3-Hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitor (statins) is one of the most commonly prescribed agents for controlling hyperlipidemia. Apart from their lipid-lowering property, statins are well known for their pleiotropic effects, such as improvement of vascular endothelial dysfunction, attenuation of inflammatory responses, stabilization of atherosclerotic plaques, inhibition of vascular smooth muscle proliferation, and modulation of procoagulant activity and platelet function. The vasculo-protective effect of statins is mainly mediated by inhibition of the mevalonate pathway and oxidized low-density lipoprotein generation, thereby enhancing the biosynthesis of endothelium-derived nitric oxide. Accumulating clinical evidence strongly suggests that administration of statins reduces overall mortality, the development myocardial infarction and atrial fibrillation, and length of hospital stay after a major cardiac/noncardiac surgery. This review updates the clinical pharmacology and therapeutic applications of statins during major operations, and highlights the anesthesia considerations for perioperative statin therapy.

Primary aldosteronism (PA) is a common, salt-sensitive form of endocrine hypertension. Compared with essential hypertension (EH), PA is more susceptible to cardiorenal complications and metabolic risks. However, PA has a low screening rate and a poor response to mineralocorticoid receptor antagonists (MRAs).

Statins are crucial for both the prevention and management of atherosclerotic cardiovascular disease (ASCVD). However, even with optimized statin therapy, a significant residual risk of ASCVD remains, highlighting the need for innovative approaches to lipid-lowering therapies (LLT) that more effectively target low-density lipoprotein cholesterol (LDL-C) and other atherogenic lipoproteins. Recently, novel pharmacologic agents have been introduced for the management of dyslipidemia.

Background: Low-density lipoprotein cholesterol (LDL-C) has been determined as an established risk factor for acute ischemic stroke (AIS). Despite the recommendation for in-hospital initiation of high-intensity statin therapy in AIS patients, achieving the desired target LDL-C levels remains challenging. Evolocumab, a highly effective and quickly acting agent for reducing LDL-C levels, has yet to undergo extensively exploration in the acute phase of AIS.

We recently identified a tumor-cell autochthonous tumorigenic role for dimerization of the 4Ig isoform of B7-H3 (4Ig-B7-H3) [7], where 4Ig-B7-H3 dimerization activated tumor-intrinsic cellular proliferation and tumorigenesis pathways, providing a novel opportunity for therapeutic intervention. Herein, a live cell split-luciferase complementation strategy was used to visualize 4Ig-B7-H3 homodimerization in a high-throughput small molecule screen (HTS) to identify modulators of this protein-protein interaction (PPI).

Introduction: The progression of diabetes status in post-stroke patients remains under-investigated, particularly regarding new treatments for type II diabetes mellitus (DM II), like glucagon-like peptide 1 receptor agonists (GLP-1-RA) and sodium-glucose co-transporter-2 (SGLT-2) inhibitors, which have not been studied in the post-stroke setting.
Patients And Methods: Eight hundred eighty-four consecutive ischemic stroke patients recruited to our prospective STROKE-CARD Registry were assessed concerning their glycemic status at baseline (normoglycemia, prediabetes, DM II) and change over time within 1 year follow-up. Multivariate logistic regression was performed to identify factors associated with transitioning from normoglycemia to prediabetes or DM II.
