Background: Atherogenic index of plasma (AIP), a novel logarithmic index that combines fasting triglyceride and high-density lipoprotein cholesterol concentrations, is associated with the burden of atherosclerosis. This study aimed to evaluate the relationship between AIP and coronary artery disease (CAD) risk, severity, and prognosis in populations with and without established CAD.
Methods: PubMed, Embase, and Web of Science were systematically searched from the inception of each database to August 13, 2024. Cross-sectional studies, case-control studies, and prospective or retrospective cohort studies using multivariate analysis were included. Given that the true effect size may differ across studies, a random-effects model for all analyses was applied.
Results: Fifty-one observational studies were included in this study. Patients with higher AIP were more likely to have CAD (odds ratio (OR): 2.79, 95% CI 1.75-4.45, P < 0.00001). Furthermore, these patients were more likely to have coronary artery calcification (OR: 2.28, 95% CI 1.74-3.00, P < 0.00001), multivessel CAD (OR: 2.04, 95% CI 1.50-2.77, P < 0.00001), and an increased risk of plaque progression (OR: 1.49, 95% CI 1.17-1.91, P = 0.001). In populations without established CAD, higher AIP levels were associated with an increased risk of Major adverse cardiovascular events (MACE) (hazard ratio (HR): 1.28, 95% CI 1.22-1.35, P < 0.00001). Interestingly, this finding was consistent in patients presenting with acute coronary syndrome (HR: 1.59, 95% CI 1.33-1.89, P < 0.00001) and patients with chronic coronary syndrome or stable CAD (HR: 1.65, 95% CI 1.15-2.37, P = 0.007).
Conclusions: This meta-analysis demonstrates that elevated AIP is strongly associated with increased CAD risk, greater severity, and poorer prognosis in populations with and without established CAD. However, more studies are needed to evaluate the predictive performance and determine the optimal cut-off for AIP in different populations.

High-fat (HF) diets contribute to obesity, insulin resistance, fatty liver, gut microbiota dysbiosis, oxidative stress, and low-grade chronic inflammation. This study evaluated the preventive effects of dietary Type 2 resistant starch (RS2) from high-amylose maize and low-dose d-fagomine (FG) from buckwheat on these metabolic disturbances. Male Wistar-Kyoto rats (9-10 weeks old) were assigned to four diet groups for 10 weeks: standard (STD) diet, HF diet (45% kcal from fat), HF + RS diet (15% RS2), and HF + FG diet (0.

Background: Musculoskeletal disease (MSD), including osteoarthritis, rheumatoid arthritis, osteoporosis, and sarcopenia, poses a serious social burden. While physical activity (PA) benefits musculoskeletal health, the optimal PA level for MSD prevention remains unclear. Clarifying risk factors and biological mechanisms is essential.

Aim: The relationship between insulin resistance and atherosclerosis in euthyroid Hashimoto’s thyroiditis (HT) remains unclear. This study aimed to compare the atherogenic index of plasma (AIP) and triglyceride–glucose (TyG) index between patients with euthyroid HT and healthy controls.
Materials And Methods: This retrospective cross-sectional study examined 1,000 patients aged 18–50 who visited the internal medicine outpatient clinic at Mersin City Training and Research Hospital between January 1, 2020, and June 1, 2022.

Purpose: We previously identified a dietary pattern (DP) associated with plasma trimethylamine -oxide (TMAO) and choline, the TMAO-DP, where higher scores represent more atherogenic potential of the diet. The mechanisms linking dietary intake to the presence of choline and TMAO in the plasma, and by which TMAO may influence atherosclerosis in humans require further clarification. The objective was to evaluate associations between the TMAO-DP and metabolomic profiles in postmenopausal women from the Women’s Health Initiative (WHI).

Objectives: Natural products like Aronia () are promising candidates to manage metabolic abnormalities due to their bioactive compounds. This study aimed to evaluate the effects of daily Aronia fruit extract supplementation on the components of Metabolic Syndrome (MetS), cardiovascular health, inflammation, and atherogenic markers in elderly patients.
Methods: Our study is a randomized controlled trial of 44 subjects (12 males and 32 females) diagnosed with MetS.
