Objectives: Target trial emulation is an approach that is increasingly used to improve transparency in observational studies and help mitigate biases. For studies declaring that they emulated a target trial, we aimed to evaluate the specification of the target trial, examine its consistency with the observational emulation and assess the risk of bias in the observational analysis.

Design: Methodological systematic review reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

Background And Aims: A recent single-center study reported a significant increase in acute myeloid leukaemia (AML) cases, including mixed-phenotype acute leukaemia (MPAL), after exposure to direct acting agents (DAA). We investigated whether DAA use increased the risk of AML in patients with chronic hepatitis C virus (HCV) infection.

Methods: We conducted a disproportionality analysis of the WHO Pharmacovigilance database Vigibase up to 2020.

Background: After several cases of peculiar hematological malignancies following introduction of new oral anti-hepatitis C virus (HCV) treatments in our recent practice, we aimed to systematically identify all cases of hematological malignancies (HM) in patients with chronic HCV infection and to compare them according to the prescription of oral anti-HCV Direct Acting Antivirals (DAA) treatment or not.

Material/methods: In this single-center retrospective observational study, we included all patients with confirmed HM and chronic HCV infection managed between 2010 and 2019 in the Pitié-Salpêtrière hospital, Paris. Non-inclusion criteria were a benign hematological disorder, an HM preceding chronic HCV infection and HCV acute infection.

Article Synopsis
  • Susac syndrome (SuS) is a rare disease affecting the brain, retina, and inner ear, and the study aimed to see if the amount of brain lesions at the start could predict patient outcomes.* -
  • Conducted in France from 2012 to 2019, the study analyzed 23 patients using MRI to look at the characteristics of brain lesions at diagnosis and during follow-up.* -
  • Results showed that despite differences in the number of brain lesions (low vs. high), there was no significant impact on disability or overall outcomes for patients with SuS.*

Background: Diphtheria is re-emerging in Europe. A total of 36 cases were reported in Europe in 2015 versus 53 cases between 2000 and 2009.
