Objective: Arteriovenous fistula (AVF) structures are vital formations used for hemodialysis. Diabetes mellitus (DM) is a critical disease affecting the vascular system. The triglyceride glucose (TyG) index has been shown to be associated with major adverse cardiovascular events in patients with Type 2 DM. In this study, we aimed to investigate the effect of the TyG index on the primary AVF patency of diabetic patients.
Patients And Methods: Between March 2018 and March 2023, patients with DM who underwent AVF surgery in our clinic due to end-stage renal disease were retrospectively included in this study. The patients who could receive hemodialysis were determined as Group 1, and those who could not were determined as Group 2.
Results: A total of 189 patients were included in the study. Those who did not develop AVF primary failure were included in Group 1 [n=138, median age = 59 (22-77) years], and those who did were included in Group 2 [n=51, median age = 63 (20-81) years]. In the multivariate analysis, age >70 years (OR: 0.871, 95% CI: 0.594-0.983, p=0.039), the presence of PAD (OR: 0.582, 95% CI: 0.0.458-0.896, p=0.046), and TyG index (OR: 0.879, 95% CI: 0.591-0.916, p<0.001) were determined as independent predictors for primary AVF failure.
Conclusions: This study demonstrated that the TyG index value, calculated from blood samples taken at the time of hospital admission in hemodialysis patients with diabetes mellitus (DM), is an independent predictor of primary AVF failure following AVF surgery.

Background: Triglyceride-glucose (TyG) related indices, which serve as simple markers for insulin resistance, have been closely linked to metabolic dysfunction-associated steatotic liver disease (MASLD), cardiovascular disease (CVD), and mortality. However, the prognostic utility of TyG-related indices in predicting the risk of CVD and mortality among patients with MASLD remains unclear.
Methods: Data of 97,331 MASLD patients, with a median age of 58.

Background: The triglyceride-glucose (TyG) index is now widely recognized as a marker of insulin resistance and has been linked to the development and prognosis of atherosclerotic cardiovascular diseases (ASCVD) in numerous populations, particularly in the Eastern world. Although there are fewer reports from the Western world, and they are sometimes contradictory, the absence of definitive data on the relationship between a raised TyG index and cardiovascular risk suggested the opportunity of testing this biochemical marker against a well-established vascular marker such as the carotid intima media thickness (c-IMT).
Methods: Primary prevention patients were selected from a cohort of individuals who underwent c-IMT measurement between 1984 and 2018 at the Dyslipidemia Center at the ASST Grande Ospedale Metropolitano Niguarda in Milan, Italy.

Background: Depression and cognitive impairments are prevalent among older adults, with evidence suggesting potential links to obesity and lipid metabolism disturbances. This study investigates the relationships between the triglyceride-glucose (TyG) index, body mass index (BMI), depression, and cognitive dysfunction in older adults, leveraging data from the NHANES survey and employing machine learning techniques.
Methods: We analysed 1352 participants aged 60-79 from the 2011-2014 NHANES dataset, who underwent cognitive function testing, depression assessments, and TyG index measurements.

Fatty liver impairs liver function and reduces productivity in dairy cows. Our previous in vivo findings demonstrated that branched-chain amino acids (BCAA) or branched-chain ketoacid (BCKA) improved liver function and lactation performance in dairy cows; however, the underlying mechanisms remain unclear. This study aimed to assess the impact of BCAA or BCKA supplementation on intracellular triglyceride (TG) accumulation, lipid metabolism, antioxidant response, and apoptosis in hepatocytes.
