Comparing probe-based confocal laser endomicroscopy with histology. Are we looking at the same picture?
In conclusion, we found for the first time a positive relationship between a long sleep duration and some markers of melanoma aggressiveness. Future studies are needed to investigate the main pathophysiological mechanisms that could explain this association and the prognostic relevance of this findin
Reproducibility of optical coherence tomography airway imaging
Optical coherence tomography (OCT) is a promising imaging technique to evaluate small airway remodeling. However, the short-term insertion-reinsertion reproducibility of OCT for evaluating the same bronchial pathway has yet to be established. We evaluated 74 OCT data sets from 38 current or former smokers twice within a single imaging session. Although the overall insertion-reinsertion airway wall thickness (WT) measurement coefficient of variation (CV) was moderate at 12%, much of the variability between repeat imaging was attributed to the observer; CV for repeated measurements of the same airway (intra-observer CV) was 9%. Therefore, reproducibility may be improved by introduction of automated analysis approaches suggesting that OCT has potential to be an in-vivo method for evaluating airway remodeling in future longitudinal and intervention studies.
