Steatotic liver disease in people with HIV at Tshepong Hospital: A post-mortem analysis.
South Afr J HIV Med
December 2024
Department of Anatomical Pathology, Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, South Africa.
Background: Liver disease is the leading cause of non-AIDS-related mortality in people living with HIV (PLWH). Steatotic liver disease (SLD) is increasingly recognised as an important aetiological factor in liver dysfunction in PLWH.
Objectives: This study aimed to determine the post-mortem prevalence and severity of SLD and determine HIV- and non-HIV-related risk factors associated with it.
Novel biomarkers: the RUNX family as prognostic predictors in colorectal cancer.

While biomarkers have been shown to enhance the prognosis of patients with colorectal cancer (CRC) compared to conventional treatments, there is a pressing need to discover novel biomarkers that can assist in assessing the prognostic impact of immunotherapy and in formulating individualized treatment plans. The RUNX family, consisting of RUNX1, RUNX2, and RUNX3, has been recognized as crucial regulators in developmental processes, with dysregulation of these genes also being implicated in tumorigenesis and cancer progression. In our present study, we demonstrated a crucial regulatory role of RUNX in CD8T and CD103CD8T cell-mediated anti-tumor response within the tumor microenvironment (TME) of human CRC.

MERS is a respiratory disease caused by MERS-CoV. Multiple outbreaks have been reported, and the virus co-circulates with SARS-CoV-2. The long-term (> 6 years) cellular and humoral immune responses to MERS-CoV and their potential cross-reactivity to SARS-CoV-2 and its variants are unknown.

IL-2/IL-2R inhibition improved the prognosis of ischemic stroke by regulating T cells, while the respective contribution of T cells with high/medium/low-affinity IL-2 receptors remained unclear. Single-cell RNA sequencing data of ischemic brain tissue revealed that most of the high-affinity IL-2R would be expressed by CD8 + T cells, especially by a highly-proliferative subset. Interestingly, only the CD8 + T cells with high-affinity IL-2R infiltrated ischemic brain tissues, highly expressing 32 genes (including Cdc20, Cdca3/5, and Asns) and activating 7 signaling pathways (including the interferon-alpha response pathway, a key mediator in the proliferation, migration, and cytotoxicity of CD8 + T cells).

Streptococcus pneumoniae (SPN) is a significant pathogen causing pneumonia and meningitis, particularly in vulnerable populations like children and the elderly. Available pneumonia vaccines have limitations since they only cover particular serotypes and have high production costs. The emergence of antibiotic-resistant SPN strains further underscores the need for a new, cost-effective, broad-spectrum vaccine.
