Introduction: Gestational diabetes mellitus (GDM) is the metabolic disorder most frequently associated with pregnancy, presenting important maternal and fetal implications. Strict glycemic control through lifestyle measures and/or pharmacotherapy is essential to achieve adequate obstetric-perinatal results. The objective of this study is to compare baseline characteristics and perinatal results in patients diagnosed with GDM after performing oral glucose tolerance test (OGTT) ...

Objective: To evaluate changes in gut microbiota induced by treatment in patients with gestational diabetes mellitus (GDM) treated with insulin in comparison to those treated with metformin.Material and methods: Thirty-one patients with GDM not controlled by diet, included in MeDiGes study (‘Efficacy of metformin in gestational diabetes not controlled by diet in comparison to insulin’), were aleatorized to receive insulin (n=14) or met...

Objectives: Some authors have defined subtypes within gestational diabetes (GD) based on the calculation, from glucose and insulin levels during oral glucose overload (OGTT), of indices of insulin sensitivity (Matsuda) and insulin secretion (Stumvoll). Powe et al [1] found that 30% of women with GD had predominantly low insulin secretion, 51% low insulin sensitivity and 18% both (mixed). The aim of this work is to analyze the correlation of these indices with other kn...

Introduction: Obesity is associated with an increasing risk of diabetes and atherosclerosis. Previous studies in animals show that oxidized low-density lipoprotein (Ox-LDL) can be captured by the adipocyte through different scavenger receptors (SR) and thus contribute to the worsening of insulin resistance (IR). We analyze the association between Ox-LDL levels and different SR present in adipose tissue and their relationship with the presence of obesity and insulin resistance ...

Introduction: Epigenetic is acquiring great importance in complex diseases, providing mechanisms whereby environmental factors can influence complex diseases such as obesity and type 2 diabetes. Experimental animal and human studies have revealed the association between SCD1 and obesity and insulin resistance. The aim of this study was to evaluate whether metabolic changes after intervention are associated with DNA methylation pattern and if these changes are related to weigh ...

Introduction: Obesity is associated to a pro-inflammatory state with a different pattern of response from the classical response. Also, obesity is associated to non-alcoholic fatty liver disease (NAFLD). In this sense, natural killer T (NKT) cells are a subset of innate immune cells that abundantly reside within the liver and are readily activated by lipid antigens. However, the phenotype and functional characteristics of these cells are no clear in the immune homeostasis in o...

Introduction: HIF-1α, a hypoxia marker, is an important factor for transcriptional regulation of cell metabolism and the adaptation to cellular stress. It modulates the function of phagocytic cells by stimulating surface receptors such as scavenger receptors. But little is known on their relationship in adipose tissue, whose increase has been associated with an increased risk of atherosclerosis. The aim of this study is to analyze in adipose tissue the association between...

Introduction: The stearoyl-CoA desaturase 1 (SCD1) is an enzyme involved in the metabolism of fatty acids, and seems to be involved in the regulation of atherosclerosis development. In this study we want to check the expression of SCD1 in visceral and subcutaneous adipose tissue and its relationship with the metabolic syndrome.Methods: We measured SCD1 mRNA and protein expression in visceral and subcutaneous adipose tissue from 25 morbidly obese patients...
