Background: Approximately 10% of people with HIV in Australia had active hepatitis C virus (HCV) infection prior to availability of government-subsidized direct-acting antiviral (DAA) therapy in 2016. This analysis evaluated progress toward HCV elimination among people with HIV in Australia between 2014 and 2023.

Methods: The CEASE cohort study enrolled adults with HIV with past or current HCV infection (anti-HCV antibody positive) from 14 primary and tertiary clinics.

While HIV infection and clonal hematopoiesis (CH) have been linked with inflammatory dysregulation and an increased risk of aging-related comorbidities, their relationship with clinical geriatric syndromes has not been well defined. In the Age-related Clonal Haematopoiesis in an HIV Evaluation Cohort (ARCHIVE) study (NCT04641013), we measure associations between HIV and CH and geriatric syndromes. Of 345 participants (176 with HIV and 169 without HIV), 23% had at least one mutation associated with CH: 27% with HIV and 18% without HIV (p = 0.

This review describes the evolution and enhanced diagnostic capabilities introduced by four-dimensional (4D) flow cardiac magnetic resonance (CMR) in cardiovascular imaging. It charts the historical advancements from echocardiography through to two-dimensional phase-contrast magnetic resonance imaging (2D-PC MRI), culminating in the adoption of 4D flow MRI. This technique affords exhaustive, time-resolved, three-dimensional visualisations of intracardiac and vascular blood flow, refining the accuracy of cardiovascular assessments over traditional methods, especially in complex anatomical settings.
