Classical Hodgkin Lymphoma (CHL) is characterized by a complex tumor microenvironment (TME) that supports disease progression. While immune cell recruitment by Hodgkin and Reed-Sternberg (HRS) cells is well-documented, the role of non-malignant B cells in relapse remains unclear. Using single-cell RNA sequencing (scRNA-seq) on paired diagnostic and relapsed CHL samples, we identified distinct shifts in B-cell populations, particularly an enrichment of naïve B cells and a reduction of memory B cells in early-relapse compared to late-relapse and newly diagnosed CHL.

MicroRNAs (miRNAs) are critical regulators of gene expression in cancer biology, yet their spatial dynamics within tumor microenvironments (TMEs) remain underexplored due to technical limitations in current spatial transcriptomics (ST) technologies. To address this gap, we present STmiR, a novel XGBoost-based framework for spatially resolved miRNA activity prediction. STmiR integrates bulk RNA-seq data (TCGA and CCLE) with spatial transcriptomics profiles to model nonlinear miRNA-mRNA interactions, achieving high predictive accuracy (Spearman's ρ > 0.

Background: Despite advances in HIV care, viral load suppression (VLS) among adolescents living with HIV (ALHIV) in Uganda continue to lag behind that of adults, even with the introduction of dolutegravir (DTG)-based regimens, the Youth and Adolescent Peer Supporter (YAPS) model, and community-based approaches. Understanding factors associated with HIV viral load non-suppression in this population is critical to inform HIV treatment policy. This study assessed the prevalence and predictors of viral load non-suppression among ALHIV aged 10-19 years on DTG-based ART in Soroti City, Uganda.

This analysis evaluates the longitudinal impact of extracorporeal membrane oxygenation (ECMO) and ventricular assist device (VAD) on the progression of motor delay and cognitive delay in pediatric heart transplant recipients. The United Network for Organ Sharing Registry was queried for pediatric patients (<18 years) who received a heart transplant between 2008 and 2022 and were bridged-to-transplantation with either ECMO or VAD. Patients were further stratified based on the progression of delay status pretransplant to post-transplant.

Background: IgA nephropathy is a disease with a highly variable natural history, for which there is an increasing understanding of the role of complement activation in its pathogenesis and progression. We aimed to assess the clinical and prognostic implications of C4d staining in the kidney biopsy of IgA nephropathy patients.
Methods: This was a retrospective observational study wherein the medical records of IgA nephropathy patients were reviewed and baseline characteristics, kidney biopsy findings, treatment response and follow-up data were noted.
