Normothermic regional and ex-situ perfusion reduces Postreperfusion syndrome in donation after circulatory death liver transplantation: a retrospective comparative study.

In controlled donation after circulatory death (DCD) liver transplantation, ischemia-reperfusion injury is linked to post-reperfusion syndrome (PRS), acute kidney injury (AKI), and early allograft dysfunction (EAD). Normothermic regional perfusion (NRP) and normothermic machine perfusion (NMP) are techniques that mitigate ischemic injury and associated complications. In this single centre retrospective study, we compared early transplant outcomes of DCD livers undergoing direct procurement (DP) and static cold storage (DCD-DP-SCS), NRP procurement with SCS (DCD-NRP-SCS), or DP with NMP (DCD-DP-NMP).

Characterizing the medical and social complexity experienced by Inuit children and their families from Nunavut who access care at an urban Canadian tertiary level paediatric hospital.

We aimed to characterise the medical and social complexities experienced by Inuit children and their families from Nunavut who were cared for at a general paediatrics clinic at an urban tertiary-level hospital located in Eastern Ontario. A retrospective chart review of this cohort was completed between 2016 and 2019. Two independent reviewers extracted data from charts.

Modulation of cytokeratin and cytokine/chemokine expression following influenza virus infection of differentiated human tonsillar epithelial cells.

Unlabelled: The tonsils have been identified as a site of replication for Epstein-Barr virus, adenovirus, human papillomavirus, and other respiratory viruses. Human tonsil epithelial cells (HTECs) are a heterogeneous group of actively differentiating cells. Here, we investigated the cellular features and susceptibility of differentiated HTECs to specific influenza viruses, including expression of avian-type and mammalian-type sialic acid (SA) receptors, viral replication dynamics, and the associated cytokine secretion profiles.

Mucosal vaccination against SARS-CoV-2 using recombinant influenza viruses delivering self-assembling nanoparticles.

Recombinant influenza viruses are promising vectors that can bolster antibody and resident lymphocyte responses within mucosal sites. This study evaluates recombinant influenza viruses with SARS-CoV-2 RBD genes in eliciting mucosal and systemic responses. Using reverse genetics, we generated replication-competent recombinant influenza viruses carrying heterologous RBD genes in monomeric, trimeric, or ferritin-based nanoparticle forms.

Safety, tolerability, pharmacokinetics, and antimalarial activity of MMV533: a phase 1a first-in-human, randomised, ascending dose and food effect study, and a phase 1b Plasmodium falciparum volunteer infection study.

Background: Novel antimalarials are needed to address emerging resistance to artemisinin and partner drugs. We did two trials to evaluate safety, tolerability, pharmacokinetics, and activity against blood stage Plasmodium falciparum for the drug candidate MMV533.

Methods: A phase 1a first-in-human (FIH) trial was conducted at Nucleus Network (Melbourne, VIC, Australia).
