Purpose: The goal of this meta-analysis was to establish whether statin treatment reduces Lp-PLA2 mass concentration and/or activity.

Methods: PubMed, Scopus, Web of Science, ClinicalTrials.gov, and Google Scholar databases were searched using MESH terms and keywords. Randomized controlled trials (RCT) with either parallel or cross-over design examining the effect of statins on Lp-PLA2 mass and/or activity were included in meta-analysis.

Results: Out of 256 articles, 10 RCT were selected for meta-analysis. Statin therapy significantly reduced both Lp-PLA2 mass (WMD -44.46 ng/mL; 95%CI -59.01, -29.90; p < 0.001; I = 93%) and activity (WMD -39.37 nmol/min/mL; 95%CI -69.99, -8.75; p = 0.01; I = 100%). The sensitivity analysis was robust for Lp-PLA2 mass and was also positive for two studies concerning Lp-PLA2 activity.

Conclusion: Statin therapy significantly reduced both Lp-PLA2 mass and activity.

Objective: This study aimed to analyse the association between lipoprotein-associated phospholipase A2 (Lp-PLA2) and 25-hydroxy-vitamin D (25[OH]D) and early diabetic kidney disease (DKD) in patients with type 2 diabetes mellitus (T2DM) and evaluate the potential roles of these two biomarkers in the clinical diagnosis of DKD.

Methods: A total of 422 inpatients with T2DM were retrospectively enrolled between January 2018 and March 2022 at the First Affiliated Hospital of Nanjing Medical University. The baseline clinical parameters of each patient were determined, and their demographic characteristics were extracted from the hospital information system.

This paper aimed to investigate the effects of exercise on hepatic platelet-activating factor (PAF) metabolism in rats fed a high-fat diet. Thirty-two male Sprague-Dawley (SD) rats were divided into control group (C), high-fat diet group (H), exercise group (EC), and high-fat diet+exercise group (EH). Serum lipids, glucose, insulin and markers of hepatic injury after a 16-week dietary and/or exercise intervention (60 min/day, 6 times/week) were measured by biochemical analysis; liver lipidomic profiles were analyzed by liquid chromatograph-mass spectrometer (LC-MS).

Introduction: The potential utility of inflammatory and hemodynamic plasma biomarkers for the prediction of incident lower extremity arterial disease (LEAD), carotid artery stenosis (CAS), isolated atherosclerotic disease without concomitant abdominal aortic aneurysm (AAA), and isolated AAA without concomitant atherosclerotic disease has not yet been integrated in clinical practice. The main objective of this prospective study was to find predictive plasma biomarkers for cardiovascular disease and to evaluate differences in plasma biomarker profiles between asymptomatic and symptomatic CAS, as well as between isolated atherosclerotic disease and isolated AAA.

Methods: Blood samples collected at baseline from participants in the prospective Malmö Diet and Cancer study (MDCS) cardiovascular cohort (n = 5550 middle-aged individuals; baseline 1991-1994) were used for plasma biomarker analysis.

Background: Sarcopenia, characterized by progressive muscle dysfunction, is a common complication of chronic obstructive pulmonary disease (COPD). Our previous study revealed serum Lipoprotein-associated phospholipaseA2 (Lp-PLA2) level significantly increased in COPD and associated with exercise tolerance. This study further investigated the functions and target potential of Lp-PLA2 for sarcopenia in COPD.
