Objective: To report clinical outcomes of skeletally immature dogs with antebrachial deformities secondary to premature closure of the distal radial physis (PCDRP) treated with angular corrections and distraction osteogenesis using circular external skeletal fixation (CESF).

Study Design: Retrospective multi-institutional case series.

Animals: A total of 12 client-owned dogs with premature distal radial physeal closure.

Introduction: Fluid thickeners used in the management of oropharyngeal dysphagia exhibit non-Newtonian shear-thinning rheology, impacting their viscosity during deglutition. This study investigated how the rheological properties of thickened fluids affect pharyngeal swallowing parameters in patients with oropharyngeal motor disorders diagnosed by pharyngeal high-resolution manometry impedance (P-HRM-I).

Methods: Seventy-two patients (18-89 years) referred for P-HRM-I were diagnostically assessed with a 10 mL thin bolus.

Background And Hypothesis: Efficient arteriovenous access (VA) surveillance is vital for early identification of dysfunctional access, allowing timely intervention to prevent thrombosis. This study compares the efficacy of adding remote software surveillance to standard clinical care across our units.

Methods: We conducted a 12-month prospective study on maintenance hemodialysis (HD) patients using Vasc-Alert software technology to assist clinical decision-making in 2 satellite HD units (Group 1) and standard care in the remaining 3 HD units (Group 2) .

Background: With improved outcomes in human immunodeficiency virus (HIV) due to the use of anti-retroviral therapy, ensuring adequate preventative healthcare and management of HIV-related comorbidities is essential.

Aims: To evaluate adherence with recommended guidelines for comorbidity and immunisation status screening amongst people living with HIV within a hospital-based setting across two timepoints.

Methods: A single-centre retrospective case series was conducted at a hospital between 2011 and 2021.

Background: Malaria remains a substantial public health burden among young children in sub-Saharan Africa and a highly efficacious vaccine eliciting a durable immune response would be a useful tool for controlling malaria. R21 is a malaria vaccine comprising nanoparticles, formed from a circumsporozoite protein and hepatitis B surface antigen (HBsAg) fusion protein, without any unfused HBsAg, and is administered with the saponin-based Matrix-M adjuvant. This study aimed to assess the safety and immunogenicity of the malaria vaccine candidate, R21, administered with or without adjuvant Matrix-M in adults naïve to malaria infection and in healthy adults from malaria endemic areas.
