Analysis of real-world safety, tolerability, and cost efficiency of Sub-Cutaneous administration of Daratumumab in Manitoba.

Introduction: Daratumumab is an anti-CD38 monoclonal antibody used in the treatment of myeloma and other related disorders. To mitigate the risk of infusion related reactions with IV Daratumumab the product monograph suggested a slow administration schedule that extends over several hours. This leads to a significant burden for the outpatients' treatment administration units and indirect costs to the patients such as time toxicity.

Evaluation of infectious complications in patients with myelodysplastic syndromes: a prospective cohort study from the Canadian MDS registry.

Infections are a significant cause of morbidity and mortality in myelodysplastic syndrome (MDS). Precise estimates of infection frequency and severity with modern therapies are uncertain. We conducted a retrospective analysis of a prospective cohort enrolled in a Canadian MDS registry and characterized the frequency and severity of infectious complications.

Supportive care strategies in myelodysplastic syndromes and acute myeloid leukemia in older adults: a national survey of Canadian hematologists.

Myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) are severe myeloid disorders associated with significant morbidity and mortality. Because of patient and disease factors, many older adults are treated as outpatients with less-intensive therapy. Optimal supportive care strategies to minimize bleeding and infectious complications in this patient population have not been systematically evaluated.

Crosstalk with lung fibroblasts shapes the growth and therapeutic response of mesothelioma cells.

Mesothelioma is an aggressive cancer of the mesothelial layer associated with an extensive fibrotic response. The latter is in large part mediated by cancer-associated fibroblasts which mediate tumour progression and poor prognosis. However, understanding of the crosstalk between cancer cells and fibroblasts in this disease is mostly lacking.

Ectopic expression of HNF4α in Het1A cells induces an invasive phenotype.

Barrett's oesophagus (BO) is a pathological condition in which the squamous epithelium of the distal oesophagus is replaced by an intestinal-like columnar epithelium originating from the gastric cardia. Several somatic mutations contribute to the intestinal-like metaplasia. Once these have occurred in a single cell, it will be unable to expand further unless the altered cell can colonise the surrounding squamous epithelium of the oesophagus.

A retrospective observational study examining interhospital transfers from six New Zealand rural hospitals in 2019.

Objective: The aim of this study was to identify the percentage of patients that were transferred from rural hospitals and who received an investigation or intervention at an urban hospital that was not readily available at the rural hospital.

Methods: A retrospective observational study.

Design: Patients were randomly selected and clinical records were reviewed.

Development and internal validation of a clinical prediction model for the diagnosis of immune thrombocytopenia.

Background: Immune thrombocytopenia (ITP) is a diagnosis of exclusion that can resemble other thrombocytopenic disorders.

Objectives: To develop a clinical prediction model (CPM) for the diagnosis of ITP to aid hematogists in investigating patients presenting with undifferentiated thrombocytopenia.

Methods: We designed a CPM for ITP diagnosis at the time of the initial hematology consultation using penalized logistic regression based on data from patients with thrombocytopenia enrolled in the McMaster ITP registry (n = 523) called the Predict-ITP Tool.

White blood cell count trajectory and mortality in septic shock: a historical cohort study.

Purpose: Septic shock is associated with a mortality of 20-40%. The white blood cell count (WBC) at hospital admission correlates with prognosis in septic shock. Here, we explore whether the trajectory of WBC after admission provides further information about outcomes.

Extracellular Vesicles Inhibit the Response of Pancreatic Ductal Adenocarcinoma Cells to Gemcitabine and TRAIL Treatment.

Pancreatic ductal adenocarcinoma remains an aggressive cancer with a low 5-year survival rate. Although gemcitabine has been a standard treatment for advanced pancreatic cancer, patients often develop resistance to this therapeutic. We have previously shown that treating pancreatic cancer cells in vitro with a combination of gemcitabine and the cytokine TRAIL significantly reduced both cell viability and survival.

Long-term follow-up of liver-directed, adeno-associated vector-mediated gene therapy in the canine model of hemophilia A.

Questions remain concerning the long-term efficacy, safety, and site(s) of transgene expression following adeno-associated vector (AAV) therapy. We report a long-term follow-up of 8 (male = 4, hemizygous, and female = 4, homozygous) dogs with severe hemophilia A treated with a single portal vein infusion of a B-domain-deleted (BDD)-canine FVIII (cFVIII) AAV vector (median dose = 1.25 × 1013 vg/kg, AAV2 = 4, AAV6 = 3, and AAV8 = 1).

