BACKGROUND: Lifestyle interventions are the primary prevention strategy for gestational diabetes (GDM) in obese/overweight women; however, these interventions have shown limited effectiveness. Omega-3 polyunsaturated fatty acids (PUFAs) intake has shown beneficial effects on glucose metabolism, lipid fractions and inflammatory factors in women who already have GDM. Combining PUFAs supplementation with a lifestyle intervention could achieve lower increase of glucose levels by improving insulin sensitivity...

BACKGROUND/OBJECTIVE: Low 25-hydroxyvitamin D levels [25(OH)D] may increase the risk for cardiovascular disease (CVD). In pregnant women excessive weight gain and 25(OH)D deficiency are common complications and both could have deleterious consequences on their children. We aimed to study the relationship between serum 25(OH)D and CVD risk factors in pregnant women and in their offspring at school age. SUBJECTS/METHODS: Fasting serum 25(OH)D and its bioavailable fraction were quantified in 310 healthy pregnant women [with adequate (n = 113), insufficient (n = 113) and excessive (n = 84) weight gain]...

Serial cloning by somatic cell nuclear transfer (SCNT) is a critical tool for the expansion of precious transgenic lines or resetting the lifespan of primary transgenic cells for multiple genetic modifications. We successfully produced second-generation cloned goats using donor neonatal fibroblasts from first-generation clones. However, our attempts to produce any third-generation clones failed. SCNT efficiency decreased progressively with the clonal generations. The rate of pregnancy loss was significantly greater in recloning groups (P<0...

Background: African-American (AA) women have poorer pregnancy outcomes and studies in nonpregnant women suggest a different etiology of weight gain in AA compared with white women. We hypothesized that physiologic factors such as low energy expenditure and physical activity would be present in AA compared with white women in pregnancy. Objective: We aimed to identify physiologic risk factors for disordered energy balance in AA and white women early in pregnancy...

The human (h) placental lactogenic hormone chorionic somatomammotropin (CS) is highly produced during pregnancy and acts as a metabolic adaptor in response to maternal insulin resistance. Maternal obesity can exacerbate this "resistance" and a >75% decrease in CS RNA levels was observed in term placentas from obese versus lean women. The genes coding for hCS (hCS-A and hCS-B) and placental growth hormone (hGH-V) as well as the hCS-L pseudogene and pituitary growth hormone (GH) gene (hGH-N) are located at a single locus on chromosome 17...

We investigated the insulin release induced by glucose, the Ca2+ oscillatory pattern and the cAMP/PKA and PLC/PKC pathways in islets from adult rats that were reared under diets with 17% protein (C) or 6% protein (LP) during gestation, suckling and after weaning and in rats receiving diets with 6% protein during gestation, followed by a 17% protein diet after birth (R). Glucose-induced first-phase insulin secretion was reduced in LP and R islets, and the second phase was partially restored in the R group. Glucose stimulation did not modify [Ca2+]i, but it reduced the [Ca2+] oscillatory frequency in the R group compared to the C group...

Premature rupture of membranes (PROM) is a common pregnancy complication that frequently results in maternal and perinatal morbidity. The present methods for diagnosing PROM do not satisfy clinical requirements. The present study aimed to examine the proteome profile of amniotic fluid (AF) and maternal plasma, screen unique proteins in AF, and evaluate their diagnostic value for diagnosing PROM. The proteome profiles of AF and maternal plasma were examined via liquid chromatography coupled with tandem mass spectrometry‑based proteomic techniques...

OBJECTIVES: Metformin has been reported to reduce the risk of preeclampsia. It is also known to influence soluble fms-like tyrosine kinase-1 (sFlt-1) levels, which correlate significantly with the gestation of onset and severity of preeclampsia. The main aim of this systematic review and meta-analysis was to determine whether metformin use is associated with the incidence of hypertensive disorders of pregnancy (HDP). METHODS: MEDLINE (1947 - September 2017), Scopus (1970 - September 2017) and the Cochrane Library (since inception - September 2017) were searched for relevant citations in English language...

Diabetes is a common chronic condition in women of reproductive age. Preconception care is crucial to reducing the risk of adverse maternal and fetal outcomes, such as hypertensive disorders, abnormal fetal growth, traumatic delivery and stillbirth, associated with poor glycemic control. Insulin is the preferred medication to optimize glucose control in women with pregestational diabetes. Frequent dose adjustments are needed during pregnancy to achieve glycemic goals, and team-based multidisciplinary care may help...

BACKGROUND: The World Health Organization (WHO) adopted more stringent diagnostic criteria for GDM in 2013, to improve pregnancy outcomes. However, there is no global consensus on these new diagnostic criteria, because of limited evidence. The objective of the study was to evaluate maternal characteristics and pregnancy outcomes in two cohorts in the Netherlands applying different diagnostic criteria for GDM i.e. WHO-2013 and WHO-1999. METHODS: A multicenter retrospective study involving singleton GDM pregnancies in two regions, between 2011 and 2016...

Gestational diabetes mellitus (GDM) occurs in 2-9% of all pregnancies. Evidence suggests that the use of insulin in treating hyperglycemia in GDM patients reduces the risk of perinatal morbidity. Pregnancy is an exciting time in a woman's life. However, once patient is diagnosed with GDM, she will be managed more intensively. GDM is managed using diet and exercise but one in six women with GDM requires insulin. A 35-year-old woman at the 14th gestational week of her tenth pregnancy was seen for routine prenatal care...

PURPOSE OF REVIEW: Excess fetal growth is increasingly recognized as a risk factor for childhood obesity, and mounting evidence supports that maternal glucose is not the only driver. This review focuses on the role of clinically applicable maternal non-glycemic contributors to excess fetal growth, particularly lipids, in addition to amino acids (AA), insulin resistance, inflammation, maternal nutrition, and gestational weight gain (GWG) in obesity and gestational diabetes mellitus (GDM)...

Gestational diabetes mellitus is defined as diabetes diagnosed in the second or third trimester of pregnancy in patients with no history of diabetes prior to gestation. It is the most common complication of pregnancy. The underlying pathophysiology shares some common features with type 2 diabetes mellitus combining relatively insufficient insulin secretion with increased peripheral insulin resistance. While a certain degree of insulin resistance is the physiological characteristics of the second half of pregnancy, it is significantly more pronounced in patients with gestational diabetes...
