Article Abstract
Immunohistochemical studies have identified complement component C1q in MS lesions. We aimed to compare serum (sC1q) and CSF (csfC1q) levels in a large cohort of MS patients (pwMS) (n = 222) with those of healthy controls (HC, n = 52), individuals with other immune (IND, n = 14), and non-immune neurological disorders (nIND, n = 15), and to analyze their correlation with other biomarkers. pwMS were divided into three series based on their origin. CSF samples were unavailable for HC. All three pwMS cohorts had lower sC1q levels compared to HC and IND. csfC1q was higher in one pwMS cohort, with a trend in another, and correlated with IgG, Free Kappa Light Chains, GFAP, and Chitinase-3 Like Protein-1 in CSF. Our findings suggest a significant role for C1q in MS pathophysiology, potentially serving as a biomarker for disease identification.

Can Sex-based Variations in the Immune Responses to AAV Gene Therapy Affect Safety and Efficacy? A Review of Current Understanding.

Gene Transfer and Immunogenicity Branch, Division of Gene Therapy 2, Office of Gene Therapy, Office of Therapeutic Products, Center for Biologics Evaluation and Research, US Food and Drug Administration, WO52 RM3124, 10903 New Hampshire Ave, Silver Spring, Maryland, 20993-0002, USA.
As the field of gene therapy advances and as the importance of sex as a biological variable in shaping viral immune responses is recognized, the impact of sex on adeno-associated virus (AAV) vectors mediated gene therapies remain largely unexplored. Here we review current understanding of the immune response against AAV gene therapy as well as the knowledge of sex differences observed in viral responses. We discuss sex differences in innate immune mechanisms such as Toll-like receptor recognition and complement activation, as well as the functional responses of key immune cells such as dendritic cells, macrophages, and T/B cells that are involved in AAV immunogenicity.

Background: The integration of digital tools in aesthetic medicine has enhanced the precision of facial feature analysis. Using concepts like the Golden Ratio, these technologies enable more objective assessments of facial proportions and symmetry. The beauty scanner-face analyzer (BS-FA) app offers a digital approach to evaluate geometric proportions and facial alignment, providing valuable data for preoperative planning in plastic surgery and aesthetic treatments.

Retention on antiretroviral therapy (ART) is critical for achieving viral load suppression (VLS) among people living with HIV (PLHIV). Retention remains challenging in high-prevalence settings like Malawi. Short messaging service (SMS) interventions, particularly hybrid two-way texting (2wT), show promise in improving ART retention.

Background: Substantial advances have been made in therapeutics for IgA nephropathy. We conducted a systematic review and meta-analysis to evaluate the comparative efficacy and safety of existing and novel IgA nephropathy therapies.
Methods: We searched MEDLINE and Embase databases from inception to May 21, 2025 for Phase 2b and 3 multi-center, randomized, placebo-controlled trials enrolling patients with IgA nephropathy that reported treatment effects on proteinuria and/or estimated glomerular filtration rate (eGFR) slope.
Noninvasive Anatomical and Functional Imaging for Hemodynamic Relevance in Right Coronary Artery Anomalies.

Department of Cardiology, Inselspital University Hospital of Bern, University of Bern, Bern, Switzerland.
Importance: Right anomalous aortic origin of a coronary artery (R-AAOCA) is a rare congenital condition increasingly diagnosed with the growing use of cardiac imaging. Due to dynamic compression of the anomalous vessel, invasive fractional flow reserve (FFR) during a dobutamine-atropine volume challenge (FFR-dobutamine) is considered the reference standard. A reliable alternative method is needed to reduce extensive invasive testing, but it remains uncertain whether noninvasive imaging can accurately assess the hemodynamic relevance of R-AAOCA.
