EXPRESS: Dual Versus Triple Antithrombotic Therapy in Atrial Fibrillation and Acute Coronary Syndrome: An Updated Meta-Analysis of Randomized Controlled Trials.
Antithrombotic treatment in patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) poses a dilemma. We compared outcomes of dual antithrombotic therapy (DAT) (direct oral anticoagulants (DOACs)/warfarin + antiplatelets) vs triple antithrombotic therapy (TAT) (DOACs/warfarin, aspirin, and P2Y12 inhibitor) in this population. Multiple databases were searched from inception to December 17, 2023 to identify randomized controlled trials (RCTs) comparing DAT vs TAT in patients with AF and ACS. ⋯ No difference was seen in the occurrence of MACE, MI, stroke, or stent thrombosis between DAT and TAT across all three durations of TAT. This is the largest pooled analysis comparing TAT to DAT stratified by the duration of antithrombotic therapy. Our results revealed that DAT was associated with reduced bleeding risk despite no difference in other outcomes.

Clinical research is a key factor in healthcare progress, as it contributes toward improving our knowledge on the prevention, etiology, and treatment of different conditions. Healthcare professionals and researchers should be familiar with this specific terminology and procedures of clinical research to understand and be able to evaluate clinical trial results and make decisions using up-to-date recommendations. ⋯ Additionally, when it comes to communicating the results and publishing them, it is also necessary to know how to do it adequately to ensure transparency. This work includes a description of different concepts commonly used in clinical research, particularly in the clinical trials field, in an attempt to compile different topics by providing a brief and accessible overview.

Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal hematopoietic stem cell disease. Clinical manifestations include intravascular hemolysis, renal dysfunction, fatigue, jaundice, pulmonary hypertension, and so on. Renal injury, as a clinical feature of PNH, is difficult to diagnose and is one of the causes of death in patients with PNH. This article reviews the progress in research on PNH combined with renal injury to improve clinicians' understanding of renal injury in PNH patients, define and judge staging in a timely and accurate manner, enable patients to receive timely and appropriate treatment and reduce mortality.

Iron is an essential element for the biological processes of living organisms, including the production of crucial oxygen-carrying proteins, formation of heme enzymes, and playing roles in electron transfer and oxidation-reduction reactions. It plays a significant role in various cardiovascular functions, including bioenergetics, electrical activity, and programmed cell death. Minor deficiencies of iron have been found to have negative impact on cardiovascular function in patients with heart failure (HF). ⋯ Large, randomized trials and meta-analysis, like Ferinject Assessment in patients with ID and chronic HF, AFFIRM-AHF, IRONMAN, and HEART-FID have demonstrated the efficacy of IV iron supplementation with IV ferric carboxymaltose or IV ferric derisomaltose in reducing hospitalizations and improving quality of life in patients with Heart Failure with reduced ejection fraction (HFrEF), New York Heart Association (NYHA) II-III. However, survival and mortality have demonstrated no improvement during acute exacerbations of HF or in outpatient management. The potential benefits of IV iron across the entire HF spectrum and its interaction with other HF therapies remain areas of interest for further research.

Hepatocellular carcinoma (HCC) is a prevalent form of primary liver cancer with a 5-year survival rate of just 18%. Ferulic acid, a natural compound found in fruits and vegetables such as sweet corn, rice bran, and dong quai, is an encouraging drug known for its diverse positive effects on the body, including anti-inflammatory, anti-apoptotic, and neuroprotective properties. Our study aimed to investigate the potential antitumor effects of ferulic acid to inhibit tumor growth and inflammation of HCC in rats. ⋯ In conclusion, ferulic acid is believed to possess antitumor properties by inhibiting HCC-induced hypoxia through the suppression of HIF-1α expression. Additionally, it helps in reducing the expression of mTOR, STAT3, cMyc, and cyclin D1, thereby slowing down tumor growth. Lastly, ferulic acid reduced hepatic tissue inflammation by downregulating NFκB and TNF-α.
