Background: The triglyceride glucose index (TyG) has previously been considered a reliable indicator of insulin resistance (IR) and an independent prognostic predictor in heart failure (HF).
Objectives: To clarify the association between the TyG and short-term death in non-diabetic patients admitted for acute heart failure (AHF).
Material And Methods: We examined 886 out of 1620 consecutive AHF patients who were admitted to Shunde Hospital, Southern Medical University, Foshan, China, from June 1, 2014, to June 1, 2022. The median of the patientsf TyG values was used to divide them into 2 groups. The following formula was used to calculate the TyG: ln [fasting triglycerides (mg/dL) ~ fasting glucose (mg/dL)/2]. The data on all-cause mortality of AHF patients during their hospital stay were collected. The 30-day Enhanced Feedback for Effective Cardiac Treatment (EFFECT) death risk score was used to assess the risk of death.
Results: The TyG level was positively correlated with a poor AHF prognostic marker (N-terminal B-type natriuretic peptide (NT-proBNP)) (Ď = 0.207, p < 0.001) and negatively correlated with a protective marker (serum albumin) (Ď = .0.43, p < 0.001). Higher TyG values were associated with an elevated EFFECT score and hospital mortality (p < 0.001). According to multivariate logistic regression analysis, higher TyG levels raised the risk of death in hospital (odds ratio (OR) = 1.73; 95% confidence interval (95% CI): 1.03.3.27; p = 0.031) after adjusting for multiple variables, including age, EFFECT score and NT-proBNP. The TyG had a greater area under the receiver operating characteristic (ROC) curve (AUC: 0.688) for predicting hospital death compared to NT-proBNP (AUC: 0.506).
Conclusions: Our findings show that the TyG is associated with the short-term mortality rate of non-diabetic patients admitted to the hospital for AHF. The TyG testing could be a useful prognostic indicator for these patients.

Insulitis and exocrinitis in autoantibody-positive non-diabetic individuals: role of HLA genotypes.
J Clin Endocrinol Metab
January 2025
Université Paris Cité, Institut Cochin, CNRS, INSERM, Paris, France.
Context: Type 1 diabetes (T1D) is characterized by the presence of autoantibodies on a genetic background largely determined by HLA class II haplotypes. Stage 1 T1D is characterized by the presence of multiple autoantibodies and normoglycemia.
Objective: To investigate the prevalence of high-risk HLA-DQB1 haplotypes and the extent of islet autoimmunity in pancreatic tissues from non-diabetic organ donors with autoantibodies.
Associations between circulating amino acids and metabolic dysfunction-associated steatotic liver disease in individuals living with severe obesity.
Physiol Rep
February 2025
Quebec Heart and Lung Institute - Laval University, Quebec, Quebec, Canada.
Metabolic dysfunction-associated steatotic liver disease (MASLD) describes liver diseases caused by the accumulation of triglycerides in hepatocytes (steatosis) as well as the resulting inflammation and fibrosis. Previous studies have demonstrated that accumulation of fat in visceral adipose tissue compartments and the liver is associated with alterations in the circulating levels of some amino acids, notably glutamate. This study aimed to investigate the associations between circulating amino acids, particularly glutamate, and MASLD.

This systematic review evaluates the success rates of dental implants in patients with type 2 diabetes mellitus, focusing on outcomes such as implant survival, marginal bone loss, and peri-implant biomarkers. A comprehensive literature search was conducted across multiple databases, including PubMed, Cochrane, Embase, Scopus, and Web of Science, to identify relevant systematic reviews and meta-analyses. Four studies were included, encompassing diverse populations and interventions.

Pupillary dynamics in diabetic and nondiabetic patients following uneventful phacoemulsification.
Clin Exp Optom

Department of Ophthalmology, Gaziantep City Hospital, Gaziantep, Turkey.
Clinical Relevance: Although laser refractive surgeries and multifocal intraocular lens implantation are generally avoided in patients with diabetic retinopathy, a substantial proportion of well-glycaemic-controlled type 2 diabetes mellitus patients are considered for these procedures. Pupil dynamics play a significant role in determining postoperative satisfaction in these patients.
Background: To evaluate pupillary dynamics in patients with and without diabetes following uneventful phacoemulsification surgery.
