Objectives: Anemia in pregnancy has negative impacts on maternal and neonatal morbidity and mortality and has been described as an issue of health equity. The primary aim of our study was to describe rates of anemia near delivery and assess whether this correlates with neighbourhood-level income status.
Methods: We conducted a retrospective cohort study of pregnant individuals delivering from January 2012 through December 2022 at two large academic centres.
This is a protocol for a Cochrane Review (intervention). The objectives are as follows: The objective of this review is to compare the effectiveness and safety of larger versus smaller RBC volume per transfusion for anemia in hospitalized adults, children, and preterm neonates.

- Cerebral amyloid angiopathy (CAA) is a brain disorder caused by the accumulation of beta-amyloid in small blood vessels, leading to increased risk of bleeding in the brain and associated neurocognitive decline.
- It often appears with age, frequently coexists with Alzheimer's Disease, and can result in significant health issues like spontaneous intracerebral hemorrhage and progressive dementia.
- Recent studies suggest a potential link between blood transfusions and the transmission of CAA, raising concerns about public health and the need for further research on whether CAA can be transmitted through blood, alongside its implications for screening practices.
Introduction: Hospital-based transfusion involves hundreds of daily medical decisions. Medical decision-making under uncertainty is susceptible to cognitive biases which can lead to systematic errors of reasoning and suboptimal patient care. Here we review common cognitive biases that may be relevant for transfusion practice.
