Article Abstract
Objectives: To evaluate the occurrence of ventricular systolic dysfunction in human immunodeficiency virus (HIV)-related pulmonary arterial hypertension (PAH).
Background: Patients with HIV-related PAH may develop ventricular systolic dysfunction both as a consequence of PAH progression or of the myocardial involvement from the HIV infection itself.
Methods: Cardiac magnetic resonance imaging was applied to measure ejection fraction for the left ventricle and the right ventricle in patients with HIV-related PAH (n = 27) and in patients with PAH from other aetiologies (n = 115).
Results: In HIV-related PAH, ejection fraction values were lower and a higher proportion of patients presented with an advanced stage of ventricular dysfunction (55% vs. 25%; p = 0.009). In a multivariate model, PAH related to HIV infection remained independently associated with advanced ventricular dysfunction (p = 0.011).
Conclusions: Patients with HIV-related PAH have more prevalent and severe ventricular systolic dysfunction compared to patients with PAH from other aetiologies.

Quantifying Structural Disadvantage in HIV Prevention: Development and Validation of the HIV-Specific Social and Structural Determinants Index in the United States.

Structural inequities significantly shape disparities across the HIV care continuum, yet few validated tools exist to quantify HIV-specific structural vulnerability at the population level in the United States. This study introduces and validates the HIV-Specific Social and Structural Determinants of Health Index (HIV-SSDI), a multi-dimensional, state-level index designed to capture structural disadvantage relevant to HIV prevention and care. Using publicly available state-level index (2008-2023) spanning nine structural domains, we developed the HIV-SSDI through exploratory factor analysis with three extraction methods: principal component analysis, maximum likelihood, and minimum residual.

Purpose: To characterize causes of death in patients with bone metastases and to support data-driven approaches to survivorship planning and clinical decision-making in this population.
Methods: Using data from the SEER registry (2010-2021), we identified 186,404 patients with newly diagnosed bone metastases. Causes of death were classified as related to the cancer-specific, non-cancer, or subsequent cancer.

Background: HIV-related stigma among healthcare providers remains a significant barrier to effective HIV care and treatment. This study aimed to assess HIV-related stigma and associated factors among healthcare providers in primary healthcare clinics (PHCs) in Almaty, Kazakhstan.
Methods: A mixed-methods design was employed, involving quantitative surveys and qualitative in-depth interviews.
Influence of self-compassion on HIV-related stigma, health-related quality of life, and depression among HIV/AIDS patients.

: People living with HIV/AIDS (PLWHA) may experience HIV-related stigma, which could negatively impact health-related quality of life (HRQoL) and increase symptoms of depression. Self-compassion is a positive personality attribute that may protect PLWHA against stigmatisation. Previous studies have not examined the influence of self-compassion on the association between HIV-related stigma, HRQoL, and depression.

AIDS-related mortality has significantly decreased due to antiretroviral therapy (ART), leading to a substantial increase in average lifespan. Consequently, cardiovascular diseases have become a growing concern among people living with HIV (PLWH). This study aimed to assess the cardiovascular risk profile of people living with HIV receiving ART and to explore the association between traditional and HIV-related factors with increased cardiovascular risk.
