Real-World Effectiveness of Nirmatrelvir/Ritonavir on Coronavirus Disease 2019-Associated Hospitalization Prevention: A Population-based Cohort Study in the Province of Quebec, Canada.

Background: Nirmatrelvir/ritonavir has shown to reduce COVID-19 hospitalization and death before Omicron, but updated real-world evidence studies are needed. This study aimed to assess whether nirmatrelvir/ritonavir reduces the risk of COVID-19-associated hospitalization among high-risk outpatients.

Methods: A retrospective cohort study of outpatients with SARS-CoV-2 between March 15 and 15 October 2022, using data from the Quebec clinico-administrative databases.

Simulation-based education to improve management of refractory anaphylaxis in an allergy clinic.

Background: High-fidelity simulations based on real-life clinical scenarios have frequently been used to improve patient care, knowledge and teamwork in the acute care setting. Still, they are seldom included in the allergy-immunology curriculum or continuous medical education. Our main goal was to assess if critical care simulations in allergy improved performance in the clinical setting.

Non-invasive detection of a femoral-to-radial arterial pressure gradient in intensive care patients with vasoactive agents.

Background: In patient requiring vasopressors, the radial artery pressure may underestimate the true central aortic pressure leading to unnecessary interventions. When using a femoral and a radial arterial line, this femoral-to-radial arterial pressure gradient (FR-APG) can be detected. Our main objective was to assess the accuracy of non-invasive blood pressure (NIBP) measures; specifically, measuring the gradient between the NIBP obtained at the brachial artery and the radial artery pressure and calculating the non-invasive brachial-to-radial arterial pressure gradient (NIBR-APG) to detect an FR-APG.

Economic Evaluation of Budesonide Orodispersible Tablets for the Treatment of Eosinophilic Esophagitis: A Cost-Utility Analysis.

Introduction: Budesonide orodispersible tablets (BOT) have been approved in Europe and Canada for the treatment of eosinophilic esophagitis (EoE), a rare and chronic disease. The objective of this study was to assess the economic impact of BOT on both the induction and maintenance of clinico-pathological remission of EoE by performing a cost-utility analysis (CUA).

Methods: For both the induction and maintenance settings, BOT was compared to no treatment in a target population of adult patients with EoE non-responsive to proton pump inhibitor (PPI) treatment.

Economic evaluation of isavuconazole for suspected invasive pulmonary aspergillosis in Canada.

Background: Invasive mold infections (IMI) directly impact life expectancy, especially with delayed therapy. Among IMI, aspergillosis (IA) is more common than mucormycosis (IM), resulting in IA-targeted empirical treatment with voriconazole for suspected invasive pulmonary aspergillosis (IPA), despite IM ineffectiveness. Recently, isavuconazole was approved in Canada for IA and IM.
