifically, the proinflammatory/fibrotic mediators: interleukin (IL)-6, epidermal growth factor, and fibroblast growth factor (FGF)-2 cause fibroplasia, whereas reparative cytokines including: IL-1α, IL-1β, IL-4, and IL-13 can limit fibrosis. In appropriate patients, cardiac resynchronization therapy (CRT) reverses cardiomyopathy and improves outcome.

Methods: At CRT-D implant, patients were stratified based on detectable TnT (≥0.01 ng/mL) and elevated BNP (predefined as >440 pg/mL) levels.
Background: Dermatology training programs develop program-specific dermatopathology (DP) curricula. We summarize the current state of DP education in dermatology residency programs and identify opportunities for DP education resource development.
Methods: A 27-question survey was emailed to members of the Association of Professors of Dermatology (APD).
Objectives: To present the results for subgroups defined by center point (CP) measurement and to assess the repeatability of the Fast Retinal Thickness Map analysis results from the Stratus OCT3 machine.
Methods: Two hundred eighty-one replicate OCT3 scans from 134 operators' certification submissions to a reading center were analyzed, including scans from eyes that were reported to be normal and eyes with exudative age-related macular degeneration and with macular edema due to diabetic retinopathy or retinal vascular occlusion.
Results: The mean (SD) of the CP was 284 (150) microm and the center subfield (CC) was 301 (130) microm.
Objective: To develop a simplified clinical scale defining risk categories for development of advanced age-related macular degeneration (AMD).
Methods: Following development of a detailed scale for individual eyes based on gradings of fundus photographs in the Age-Related Eye Disease Study, rates of progression to advanced AMD were assessed in cross-tabulations of presence or absence in each eye of 2 easily identified retinal abnormalities, drusen and pigment abnormalities. Large drusen and any pigment changes were particularly predictive of developing advanced AMD.
Objective: To develop a fundus photographic severity scale for age-related macular degeneration (AMD).
Methods: In the Age-Related Eye Disease Study, stereoscopic color fundus photographs were taken at baseline, at the 2-year follow-up visit, and annually thereafter. Photographs were graded for drusen characteristics (size, type, area), pigmentary abnormalities (increased pigment, depigmentation, geographic atrophy), and presence of abnormalities characteristic of neovascular AMD (retinal pigment epithelial detachment, serous or hemorrhagic sensory retinal detachment, subretinal or sub-retinal pigment epithelial hemorrhage, subretinal fibrous tissue).
Purpose: We conducted a phase I trial of interleukin 2 (IL-2) in combination with chimeric 14.18 (ch14.18) and murine R24 antibodies to determine the maximal tolerated dose (MTD), immunological effects, and toxicity of this treatment combination.
