Background: Early diagnosis and treatment of type 2 diabetes can delay the onset of microvascular and macrovascular complications. Therefore, the identification of a novel biomarker for diagnosing diabetes is necessary. In the present study, the role of serum soluble leucine-rich repeats and immunoglobulin like domains 2 (sLRIG2) was investigated as a diagnostic biomarker of type 2 diabetes.
Methods: A total of 240 subjects with newly diagnosed type 2 diabetes (n=80), prediabetes (n=80), or normal glucose tolerance (NGT; n=80) were included in this study. The fasting serum sLRIG2 level was measured using a quantitative sandwich enzyme immunoassay technique with an enzyme-linked immunosorbent assay (ELISA). Serum sLRIG2 levels were compared among the three groups, and the associations of serum sLRIG2 levels with clinical variables were investigated.
Results: Serum sLRIG2 levels were significantly higher in subjects with type 2 diabetes (16.7±8.0 ng/mL) than in subjects without diabetes (NGT group: 12.3±5.3 ng/mL, P<0.001; prediabetes group: 13.2±5.8 ng/mL, P=0.002). Glycosylated hemoglobin (HbA1c: r=0.378, P<0.001) and blood glucose (fasting: r=0.421, P<0.001; 2-hour postprandial: r=0.433, P<0.001) correlated more strongly with sLRIG2 than any other clinical variables.
Conclusions: The serum sLRIG2 levels correlated with glucose parameters; thus, sLRIG2 might be a novel diagnostic biomarker for type 2 diabetes.

Diabetes mellitus, characterized by insufficient insulin secretion and impaired insulin efficacy, disrupts carbohydrate, protein, and lipid metabolism. The global diabetic population is expected to double by 2025, from 380 million, posing a significant health challenge. Most diabetic individuals fall into the type 1 or type 2 categories, and diabetes adversely affects various organs, such as the kidneys, liver, nervous system, reproductive system, and eyes.

Sedentary lifestyles and prolonged physical inactivity are often linked to poor mental and physical health as well as an increased risk of a number of chronic illnesses, including cancer, obesity, type 2 diabetes, and cardiovascular problems. Metabolic Syndrome (MetS), as the new disease, has emerged as the world's leading cause of illness. Despite having its roots in the West, this issue has now completely globalized due to the development of the Western way of life throughout the world.

Diabetes mellitus, particularly type 2 diabetes mellitus (T2DM), poses a significant global health challenge. Traditional management strategies primarily focus on glycemic control; however, there is a growing need for comprehensive approaches addressing the complex pathophysiology of diabetes complications. The recent study by Attia explores the potential of a novel therapy combining metformin with cholecalciferol (vitamin D3) and taurine to mitigate T2DM-related complications in a rat model.

Background: At present, the existing internal medicine drug treatment can alleviate the high glucose toxicity of patients to a certain extent, to explore the efficacy of laparoscopic jejunoileal side to side anastomosis in the treatment of type 2 diabetes, the report is as follows.
Aim: To investigate the effect of jejunoileal side-to-side anastomosis on metabolic parameters in patients with type 2 diabetes mellitus (T2DM).
Methods: We retrospectively analyzed the clinical data of 78 patients with T2DM who were treated jejunoileal lateral anastomosis.
