The Effect of Maternal Obesity on Breast Milk Fatty Acids and Its Association with Infant Growth and Cognition-The PREOBE Follow-Up.

This study analyzed how maternal obesity affected fatty acids (FAs) in breast milk and their association with infant growth and cognition to raise awareness about the programming effect of maternal health and to promote a healthy prenatal weight. Mother-child pairs ( = 78) were grouped per maternal pre-pregnancy body mass index (BMI): normal-weight (BMI = 18.5-24.

The Impact of Maternal Pre-Pregnancy Body Weight and Gestational Diabetes on Markers of Folate Metabolism in the Placenta.

Dietary methyl donors, including folate, may modify the placenta and size at birth but the influence of maternal body weight has not been widely investigated. We therefore examined whether maternal or fetal folate status, together with indices of placental folate transport, were modulated by either maternal pre-pregnancy body mass index (BMI i.e.

Maternal BMI and gestational diabetes alter placental lipid transporters and fatty acid composition.

Introduction: Placental fatty acid (FA) uptake and metabolism depend on maternal supply which may be altered when women have a high pre-pregnancy body mass index (BMI) or develop gestational diabetes (GDM). Consequently, an impaired FA transport to the fetus may negatively affect fetal development. While placental adaptation of maternal-fetal glucose transfer in mild GDM has been described, knowledge on placental FA acid metabolism and possible adaptations in response to maternal obesity or GDM is lacking.

Maternal Pre-Pregnancy Obesity Is Associated with Altered Placental Transcriptome.

Maternal obesity has a major impact on pregnancy outcomes. There is growing evidence that maternal obesity has a negative influence on placental development and function, thereby adversely influencing offspring programming and health outcomes. However, the molecular mechanisms underlying these processes are poorly understood.

Maternal PPARG Pro12Ala polymorphism is associated with infant's neurodevelopmental outcomes at 18 months of age.

Background: Peroxisome proliferator activated receptors (PPARs) are ligand activated transcription factors with crucial functions in lipid homeostasis, glucose metabolism, anti-inflammatory processes, placental development, and are involved in cognitive functions and neurodegenerative diseases. Polymorphisms in PPAR genes are shown to influence the activity of these receptors.

Aims: 1) To examine the association of PPARG Pro12Ala polymorphism in pregnant women and their offspring on infant's neurodevelopmental outcomes during the first 18 months of life; 2) to determine the influence of Pro12Ala polymorphism on fatty acid concentrations in plasma phospholipids and placental tissue.

Effects of obesity and gestational diabetes mellitus on placental phospholipids.

Gestational diabetes mellitus (GDM) is associated with adverse effects in the offspring. The composition of placental glycerophospholipids (GPL) is known to be altered in GDM and might reflect an aberrant fatty acid transfer across the placenta and thus affect the foetal body composition. The aim of this study was to investigate possible effects of obesity and GDM, respectively, on placental GPL species composition.

Microbiota from the distal guts of lean and obese adolescents exhibit partial functional redundancy besides clear differences in community structure.

Recent research has disclosed a tight connection between obesity, metabolic gut microbial activities and host health. Obtaining a complete understanding of this relationship remains a major goal. Here, we conducted a comparative metagenomic and metaproteomic investigation of gut microbial communities in faecal samples taken from an obese and a lean adolescent.
