Retinal artery occlusion (RAO) is a critical ophthalmic emergency with a high risk of significant visual impairment. While traditional treatment aims to promptly restore blood flow to the retina, recent research has investigated the potential benefits of anticoagulation therapy for managing this condition. This paper reviews current literature and clinical trials investigating the efficacy and safety of anticoagulant and antiplatelet therapies, such as systemic heparinization and direct oral anticoagulants and aspirin, in treating RAO.

Genomic and cellular responses to aspirin in colonic organoids from African- and European-Americans.

Physiol Genomics

January 2025

Section of Gastroenterology, Hepatology and Nutrition, Department of Medicine, University of Chicago, Chicago, Illinois.

Aspirin (ASA) is a proven chemoprotective agent for colorectal cancer (CRC), though inter-individual responses and cellular mechanisms are not well characterized. Human organoids are ideal to study treatment responses across individuals. Here, colonic organoids from African-Americans (AA) and European-Americans (EA)were used to profile genomic and cellular ASA responses.

Platelets as crucial players in the dynamic interplay of inflammation, immunity, and cancer: unveiling new strategies for cancer prevention.

Front Pharmacol

December 2024

Systems Pharmacology and Translational Therapeutics Laboratory, The Center for Advanced Studies and Technology (CAST), "G. d'Annunzio" University, Chieti, Italy.

Inflammation plays a critical role in the pathogenesis of various diseases by promoting the acquisition of new functional traits by different cell types. Shared risk factors between cardiovascular disease and cancer, including smoking, obesity, diabetes, high-fat diet, low physical activity, and alcohol consumption, contribute to inflammation linked to platelet activation. Platelets contribute to an inflammatory state by activating various normal cells, such as fibroblasts, immune cells, and vascular cells.

PEGylated Platinum Nanoparticles: A Comprehensive Study of Their Analgesic and Anti-Inflammatory Effects.

ACS Appl Bio Mater

January 2025

Department of Physics and Electronics, Christ University, Bengaluru, Karnataka, India 560029.

Pain and inflammation are common symptoms of a majority of the diseases. Chronic pain and inflammation, as well as related dreadful disorders, remain difficult to control due to a lack of safe and effective medications. In this work, biocompatible platinum nanoparticles with significant analgesic and anti-inflammatory action were synthesized through a wet chemical method using polyethylene glycol-400 as a capping agent and sodium borohydride as a reducing agent.

Coronary atherosclerosis (or coronary heart disease [CHD]) is a common cardiovascular disease that seriously damages human health. Percutaneous coronary stent implantation represents the primary treatment option for severe CHD in clinical practice; meanwhile, dual antiplatelet therapy (DAPT) is widely used to reduce the risk of postoperative thrombosis. Although the mechanisms of action of the two most commonly used antiplatelet drugs, aspirin and clopidogrel, remain unclear, clinical studies have shown that some patients are susceptible to stent thrombosis-antiplatelet resistance (high on-treatment platelet reactivity [HTPR])-despite using these drugs.
