Leptin is now considered an important signalling molecule of the reproductive system, as it regulates the production of gonadotrophins, the blastocyst formation and implantation, the normal placentation, as well as the foeto-placental communication. Leptin is a peptide hormone secreted mainly by adipose tissue, and the placenta is the second leptin-producing tissue in humans. Placental leptin is an important cytokine which regulates placental functions in an autocrine or paracrine manner. Leptin seems to play a crucial role during the first stages of pregnancy as it modulates critical processes such as proliferation, protein synthesis, invasion and apoptosis in placental cells...

BACKGROUND: Vitamin D deficiency in pregnancy has important maternal and fetal implications, with increased risk of developing gestational diabetes, preeclampsia, preterm birth and small for gestational age birthweight. It is recommended that every pregnant woman should take 5 μg (200 IU) of vitamin D per day during pregnancy and lactation. AIMS: This study aimed to determine the prevalence of women taking vitamin D supplementation and to identify the reasons for patients not taking supplementation within women attending an antenatal clinic in Dublin...

Background: Polycystic ovary syndrome (PCOS) puts patients at higher risk for obesity and diabetes. Poor health literacy is also associated with these conditions. Notably, weight loss is associated with improved ovulation and pregnancy rates for women with PCOS. In this study the association between health literacy and body mass index (BMI) among women with PCOS was examined. Methods: The health literacy of women with PCOS was measured using the Arabic version of the single item literacy screener (SILS) at a university medical center...

The contribution of environmental factors to pancreatic islet damage in type 1 diabetes remains poorly understood. In this study, we crossed mice susceptible to type 1 diabetes, where parental male (CD8(+) T cells specific for IGRP206-214; NOD8.3) and female (NOD/ShiLt) mice were randomized to a diet either low or high in AGE content and maintained on this diet throughout pregnancy and lactation. After weaning, NOD8.3(+) female offspring were identified and maintained on the same parental feeding regimen for until day 28 of life...

Gestational diabetes mellitus (GDM) characterizes by foetoplacental endothelial dysfunction. Human umbilical vein endothelial cells (HUVECs) from women with GDM show increased L-arginine transport via the human cationic amino acid transporter 1 (hCAT-1). Moreover, expression of endothelial nitric oxide synthase (eNOS) and nitric oxide synthesis are increased. Exosomes are increased in maternal plasma from GDM. We evaluated the role of foetoplacental endothelial exosomes on endothelial dysfunction in GDM. Exosomes were isolated from HUVECs from normal (ExN) and GDM (ExGDM) pregnancies...

To achieve optimal development of a newborn, breastfeeding is extensively recommended, but little is known about the role of non-nutritive bioactive milk components. We aimed to characterize the fatty acid esters of hydroxy fatty acids (FAHFAs), namely palmitic acid hydroxystearic acids (PAHSAs)-endogenous lipids with anti-inflammatory and anti-diabetic properties, in human breast milk. Breast milk samples from 30 lean (BMI=19-23) and 23 obese (BMI>30) women were collected 72h postpartum. Adipose tissue and milk samples were harvested from C57BL/6J mice...

Dyslipidaemia occurs in pregnancy to secure foetal development. The mother shows a physiological increase in plasma total cholesterol and triglycerides (TG) as pregnancy progresses (i.e. maternal physiological dyslipidaemia in pregnancy). However, in some women pregnancy-associated dyslipidaemia exceeds this physiological adaptation. The consequences of this condition on the developing foetus include endothelial dysfunction of the foetoplacental vasculature and development of foetal aortic atherosclerosis. Gestational diabetes mellitus (GDM) associates with abnormal function of the foetoplacental vasculature due to foetal hyperglycaemia and hyperinsulinaemia, and associates with development of cardiovascular disease in adulthood...

The obesity epidemic in the United States and other countries has contributed to an increase in the rates of gestational diabetes and hypertension. In the past, it was thought that most cases of gestational diabetes and hypertension would resolve after completion of pregnancy. In this issue of the Journal, Pace et al. (Am J Epidemiol. 2017;186(10):1115-1124) clearly documented that both gestational diabetes and hypertension lead to diabetes and hypertension and that the combination of both during pregnancy leads to very high rates of subsequent diabetes and hypertension...

BACKGROUND: Global prevalence of overweight/obesity and gestational diabetes (GDM) is increasing. In pregnant women both conditions affect offspring's later health. Overweight/obesity is a risk factor of GDM; to what extent maternal overweight/obesity explains long-term effects of GDM in offspring is unknown. OBJECTIVE: To evaluate effects of maternal pre-pregnancy overweight/obesity (BMI ⩾25 kg/m(2)) and GDM, occurring together or separately, on body composition among adult offspring...

The gut microbiota contributes to the regulation of glucose metabolism in pregnancy. Abundance of the genus Collinsella is positively correlated with circulating insulin; however, it is unclear what determines Collinsella abundance. This study aims to validate the correlation between Collinsella and insulin and to elucidate if macronutrient intake alters Collinsella abundance and gut microbiota composition. Gut microbiota profiles were assessed by 16S rRNA sequencing in 57 overweight and 73 obese pregnant women from the SPRING (Study of PRobiotics IN Gestational diabetes) trial at 16 weeks gestation and correlated with metabolic hormone levels and macronutrient intake...

BACKGROUND: The worldwide burden of stillbirths is large, with an estimated 2.6 million babies stillborn in 2015 including 1.3 million dying during labour. The Every Newborn Action Plan set a stillbirth target of ≤12 per 1000 in all countries by 2030. Planning tools will be essential as countries set policy and plan investment to scale up interventions to meet this target. This paper summarises the approach taken for modelling the impact of scaling-up health interventions on stillbirths in the Lives Saved tool (LiST), and potential future refinements...

Diabetes mellitus in pregnancy has been known to affect the embryonic development of various systems, including cardiovascular and nervous systems. However, whether this disease could have a negative impact on embryonic respiratory system remains controversial. In this study, we demonstrated that pregestational diabetes mellitus (PGDM)-induced defects in lung development in mice are mainly characterized by the changes in the morphological structure of the lung. Immunostaining and Western blotting showed that proliferation increased and apoptosis decreased in PGDM...

Background: Chronic insulin resistance (IR) is a basic part of the pathophysiology of gestational diabetes mellitus. Nutrition significantly impacts IR and weight loss reduces insulin levels, whereas weight gain increases the concentrations. Therefore, we surveyed the effect of nutrition intervention on IR in pregnant women and whether this effect is irrespective of weight gaining in accordance with Institute of Medicine limits. Methods: This prospective, randomized clinical trial was carried out among 150 primiparous pregnant mothers in fifteen health centers, five hospitals, and 15 private obstetrical offices in Isfahan...
