Introduction Studies conducted in the recent past have demonstrated the role of inflammation, obesity and dysfunctional insulin signaling as contributing factors in the pathogenesis of acute coronary syndrome (ACS). However, pharmacological interventions targeting a single pathway have not proven useful in the long run. This indicates that a synergism occurs between the various risk factors and hence calls for a combinatorial approach. This study was planned to study the interplay, if any, between pregnancy associated plasma protein-A (PAPP-A), inflammation and adiposity in patients with ACS...

OBJECTIVE: In patients with pre-gestational and gestational diabetes mellitus (GDM), insulin requirements often increase during the third trimester of pregnancy in order to maintain proper glycemic control. However, a fraction of patients demonstrate a significant decrease in insulin requirements in late gestation. We aimed to evaluate the clinical significance of decreasing insulin requirements in patients with pre-gestational diabetes and GDM with respect to fetal wellbeing and pregnancy outcome...

Diabetes is associated with beta cell mass loss and islet dysfunctions. mTORC1 regulates beta cell survival, proliferation and function in physiological and pathological conditions, such as pregnancy and pancreatectomy. Here we show that deletion of Raptor, which is an essential component of mTORC1, in insulin-expressing cells promotes hypoinsulinemia and glucose intolerance. Raptor-deficient beta cells display reduced glucose responsiveness and exhibit a glucose metabolic profile resembling fetal beta cells...

Recent studies suggested that maternal and placental leptin receptor (LEPR) may be involved in maternal glucose metabolism in pregnancy. To identify maternal and fetal LEPR common variants influencing gestational glycemic traits, we performed association study of 24-28-week maternal fasting glucose, glucose 1 hour after the consumption of a 50-g oral glucose load, fasting insulin and indices of beta-cell function (HOMA-β) and insulin resistance (HOMA-IR) in 1,112 unrelated women and their children. Follow-up of 36 LEPR loci identified 3 maternal loci (rs10889567, rs1137101 and rs3762274) associated with fasting glucose, these 3 fetal loci associated with fasting insulin and HOMA1-IR, as well as these 3 maternal-fetal loci combinations associated with HOMA2-β...

The vasotocin/vasopressin and isotocin/mesotocin/oxytocin family of nonapeptides regulate social behaviors and physiological functions associated with reproductive physiology and osmotic balance. While experimental and correlative studies provide evidence for these nonapeptides as modulators of behavior across all classes of vertebrates, mechanisms for nonapeptide inactivation in regulating these functions have been largely overlooked. Leucyl-cystinyl aminopeptidase (LNPEP) - also known as vasopressinase, oxytocinase, placental leucine aminopeptidase (P-LAP), and insulin-regulated aminopeptidase (IRAP) - is a membrane-bound zinc-dependent metalloexopeptidase enzyme that inactivates vasopressin, oxytocin, and select other cyclic polypeptides...

BACKGROUND: Dyslipidemia during pregnancy increase the risk of pregnancy complications. Lipid profiles has strong genetic determinant and numerous susceptibility loci has been identified. However, very few studies focused on the association of lipid-related loci and maternal serum lipids during pregnancy. We, for the first time, investigated the association of common variants in three MODY genes (HNF1A, HNF4A and HNF1B) with serum lipid concentrations and glucose metabolism related quantitative traits in the second trimester of pregnancy...

The glycemic goals of pregnancy are very narrow to reduce excess risks for numerous maternal and fetal complications. Continuous glucose monitors (CGMs) may help women achieve glucose goals and reduce hypoglycemia. CGM use has been found to be safe and effective in pregnancies associated with diabetes. CGM use can accurately identify glycemic patterns among women with and without diabetes in pregnancy. The data on the effects of CGM use on maternal and fetal outcomes are conflicting. Using CGMs in conjunction with continuous subcutaneous insulin infusion therapy in pregnancies complicated by diabetes may improve outcomes...
