Small dense LDL particles (B phenotype) are considered to be more atherogenic than large buoyant LDL particles. The influence of glycemic control on LDL particle size and density is still under debate. The aim of this study was to determine LDL subfraction phenotype in both IDDM and NIDDM patients in poor glycemic control compared with that of respective matched control groups. In addition, we evaluated the effect of a 3-month period of optimized glycemic control on this parameter. Thirty-seven IDDM patients and 33 NIDDM patients, together with two respective age-, sex-, and BMI-matched control groups were studied. Non-A phenotype prevalence in IDDM patients before (19%) and after blood glucose optimization (11%) was similar to that of their control group (12%). However, NIDDM patients displayed a higher proportion of the non-A phenotype (51%) than did the control group (28%), but it became closer (30%, P < 0.05) after glycemic control improved. All subjects with non-A phenotype that changed to A phenotype showed triglyceride levels below 1.63 mmol/l and a greater decrease in HbA1c than did subjects whose phenotype did not change (4.9 +/- 1.5 vs. 3.1 +/- 1.4%, P < 0.05). A higher proportion of small dense LDL was observed in NIDDM women than in nondiabetic women (LDL5 10.0 +/- 4.8 vs. 6.3 +/- 1.5%, LDL6 6.1 +/- 2.2 vs. 4.2 +/- 0.8%, P < 0.05) during both stages of glycemic control, but no differences were observed between NIDDM and nondiabetic men. In conclusion, these findings provide new evidence for the relevance of near-normal glycemic control in the prevention of macrovascular disease and could contribute to an explanation of the loss of protection for cardiovascular disease in diabetic women.

Background: It has been revealed that the potential utility of the triglycerides and glucose (TyG) index as an effective option for assessing glycemic control; however, evidence in this field is still scarce.
Aims: The goal of this study was to investigate the diagnostic accuracy of the TyG index, as an alternative option, to detect inadequate glycemic control in patients with type 2 diabetes (T2D).
Methods: Men and women between 30 and 60 years of age diagnosed with type 2 diabetes were included in a cross-sectional study.

Patients with diabetes are at increased risk of HBV infection; however, the effects of HBV infection and anti-HBV therapy on the management of type 1 diabetes (T1D), type 2 diabetes (T2D), and latent autoimmune diabetes in adults (LADA) remain unclear. From 2016 to 2023, we recruited a multicenter cohort of 355 HBV-infected inpatients, including 136 with T1D, 140 with T2D, and 79 with LADA. The control group included 525 HBV-uninfected inpatients, comparing 171 with T1D, 204 with T2D and 150 with LADA.

In mice, reducing dietary levels of the branched-chain amino acids (BCAAs) recapitulates many of the benefits of a low protein diet; BCAA-restricted diets extend lifespan, reduce frailty, and improve metabolic health, while BCAA supplementation shortens lifespan, promotes obesity, and impairs glycemic control. Recently, high protein diets have been shown to promote cellular senescence, a hallmark of aging implicated in many age-related diseases, in the liver of mice.

Zinc is one of the elements that play a part in insulin secretion and signaling. Therefore, this study seeks the answer to the following question: "What are the effects of 220 mg zinc sulfate supplementation on the weight, blood pressure, and glycemic control of patients with Type 2 diabetes?".

Objective: The objective of the study was to estimate the pleiotropic effect of teneligliptin on high-sensitivity C-reactive protein (hs-CRP) levels and some cardiorenal parameters in comparison to glimepiride, both as add-on therapy to metformin.
Methodology: This 12-week open-label, parallel-group, randomized controlled trial was conducted among Indian people with type 2 diabetes mellitus and on metformin monotherapy with poor glycemic control (glycated hemoglobin >7% or 53 mmol/mol). The endpoints were mean change in hs-CRP levels, systolic blood pressure (SBP), diastolic blood pressure (DBP), serum creatinine, blood urea, estimated glomerular filtration rate (eGFR), and change in cardiovascular (CV) risk categories from baseline to end of 12 weeks.
