Is the age of the father associated with placental weight or the ratio of placental weight to birthweight? Placental weight and placental to birthweight ratio increased according to increasing paternal age, also after adjustment for maternal age. High paternal age and also high placental to birthweight ratio have been associated ...

During pregnancy most of women will experience some kind of pain, either as a result of a pre-existing condition (low back pain, headache, fibromyalgia, and rheumatoid arthritis) or as a direct consequence of pregnancy (weight gain, postural changes, pelvic floor dysfunction, hormonal factors). However, chronic pain management during pregnancy and ...

The management of pregnant women with anti-Jsb is challenging due to the paucity of antigen-negative blood for fetal and neonatal transfusion. A 29-year-old woman with anti-Jsb was referred for assessment of recurrent fetal losses. With the presence of the sister as a historically matched donor, she was planned for active ...

The objective was to examine the relationship between ovulatory follicle size and embryo/fetal survival by using circulating concentrations of bovine pregnancy associated glycoproteins (bPAGs) to detect the presence of an embryo/fetus and monitor placental function. Before examining the relationship between bPAGs, ovulatory follicle size and embryo/fetal survival, the half-life of ...

Iodine deficiency during pregnancy and lactation may adversely affect fetal and infant development. Two initiatives were introduced in New Zealand to prevent deficiency: (1) mandatory fortification of bread with iodised salt; and (2) provision of a subsidised iodine supplement (150 μg) for all pregnant and breastfeeding women. The aim of this ...

Background The effects of moderate variations in dietary iodine intake on maternal and fetal thyroid function are poorly understood. Recent studies question the usefulness of neonatal screening of congenital hypothyroidism as a tool for monitoring iodine deficiency. We proposed to test the hypothesis of an association between iodine intake during ...

Maternal obesity during pregnancy has been linked to an increased risk of obesity and cardiometabolic disease in the offspring, a phenomenon attributed to developmental programming. Programming effects may be transmissible across generations through both maternal and paternal inheritance, although the mechanisms remain unclear. Using a mouse model, we explored the ...

Maternal plasma contains circulating cell-free (ccf) DNA fragments originating from both the mother and the placenta. The proportion derived from the placenta is known as the fetal fraction. When measured between 10 and 20 gestational weeks, the average fetal fraction in maternal plasma is 10 to 15%, but can range ...

Human and guinea pig fetuses are completely dependent on an adequate maternal vitamin C (vitC) intake. Shortage of micronutrients can have negative implications for fetal health and pregnancy outcome; however, knowledge of maternal vitC deficiency's impact on fetal development is sparse and reports of pregnancy outcome have been divergent. The ...

The transcription factor STAT5A is essential for two processes during mammary gland development. First, it controls the development of luminal progenitor cells from stem cells(1) and second, it has a role during pregnancy where it is required for alveologenesis(2) (,) (3) the production of clusters of luminal cells that synthesize ...

Maternal blood leptin levels are positively associated with adiposity. Recent studies suggest that leptin is also abundantly produced by the placenta and may function as a regulator of foetal growth. Our goal was to examine mid-pregnancy levels of leptin in maternal blood in relation to birthweight for gestational age (BW/GA) ...

The relationship between maternal intrinsic factors and placental traits was investigated on three Southern Mediterranean breed of sheep; Cukurova Assaf (CA), Cukurova (C) and Cukurova Meat Sheep (CMS). The effect of parity and birth type were also considered in the study as a potential influencing factor. Our hypothesis was to ...

Pregnancy invokes a doubling of intestinal calcium absorption while lactation programs skeletal resorption to provide calcium to milk. Post-weaning bone formation restores the skeleton's bone mineral content (BMC), but the factors that regulate this are not established. We used Pth null mice to test whether parathyroid hormone (PTH) is required ...
