Article Synopsis
- Hemorrhage is a frequent complication of endoscopic retrograde cholangiopancreatography (ERCP), especially after sphincterotomy, but studies on risk factors related to ERCP indications have shown mixed results.
- A systematic review and meta-analysis reviewed 1323 articles, ultimately including 26 studies with over 25,000 patients to assess the link between ERCP indications and hemorrhage risk.
- The results indicated that no specific ERCP indication significantly increased hemorrhage risk, but the authors noted the need for further research due to substantial variability among the studies analyzed.*
Background: The relationship between ABO non-identical transfusion and the outcomes of necrotizing enterocolitis (NEC), and all-cause mortality in very-low birth weight (VLBW) neonates receiving red blood cell transfusion is unknown.
Study Design And Methods: A retrospective multicenter cohort study was conducted in VLBW neonates in neonatal intensive care units between 2004 and 2016. VLBW (≤1500 grams) neonates were followed until discharge or in-hospital death.
Background: Alloimmunisation and haemolytic transfusion reactions (HTRs) can occur in patients with sickle cell disease (SCD) despite providing phenotype-matched red blood cell (RBC) transfusions. Variant RBC antigen gene alleles/polymorphisms can lead to discrepancies in serological phenotyping. We evaluated differences between RBC antigen genotyping and phenotyping methods and retrospectively assessed if partial antigen expression may lead to increased risk of alloimmunisation and HTRs in SCD patients at a tertiary centre in Canada.

This review aims to summarise the evidence on the strength of the association between dietary patterns and the prevalence and incidence of COPD.
Methods: We conducted a comprehensive search of seven databases between 1 January 1980 and 30 November 2019.

Background: Cancer incidence has continuously increased over the past few centuries and represents a major health burden worldwide.
