Article Synopsis
- - The study investigates the effectiveness of Narrow Band Imaging (NBI) for identifying lesions in ulcerative colitis (UC) using three different classification systems: NICE, Kudo, and the modified Kudo-IBD.
- - Results showed disparities in diagnostic performance, with Kudo-IBD achieving the highest sensitivity (86%) and specificity (79%), indicating its superiority for UC lesion characterization compared to NICE and Kudo classifications.
- - The findings suggest that while NBI's overall diagnostic accuracy for distinguishing between neoplastic and non-neoplastic lesions in UC is generally low, the modified Kudo classification significantly improves this accuracy.
Background & Aims: There is uncertainty regarding the optimal duration of treatment with azathioprine (AZA) in ulcerative colitis (UC) and Crohn's disease (CD). We analyzed the clinical course and predictors of relapse after AZA withdrawal in patients in sustained deep remission.
Methods: A prospective study was performed on patients who stopped their treatment with AZA while being in steroid-free, extended deep remission (normal clinical, endoscopic, and histologic indexes, C-reactive protein, and fecal calprotectin [FC]).

The article compares two of the most followed indices in the monitoring of COVID-19 epidemic cases: the Rt and the RDt indices. The first was disseminated by the Italian National Institute of Health (ISS) and the second, which is more usable due to the lower difficulty of calculation and the availability of data, was adopted by various regional and local institutions.The rationale for the Rt index refers to that for the R0 index, the basic reproduction number, which is used by infectivologists as a measure of contagiousness of a given infectious agent in a completely susceptible population.
