Cardioprotective effects of early versus late initiated antiretroviral treatment in adolescents with perinatal HIV-1 infection.

Whether, and how, cardioprotective effects of antiretroviral treatment (ART) in adolescents with perinatal HIV infection (APHIV) vary with age at treatment initiation is unknown. We used magnetic resonance imaging to compare cardiac status between APHIV initiated on ART at < 5 years of age (early ART, n = 37) and ≥ 5 years of age (delayed ART, n = 34) versus HIV-uninfected peers (n = 21), reporting z-score mean differences adjusted for confounders. Relative to HIV-uninfected adolescents, APHIV with early ART had higher left ventricular (LV) global circumferential strain (GCS) [adjusted mean (95%CI) z-score: 0.

Cardioprotective effects of antiretroviral treatment in adolescents with perinatal HIV infection are heterogeneous depending on age at treatment initiation.

The cardioprotective effects of antiretroviral treatment (ART) in adolescents with perinatal HIV infection (APHIV) may depend on age at ART initiation. We used cardiovascular magnetic resonance (CMR) to characterize and compare residual cardiac changes in apparently healthy APHIV with early and delayed ART initiation compared to sex- and age-similar HIV uninfected peers. We defined early and delayed ART as, respectively, treatment initiated at <5 years and ≥5 years of age.

Clinical and cardiovascular magnetic resonance profile of cardiomyopathy patients from South Africa: Pilot of the IMHOTEP study.

Background: Cardiomyopathy is an important cause of heart failure, however, there is notable lack of data on causes and manifestations of cardiomyopathy in Africa.

Aims: The African Cardiomyopathy and Myocarditis Registry Program (IMHOTEP) aims to address the knowledge gap on etiology, treatment, and outcomes of cardiomyopathy in sub-Saharan Africa.

Methods And Results: We conducted a single-center pilot study to delineate the clinical and cardiovascular magnetic resonance (CMR) phenotypes of cardiomyopathy in South African patients.

Implementation of a Peer-to-Peer Support Program in a Quaternary Pediatric Medical Center.

Healthcare worker burnout is a growing epidemic associated with multiple negative outcomes. Compounding the routine stresses of clinical practice, involvement in adverse events can be emotionally devastating. Healthcare organizations have an obligation to mitigate burnout and promote engagement and resiliency.

Simulating Subject-Specific Aortic Hemodynamic Effects of Valvular Lesions in Rheumatic Heart Disease.

Rheumatic heart disease (RHD) is a neglected tropical disease despite the substantial global health burden. In this study, we aimed to develop a lower cost method of modeling aortic blood flow using subject-specific velocity profiles, aiding our understanding of RHD's consequences on the structure and function of the ascending aorta. Echocardiography and cardiovascular magnetic resonance (CMR) are often used for diagnosis, including valve dysfunction assessments.
