Introduction: This study evaluated the effects of diabetes mellitus (DM) on the nanostructure of root canal dentin using high-resolution transmission electron microscopy (HRTEM) and inductively coupled plasma mass spectrometry (ICP-MS).
Methods: Twenty extracted human premolars from diabetic and nondiabetic patients (n = 10 in each group) were decoronated and sectioned horizontally into 40 2-mm-thick dentin discs, with each disc designated for a specific test. ICP-MS was used to determine the different elemental levels of copper, lithium, zinc, selenium, strontium, manganese, and magnesium in diabetic and nondiabetic specimens. HRTEM was used to analyze the shape and quantity of the apatite crystals in diabetic and nondiabetic dentin at the nanostructural level. Statistical analysis was performed using Kolmogorov-Smirnov and Student t test (P < .05).
Results: ICP-MS revealed significant differences in trace element concentrations between the diabetic and nondiabetic specimens (P < .05), with lower levels of magnesium, zinc, strontium, lithium, manganese, and selenium (P < .05), and higher levels of copper in diabetic specimens (P < .05). HRTEM revealed that diabetic dentin exhibited a less compact structure with smaller crystallites and significantly more crystals in the 2500 nm area (P < .05).
Conclusion: Diabetic dentin exhibited smaller crystallites and altered elemental levels more than nondiabetic dentin, which could explain the higher root canal treatment failure rate in diabetic patients.

Purpose: Pancreatectomy patients often experience challenging fluctuations in blood glucose levels; therefore, they require a reliable monitoring system. This study aimed to determine the accuracy and acceptability of a continuous glucose monitoring (CGM) system compared with the intermittent capillary glucose test in patients who have undergone pancreatectomy.
Methods: Thirty non-diabetic pancreatectomy patients participated.

The Kynurenine pathway is crucial in metabolizing dietary tryptophan into bioactive compounds known as kynurenines, which have been linked to glucose homeostasis. The aryl hydrocarbon receptor (AhR) has recently emerged as the endogenous receptor for the kynurenine metabolite, kynurenic acid (KYNA). However, the specific role of AhR in pancreatic β-cells remains largely unexplored.

SGLT2 inhibitors are a family of drugs that were developed to treat diabetes mellitus. In randomized controlled trials, SGLT2 inhibitors seem to prevent kidney deterioration in patients with nephropathies, both diabetic and non-diabetic. However, in contrast to biochemical/physiological results (proteinuria and serum creatinine levels) that improve in all studies, the clinical results (all-cause mortality, cardiovascular death, need for dialysis, or renal transplant) do not consistently improve.

Background: Diabetic population are at an increased risk of developing dyslipidemia and other cardiovascular complications. The study was performed to evaluate the lipid profile parameter in the diabetic population among the ethnic tribal community of Tripura and calculate the risk of cardiovascular events. The tribal community was chosen as the study population because their lifestyle, food habits, culture and housing practices are different from people living on the plains.

Atrial fibrillation (AF) is the most common cause of arrhythmia-induced cardiomyopathy. Effective management strategies include medical therapy for rate and rhythm control, catheter ablation (CA), and goal-directed medical therapy. Sodium-glucose co-transporter 2 inhibitors (SGLT2i), a novel class of antidiabetic drugs, have shown a promising impact in reducing cardiovascular events in diabetic and nondiabetic heart failure (HF) patients.
