Ensuring patient informed consent is a key tenet of modern medicine. Although transfusion of blood products is among the most common medical procedures performed in hospitalized patients, there is evidence that informed consent for transfusion is at times incomplete, poorly understood, hurried, and/or inaccurate. This study aimed to develop a narrative that can be used as a framework for practicing physicians and for educational purposes to optimize the process for obtaining informed consent for blood transfusion.

CPT may also potentiate thromboembolic events, given the presence of coagulation factors and the prothrombotic state of COVID-19.
Objectives: The present study aimed to assess and compare the clinical efficacy and the risk of venous thromboembolism (VTE)/arterial thromboembolism (ATE) of CPT in ambulatory versus hospitalized patients with COVID-19.
Background: The demand for rare blood is expected to increase in Canada as its population continues to expand through immigration from diverse regions of the world.
Material And Methods: This paper outlines a national approach to providing rare red cells for patients through the Rare Blood Program of Canadian Blood Services (CBS). Data detailing the rare red cell requests and inventory managed by CBS' Rare Blood Program is provided.
Background: Protein S deficiency is associated with increased risk of venous thromboembolism, complicating the perioperative management of such patients. We present a patient with sickle cell disease (Hb SC genotype) and inherited protein S deficiency who underwent a living-donor renal transplant. To minimize thrombotic risk and sickle cell complications, both plasma exchange and red blood cell (RBC) exchange transfusion were performed pre-operatively.

In this paper, we provide an overview of the current status of medical education in Hematology in Canada including models of training, assessment methods, anticipated challenges, and the effects of the COVID-19 pandemic. We will also discuss additional training that can be pursued after a Hematology residency, with a particular focus On Transfusion Medicine as it was one of the first programs to implement a competency-based curriculum.

We describe a hands-on, anatomy-based workshop that allows learners to practice bone marrow procedures on cadavers. Notably, participants learned how to perform sternal aspirates: a procedure rarely performed in real-life practice.

The frequency of arterial thromboembolism (ATE) in cancer patients is unclear; while evidence examining this question has grown, it has yet to be systematically summarized. This study aims to systematically review the frequency of ATE in patients with cancer.

Methods: Using commercially available assays, by-products of anaerobic metabolism were prospectively measured in the blood and urine of 20 patients with metastatic colorectal cancer (mCRC) and 20 patients with local disease. Twenty-four-hour urine citrate, plasma lactate, ketones, venous blood gas, anion gap, and osmolar gap were investigated.
HPV-positive oropharyngeal carcinoma (OPC) patients have superior outcomes relative to HPV-negative patients, but the underlying mechanisms remain poorly understood. We conducted a proteomic investigation of HPV-positive (n = 27) and HPV-negative (n = 26) formalin-fixed paraffin-embedded OPC biopsies to acquire insights into the biological pathways that correlate with clinical behavior. Among the 2,633 proteins identified, 174 were differentially abundant.

To better understand muscle wasting and anabolic resistance with obesity, we assessed protein 24-h fractional synthesis rates (24-h FSRs) in selected hind-limb muscles of sedentary and resistance-exercised lean and obese Zucker rats. Despite atrophied hind-limb muscles (-28% vs.

Methods: We identified 7 patients with LGMD2B or Miyoshi myopathy (MM) phenotypes and performed detailed history, physical examination, and mutation analyses of genomic DNA.
Results: Ten disease-causing variants of the dysferlin gene (DYSF) were detected, 4 of which were novel and predicted to be pathogenic (IVS33+9G>T, c.
