    The association of candidate genes and psychological symptoms of depression, anxiety, and stress among women with gestational diabetes mellitus (GDM) in Malaysia was determined in this study, followed by the determination of their odds of getting psychological symptoms, adjusted for socio-demographical background, maternal, and clinical characteristics. Single nucleotide polymorphisms (SNPs) recorded a significant association between SNP of EPHX2 (rs17466684) and depression symptoms (AOR = 7.854, 95% CI = 1.330-46.360) and stress symptoms (AOR = 7.664, 95% CI = 1.579-37.197). Associations were also observed between stress symptoms and SNP of OXTR (rs53576) and (AOR = 2.981, 95% CI = 1.058-8.402) and SNP of NRG1 (rs2919375) (AOR = 9.894, 95% CI = 1.159-84.427). The SNP of EPHX2 (rs17466684) gene polymorphism is associated with depression symptoms among Malaysian women with GDM. SNP of EPHX2 (rs17466684), OXTR (rs53576) and NRG1 (rs2919375) are also associated with stress symptoms.

    AIM: To determine the relationships between maternal and fetal outcomes and gestational diabetes mellitus (GDM), impaired fasting glucose (IFG) and impaired glucose tolerance (IGT), respectively.
    METHODS: A retrospective cohort study design was used with 149 patients with abnormal oral glucose tolerance test (OGTT) and 149 normal patients. Statistical analysis used was the chi-squared test, Fisher's exact test or the Student's t-test, as appropriate. P < 0.05 was considered significant.
    RESULTS: The level of hyperglycemia according to the OGTT (World Health Organization criteria) was associated with pre-eclampsia, polyhydramnios and macrosomia in GDM patients. There was no increase in the complications of preterm labor and premature rupture of membranes, despite the increased risk of polyhydramnios. Although treated with insulin, macrosomia still occurred in patients with GDM, but there was no shoulder dystocia as there was an increase in the incidence of cesarean section (CS). The IGT group was not associated with adverse fetal or maternal outcomes, but there was an increase in intervention and the incidence of CS. The IFG group was associated with a significantly increased risk of pre-eclampsia and macrosomia. These findings challenge the concept of IFG being a lesser pathology than GDM. Further prospective studies with a larger number of patients are needed to ascertain the significance of these findings.
    CONCLUSION: There was an increased risk of pre-eclampsia and macrosomia in both the GDM and IFG patients, but IGT was not associated with adverse fetal or maternal outcomes.

    Background Fibroblast growth factors (FGFs); FGF-21 and FGF-23, have been proposed to be associated with metabolic syndrome. However, data on the role of these peptides in gestational diabetes mellitus (GDM) are limited. Therefore, this study was designed to assess the association of serum FGF-21 and FGF-23 with the risk of GDM. Furthermore, we evaluated the circulation of these peptides in pregnancy and post-puerperium. Materials and methods Fifty-three pregnant subjects with GDM and 43 normal glucose tolerance (NGT) pregnant women participated in this study. Serum FGF-21 and FGF-23 were measured during pregnancy and post-puerperium. Results FGF-21 and FGF-23 were low in GDM compared to NGT during pregnancy. There were no significant differences in the level of these peptides post-puerperium. Using logistic regression, FGF-23 [odds ratio (OR) 0.70 (95% confidence interval [CI]: 0.50-0.96)] was inversely associated with GDM, so a 1-μg/mL decrease in FGF-23 levels was associated with a 1.4-fold increased risk of developing GDM and this remained statistically significant after adjustment for confounders [adjusted OR (aOR) 0.70 (95% CI: 0.50-0.98)]. There was no association of FGF-21 with the development of GDM risk. Conclusions Lower FGF-23 concentrations could be involved in the pathophysiology of GDM. FGF-21, even though associated with metabolic risk factors in pregnancy, may not be a fundamental factor in GDM.

    AIMS/INTRODUCTION: The association between gestational diabetes mellitus (GDM) and adverse maternal and perinatal outcomes in twin pregnancies remains unclear. This study was undertaken to highlight risk factors for GDM in women with dichorionic (DC) twins, and to determine the association between GDM DC twins and adverse maternal and perinatal outcomes in a large homogeneous Taiwanese population.

