Abstract

To investigate the correlation between the frequency of dawn phenomenon and obesity in patients with type 2 diabetes. This study was conducted in 98 patients with type 2 diabetes admitted to the Metabolic Disease Hospital of Tianjin Medical University from 2011 to 2014. The subjects were divided into 3 groups according to BMI: the normal weight (BMI 18.5-23.9 kg/m(2), n = 30), the overweight(BMI 24-27.9 kg/m(2), n = 33)and the obesity (BMI ≥ 28.0 kg/m(2), n = 35). All participants underwent continuous glucose monitoring for 72 h. Fasting plasma glucose(FPG), insulin and C-peptide were tested. Frequency of dawn phenomenon among the 3 groups was calculated, and the correlations between dawn phenomenon and its related factors were analyzed. The frequency of dawn phenomenon in type 2 diabetes increased with the increase of BMI in the 3 groups (P < 0.05) with 33.3% in the normal weight, 78.8% in the overweight and 88.6% in the obesity groups, respectively. The dawn phenomenon was positively correlated with BMI (r = 0.424, P < 0.05), Homeostasis model assessment of insulin resistance(HOMA-IR) (r = 0.781, P < 0.05), waist circumference (r = 0.394, P < 0.05), fasting C-peptide (r = 0.254, P < 0.05)and TG (r = 0.220, P < 0.05). It was n...Continue Reading

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
