ReviewWhen less is more: The association between the expression of polymorphic CYPs and AFB1-induced HCC.
An individual's genetic fingerprint is emerging as a pivotal predictor of numerous disease- and treatment-related factors. Single nucleotide polymorphisms (SNPs) in drug-metabolizing enzymes play key roles in an individual's exposure to a malignancy-associated risk, such as Aflatoxin B1 (AFB1)-induced hepatocellular carcinoma (HCC). ⋯ Polymorphic variants of CYP enzymes have a functional impact on the susceptibility to AFB1-induced HCC. Outlining such variation and their implications may provide deeper insights into approaching HCC in a more personalized manner for guiding future risk-assessment, diagnosis, and treatment.

Review Meta AnalysisGlucagon-like peptide-1 receptor agonist semaglutide reduces atrial fibrillation incidence: A systematic review and meta-analysis.
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are new anti-hyperglycaemic drugs with proven cardiovascular (CV) benefit in diabetic and non-diabetic patients at high CV risk. Despite a neutral class effect on arrhythmia risk, data on semaglutide suggest a possible drug-specific benefit in reducing atrial fibrillation (AF) occurrence. ⋯ Semaglutide significantly reduces the occurrence of incident AF by 42% as compared to placebo in individuals at high CV risk, mainly affected by type 2 diabetes mellitus. This effect appears to be consistent independently of the route of administration of the drug (oral or subcutaneous), the presence of underlying diabetes and BMI.

The Fusobacterium genus comprises Gram-negative, obligate anaerobic bacteria that typically reside in the periodontium of the oral cavity, gastrointestinal tract, and female genital tract. The association of Fusobacterial spp. with colorectal tumours is widely accepted, with further evidence that this pathogen may also be implicated in the development of other malignancies. ⋯ These adhesins include Fap2 (fibroblast-activated protein 2), CpbF (CEACAM binding protein of Fusobacteria), FadA (Fusobacterium adhesin A) and FomA (Fusobacterial outer membrane protein A). This review outlines the influence of Fusobacteria in promoting cancer initiation and progression, impacts of therapeutic outcomes and discusses potential therapeutic interventions where appropriate.

Insights into circulating CEACAM1 in insulin clearance and disease progression: Evidence from the Portuguese PREVADIAB2 study.
Type 2 diabetes (T2DM) and obesity are characterized by altered insulin metabolism and action. Reduced hepatic insulin clearance is increasingly recognized as a key contributor to hyperinsulinemia and insulin resistance. CEACAM1 promotes hepatic insulin clearance, and its loss in hepatocytes is associated with reduced insulin clearance in mice and men. This study examines whether CEACAM1 circulating levels reflect compromised insulin metabolism and resistance in the PREVADIAB2 cohort. ⋯ This study demonstrates a progressive increase in insulin resistance and hyperinsulinemia in parallel to elevated BMI and hepatic steatosis prevalence, accompanied by declining circulating CEACAM1 levels. Cluster analysis further linked reduced insulin clearance to lower circulating CEACAM1 levels, suggesting its potential usefulness as a biomarker for metabolic disease progression.

The glycoprotein Carcinoembryonic Antigen-related Cell Adhesion Molecule 1 (CEACAM1), also known as CD66a, is a member of the immunoglobulin superfamily. It is expressed in a variety of tissues including epithelial, immune, as well as endothelial cells, and is crucial to diverse physiological and pathological mechanisms. This review aims to provide a comprehensive understanding of CEACAM1's multifaceted roles in vascular biology and inflammatory processes. ⋯ CEACAM1 is a crucial regulator of vascular homeostasis and inflammation with significant implications for cardiovascular health. Despite the lack of understanding of tissue-specific modulation and isoform-dependent mechanisms, CEACAM1 could be a promising therapeutic target for the prevention of cardiovascular disease in the future.