    MATERIALS AND METHODS: A retrospective cross-sectional study was carried out on 645 women with DC twins, excluding pregnancies complicated by one or both fetuses with demise (n = 22) or congenital anomalies (n = 9), who gave birth after 28 complete gestational weeks between 1 January 2001 and 31 December 2018. Univariable and multiple logistic regression analyses were carried out.

    RESULTS: Maternal age >34 years (adjusted odds ratio 2.52; 95% confidence interval 1.25-5.07) and pre-pregnancy body mass index >24.9 kg/m2 (adjusted odds ratio 2.83, 95% confidence interval 1.47-5.46) were independent risk factors for GDM in women with DC twins. Newborns from women with GDM DC twins were more likely to be admitted to the neonatal intensive care unit (adjusted odds ratio 1.70, 95% confidence interval 1.06-2.72) than newborns from women with non-GDM DC twins. Other pregnancy and neonatal outcomes were similar between the two groups.

    CONCLUSIONS: Advanced maternal age and pre-pregnancy overweight or obesity are risk factors for GDM in women with DC twins. Except for a nearly twofold increased risk of neonatal intensive care unit admission of newborns, the pregnancy and neonatal outcomes for women with GDM DC twins are similar to those for women with non-GDM DC twins.

    BACKGROUND: Adipocytokines participate in regulating the inflammatory response in glucose homeostasis and type 2 diabetes. However, among these peptides, the role of adipocyte-specific fatty-acid-binding protein (AFABP), chemerin, and secreted protein acidic and rich in cysteine (SPARC) in gestational diabetes (GDM) has not been fully investigated.

    METHOD: The maternal fasting level of adipocytokines of 53 subjects with GDM and 43 normal pregnant (NGDM) was measured using multiplex immunoassay at 24-28 weeks, before delivery, immediate postpartum, and 2-6 months postpuerperium.

    RESULTS: Higher levels of AFABP were associated with a 3.7-fold higher risk of GDM. Low chemerin levels were associated with a 3.6-fold higher risk of GDM. Interleukin-10 (IL-10) was inversely associated with the risk of GDM. SPARC had no association with GDM. AFABP was directly correlated to interleukin-6 (r = 0.50), insulin resistance index (r = 0.26), and body mass index (r = 0.28) and inversely correlated to C-reactive protein (r = -0.27). Chemerin levels were directly and strongly correlated with IL-10 (r = 0.41) and interleukin-4 (r = 0.50) and inversely correlated to insulin resistance index (r = -0.23) in GDM but not NGDM. In the longitudinal assessment, there were no significant differences in AFABP and chemerin concentrations of both studied groups.

    CONCLUSION: AFABP and chemerin were associated with a higher risk of GDM. These adipocytokines were related to insulin resistance, body mass index, and inflammation in pregnant women diagnosed with GDM.

    BACKGROUND: There is clinical and experimental evidence for altered adenosine signalling in the fetoplacental circulation in pregnancies complicated by diabetes, leading to adenosine accumulation in the placenta. However, the consequence for fetoplacental vasocontractility is unclear. This study examined contractility to adenosine of chorionic vessels from type 1 diabetes mellitus, gestational diabetes mellitus and normal pregnancies.

    METHODS: Chorionic arteries and veins were isolated from human placenta from normal, gestational diabetes mellitus and type 1 diabetes mellitus pregnancies. Isometric tension recording measured responses to adenosine and the thromboxane A2 analogue U46619 (thromboxane A2 mediates fetoplacental vasoconstriction to adenosine). Adenosine and thromboxane prostanoid receptor protein expression was determined by immunoblotting.

    RESULTS: Adenosine elicited contractions in chorionic arteries and veins which were impaired in both gestational diabetes mellitus and type 1 diabetes mellitus. Contractions to potassium chloride were unchanged. Adenosine A2A and A2B receptor protein levels were not different in gestational diabetes mellitus and normal pregnancies. Contractions to U46619 were unaltered in gestational diabetes mellitus arteries and increased in type 1 diabetes mellitus arteries. Overnight storage of vessels restored contractility to adenosine in gestational diabetes mellitus arteries and normalized contraction to U46619 in type 1 diabetes mellitus arteries.

    CONCLUSION: These data are consistent with the concept of aberrant adenosine signalling in diabetes; they show for the first time that this involves impaired adenosine contractility of the fetoplacental vasculature.
