Comparison of the predictive capacity of the Alvarado and AIR scores in the diagnosis of acute appendicitis: A prospective study.

Introduction And Aims: Acute appendicitis stands out as one of the most frequent surgically-treated diseases. Risk scales for acute appendicitis, such as the Alvarado and AIR scoring systems, show good diagnostic yield. The aim of our study was to compare the predictive capacity between the Alvarado and Air scores in the diagnosis of acute appendicitis.

CT-based Bosniak classification of cystic renal lesions: is version 2019 an improvement on version 2005?

Objective: To compare the diagnostic performance and inter-reader agreement of the CT-based v2019 versus v2005 Bosniak classification systems for risk stratification of cystic renal lesions (CRL).

Methods: This retrospective study included adult patients with CRL identified on CT scan between 2005 and 2018. The reference standard was histopathology or a minimum 4-year imaging follow-up.

Tackling the Challenges of FASTQ Referential Compression.

The exponential growth of genomic data has recently motivated the development of compression algorithms to tackle the storage capacity limitations in bioinformatics centers. Referential compressors could theoretically achieve a much higher compression than their non-referential counterparts; however, the latest tools have not been able to harness such potential yet. To reach such goal, an efficient encoding model to represent the differences between the input and the reference is needed.
