Outcome of CD20-positive Adult B-cell Acute Lymphoblastic Leukemia and the Impact of Rituximab Therapy.

Background: In adult B cell precursor acute lymphoblastic leukemia (BCP-ALL), CD20 expression has generally been associated with an adverse prognosis. Incorporating rituximab to standard of care is found to improve the outcome of CD20 BCP-ALL. The aim of this study is to estimate the prognostic effect of CD20 expression and the impact of rituximab in BCP-ALL in Saudi Arabia.

Financial Implications and Impact of Pre-existing Atrial Fibrillation on In-Hospital Outcomes in Patients Who Underwent Transcatheter Aortic Valve Implantation (from the National Inpatient Database).

The objective of this study was to evaluate the financial implications and the impact of pre-existing atrial fibrillation (AF) on in-hospital outcomes in patients who underwent transcatheter aortic valve implantation (TAVI) using the Nationwide Inpatient Sample (NIS) database. We identified patients who underwent TAVI from 2011 to 2014. The primary end point was the effect of pre-existing AF on in-hospital mortality.
