Abstract
BackgroundAtherosclerosis contributes to cognitive dysfunction and Alzheimer's disease-related pathologies. Atherogenic index of plasma (AIP) is a novel and composite biomarker can predict atherosclerosis.ObjectiveThis study aims to (1) examine the association between the AIP and cognitive performance, and (2) explore the mediating role of oxidative stress biomarkers in this relationship.Methods1466 participants over the age of 60 were included from 2011-2014 NHANES. AIP was calculated through log-transformed triglyceride to high-density lipoprotein cholesterol ratios. The assessment of cognition was conducted using the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) test. Weighted linear regression model and restricted cubic spline were carried out to determine the associations between AIP and CERAD scores. The mediation analyses were conducted to assess whether oxidative stress mediates the association.ResultsHigher AIP levels were associated with lower CERAD learning scores. The highest quartile of AIP showed a 0.67-fold decrease (95%CI: -1.30, -0.03; p = 0.041) on the CERAD total score than that in the lowest quartile. Each 1-unit increase in AIP corresponded to reductions in CERAD total and delayed recall scores of approximately 1.09 and 0.54 points, respectively, in the sub-population under 70 years. Moreover, 25(OH)D, an oxidative stress indicator, partially mediated 24% of the association between AIP and the CERAD total score.ConclusionsAIP has the potential to indicate the risk of cognitive aging, especially that for young-old or female older adults. The supplementation of 25(OH)D may reduce atherosclerosis-related cognitive decline, which could provide some strategies for the prevention of dementia.

Metabolites 2020; 11:metabo11010006.

Abstract
Personalized risk prediction for diabetic cardiovascular disease (DCVD) is at the core of precision medicine in type 2 diabetes (T2D). We first identified three marker sets consisting of 15, 47, and 231 tagging single nucleotide polymorphisms (tSNPs) associated with DCVD using a linear mixed model in 2378 T2D patients obtained from four population-based Korean cohorts. Using the genetic variants with even modest effects on phenotypic variance, we observed improved risk stratification accuracy beyond traditional risk factors (AUC, 0.63 to 0.97). With a cutoff point of 0.21, the discrete genetic liability threshold model consisting of 231 SNPs (GLT231) correctly classified 87.7% of 2378 T2D patients as high or low risk of DCVD. For the same set of SNP markers, the GLT and polygenic risk score (PRS) models showed similar predictive performance, and we observed consistency between the GLT and PRS models in that the model based on a larger number of SNP markers showed much-improved predictability. In silico gene expression analysis, additional information was provided on the functional role of the genes identified in this study. In particular, HDAC4, CDKN2B, CELSR2, and MRAS appear to be major hubs in the functional gene network for DCVD. The proposed risk prediction approach based on the liability threshold model may help identify T2D patients at high CVD risk in East Asian populations with further external validations.

Abstract
Diabetes mellitus (DM) is a common disease worldwide. There is a strong association between DM and neurovascular and neurodegenerative disorders. The first group mainly consists of diabetic retinopathy, diabetic neuropathy and stroke, whereas, the second group includes Alzheimer's disease, Parkinson's disease, mild cognitive impairment and dementia. The aforementioned diseases have a common pathophysiological background including insulin resistance, oxidative stress, atherosclerosis and vascular injury. The increasing prevalence of neurovascular and neurodegenerative disorders among diabetic patients has resulted in an urgent need to develop biomarkers for their prediction and/or early detection. The aim of this review is to present the potential application of the most promising biomarkers of diabetes-related neurodegenerative and neurovascular disorders, including amylin, β-amyloid, C-reactive protein (CRP), dopamine, gamma-glutamyl transferase (GGT), glycogen synthase kinase 3β, homocysteine, microRNAs (mi-RNAs), paraoxonase 1, phosphoinositide 3-kinases, tau protein and various growth factors. The most clinically promising biomarkers of neurovascular and neurodegenerative complications in DM are hsCRP, GGT, homocysteine and miRNAs. However, all biomarkers discussed in this review could become a part of the potential multi-biomarker screening panel for diabetic patients at risk of neurovascular and neurodegenerative complications.
