Background: The triglyceride glucose (TyG) index reflects insulin resistance; the latter being associated with mild cognitive impairment (MCI).
Objective: To investigate the clinical value of the TyG index to identify MCI in patients living with type 2 diabetes (T2D) using a cross-sectional study.
Methods: This cross-sectional study was performed on 517 patients with T2D. The diagnosis of MCI was based on criteria established by the National Institute on Aging-Alzheimer's Association workgroup, and patients were divided into the MCI group and the normal cognitive function (NCF) group. The logistic regression analysis determines whether the TyG index is related to MCI. Subsequently, we constructed the receiver operating characteristic curve (ROC) and calculated the area under the curve (AUC). The nomogram model of the influence factor was established and verified.
Results: Compared to the type 2 diabetes-normal cognitive function (T2D-NCF) group, the MCI subjects were olderand had higher TyG indexes, lower cognitive scores, and lower education levels (p < 0.01). After adjusting for the confounders, the TyG index was associated with MCI (OR = 7.37, 95% CI = 4.72-11.50, p < 0.01), and TyG-BMI was also associated with MCI (OR = 1.02, 95% CI = 1.01-1.02, p<0.01). The TyG index AUC was 0.79 (95% CI = 0.76-0.83). The consistency index of the nomogram was 0. 83[95% CI (0. 79, 0. 86)].
Conclusion: Our results indicate that the TyG index and TyG-BMI are associated with MCI in T2D patients, and the TyG index is an excellent indicator of the risk of MCI in T2D patients. The nomogram incorporating the TyG index is useful to predict MCI risk in patients with T2D.

Introduction: Berberine (BBR) has the characteristics of repressing hyperglycemia, obesity, and inflammation, as well as improving insulin resistance. However, the underlying mechanism remains to be fully understood. This study explores whether BBR regulates inositol requiring enzyme 1 (IRE1)/glycogen synthase kinase 3 beta (GSK-3β) axis to resist obesity-associated inflammation, thereby improving glucolipid metabolism disorders.

Background: Metabolic syndrome (MetS) involves having at least 3 out of 5 health conditions that increase the risk of cardiovascular disease, stroke, and type 2 diabetes mellitus. These conditions include increased blood pressure (BP), high blood sugar, excess body fat around the waist, and abnormal cholesterol or triglyceride levels. Each of these conditions is treatable with lifestyle changes and/or medication.

Background: As a novel oral anti-hyperglycemic agent, sodium-glucose cotransporter 2 inhibitors (SGLT2-i) have been demonstrated to improve cardiovascular outcomes in acute myocardial infarction (AMI) patients with type 2 diabetes mellitus (T2DM). However, the mechanism responsible for the beneficial effects remains unclear. Recently, extensive studies have demonstrated a close relationship between elevated fasting triglyceride-glucose (TyG) index and the risk of AMI.

Background And Aims: To explore the predictive value of the triglyceride-glucose(TyG)index combined with non-high-density lipoprotein cholesterol (Non-HDL-C) in coronary atherosclerotic heart disease (CHD).
Methods And Results: We retrospectively collected patients who were suspected of CHD and underwent coronary angiography in Yiwu Central Hospital and collected medical history, other serum biochemical evaluation and echocardiography from the enrolled population, Non-HDL-C and TyG indices were calculated, and their correlation with Gensini score was analyzed. Logistic regression analysis was used to analyze the risk factors of coronary heart disease, and ROC curves were plotted to assess the predictive value of CHD in subjects with single or multiple indices.
