Insulin resistance and hypersecretion in obesity. European Group for the Study of Insulin Resistance (EGIR).
TLDR
In nondiabetic, normotensive obese subjects, the prevalence of insulin resistance is relatively low, and is exceeded by the prevalenceOf insulin hypersecretion, particularly in women with central obesity, in the obese with preserved insulin sensitivity.
Postprandial hyperglycemia in patients with noninsulin-dependent diabetes mellitus. Role of hepatic and extrahepatic tissues.
TLDR
Excessive hepatic glucose release and impaired glucose uptake are involved in the pathogenesis of postprandial hyperglycemia in patients with NIDDM.
Tight blood pressure control and risk of macrovascular and microvascular complications in type 2 diabetes: UKPDS 38
TLDR
Tight blood pressure control in patients with hypertension and type 2 diabetes achieves a clinically important reduction in the risk of deaths related to diabetes, complications related to Diabetes, progression of diabetic retinopathy, and deterioration in visual acuity.
Sex hormone binding globulin and insulin resistance
TLDR
Genetic studies using Mendelian randomization analysis linking three single nucleotide polymorphisms of the SHBG gene to risk of developing type 2 DM suggest SHBG may have a role in the pathogenesis of type 1 DM and several potential mechanisms may account for this association.
Efficacy of atenolol and captopril in reducing risk of macrovascular and microvascular complications in type 2 diabetes: UKPDS 39
TLDR
This study provided no evidence that either drug has any specific beneficial or deleterious effect, suggesting that blood pressure reduction in itself may be more important than the treatment used.
Beta‐cell deterioration determines the onset and rate of progression of secondary dietary failure in Type 2 diabetes mellitus: the 10‐year follow‐up of the Belfast Diet Study
TLDR
A 10‐year prospective natural history study of 432 newly diagnosed diabetic patients undertaken to assess the effect of intensive dietary management, where patients were transferred to insulin, or oral hypoglycaemic therapy (tolbutamide, metformin) by predetermined criteria of weight and plasma glucose found no change in mean insulin sensitivity in any of the groups.
Inhibition of dipeptidyl peptidase IV activity by oral metformin in Type 2 diabetes
TLDR
This work investigated the acute effects of metformin on DPP IV activity in Type 2 diabetes to elucidate inhibition of DPPIV as a possible mechanism of action.
Effect of Eucaloric High- and Low-Sucrose Diets With Identical Macronutrient Profile on Insulin Resistance and Vascular Risk
TLDR
A high-sucrose intake as part of an eucaloric, weight-maintaining diet had no detrimental effect on insulin sensitivity, glycemic profiles, or measures of vascular compliance in healthy nondiabetic subjects.
Insulin action and insulin secretion in polycystic ovary syndrome treated with ethinyl oestradiol/cyproterone acetate.
TLDR
Despite considerable improvement in androgen profile, treatment with ethinyl oestradiol/cyproterone acetate did not alter insulin action in PCOS, and this insulin resistance does not appear to be determined by insulin pulse frequency.
Investigation of the effect of oral metformin on dipeptidylpeptidase‐4 (DPP‐4) activity in Type 2 diabetes 1
TLDR
This work investigated the acute effects of metformin with and without food on DPP‐4 activity in Type 2 diabetes.