Transfusion in orthopaedic surgery : a retrospective multicentre cohort study.

Aims: Orthopaedic surgeries are complex, frequently performed procedures associated with significant haemorrhage and perioperative blood transfusion. Given refinements in surgical techniques and changes to transfusion practices, we aim to describe contemporary transfusion practices in orthopaedic surgery in order to inform perioperative planning and blood banking requirements.

Methods: We performed a retrospective cohort study of adult patients who underwent orthopaedic surgery at four Canadian hospitals between 2014 and 2016.

Epidemiology of intravenous immune globulin in septic shock: a retrospective cohort analysis of the Premier Healthcare Database.

Purpose: Intravenous immune globulin (IVIG) may improve survival in people with septic shock. Current utilization patterns of IVIG are unknown. We sought to characterize adult patients with septic shock requiring vasopressors who received IVIG, describes IVIG regimens, and evaluate determinants of IVIG use in patients with septic shock.

Prophylactic tranexamic acid use in non-cardiac surgeries at high risk for transfusion.

Background: Tranexamic acid (TXA) reduces transfusion in a wide range of surgical populations, although its real-world use in non-cardiac surgeries has not been well described. The objective of this study was to describe prophylactic TXA use in non-cardiac surgeries at high risk for transfusion.

Methods: This is a retrospective cohort study of all adult patients undergoing major non-cardiac surgery at ≥5% risk of perioperative transfusion at five Canadian hospitals between January 2014 and December 2016.

Intravenous immune globulin in septic shock: a Canadian national survey of critical care medicine and infectious disease specialist physicians.

Purpose: This national survey evaluated the perceived efficacy and safety of intravenous immune globulin (IVIG) in septic shock, self-reported utilization patterns, barriers to use, the population of interest for further trials and willingness to participate in future research of IVIG in septic shock.

Methods: We conducted a cross-sectional survey of critical care and infectious diseases physicians across Canada. We summarized categorical item responses as counts and proportions.

Variation in prophylactic tranexamic acid administration among anesthesiologists and surgeons in orthopedic surgery: a retrospective cohort study.

Purpose: Tranexamic acid (TXA) reduces red blood cell transfusion in various orthopedic surgeries, yet the degree of practice variation in its use among anesthesiologists and surgeons has not been described. To target future knowledge transfer and implementation strategies, and to better understand determinants of variability in prophylactic TXA use, our primary objective was to evaluate the influence of surgical team members on the variability of prophylactic TXA administration.

Methods: This was a retrospective cohort study of all adult patients undergoing primary total hip arthroplasty (THA), hip fracture surgery, and spine fusion ± vertebrectomy at two Canadian hospitals between January 2014 and December 2016.

A multicenter review of infusion-related reactions to daratumumab for relapsed multiple myeloma in the real world setting.

Background: Daratumumab is used in the treatment of relapsed multiple myeloma. Daratumumab infusion-related reactions can occur with the highest incidence on the first infusion.

Methods: A retrospective review of all daratumumab infusions used as part of the DVd and DRd regimens for relapsed multiple myeloma was undertaken.

Evaluation of Transfusion Practices in Noncardiac Surgeries at High Risk for Red Blood Cell Transfusion: A Retrospective Cohort Study.

Perioperative bleeding is a major indication for red blood cell (RBC) transfusion, yet transfusion data in many major noncardiac surgeries are lacking and do not reflect recent blood conservation efforts. We aim to describe transfusion practices in noncardiac surgeries at high risk for RBC transfusion. We completed a retrospective cohort study to evaluate adult patients undergoing major noncardiac surgery at 5 Canadian hospitals between January 2014 and December 2016.

Efficacy and Safety of Tranexamic Acid in Major Non-Cardiac Surgeries at High Risk for Transfusion: A Systematic Review and Meta-Analysis.

Tranexamic acid (TXA) reduces transfusion requirements in cardiac surgery and total hip and knee arthroplasty, where it has become standard of care. Our objective is to determine the efficacy and safety of TXA in other surgeries associated with a high risk for red blood cell (RBC) transfusion. We identified randomized controlled trials in Medline, Embase, CENTRAL, and CAB abstracts from inception to June 2019.
