Summary: Studies have shown that exposure to low and high temperatures during pregnancy has negative effects on fetal development. The placenta, which plays a crucial role in fetal development, may also be affected by suboptimal temperatures. However, it is unclear whether the placenta mediates the association between suboptimal temperature and birth weight.

Summary: This study found a positive correlation between maternal urinary cotinine concentration and placental weight and the ratio of placental weight to birth weight. After reaching a certain concentration, placental weight decreased in male offspring while it plateaued in female offspring. Active smoking during pregnancy significantly increased both placental weight and placental weight to birth weight ratio.

Summary: Preterm birth is a global epidemic and factors such as maternal nutrition and placental-infant TL influence the risk of PTB. Maternal nutrition affects PTB risk through its influence on maternal TL. PTB also independently affects TL regulation in offspring. However, the strength of these associations and the influence of other factors remain unclear. Whether maternal TL is simply a biomarker of maternal nutrition status and PTB risk or a causative factor of PTB is yet to be determined.

Summary: Limited evidence exists on the effects of maternal dietary patterns on birth weight, and most studies conducted so far did not adjust their findings for gestational age and sex, leading to potentially biased conclusions. In this study, a novel method was applied to derive dietary patterns among pregnant women and evaluate the associations with birth weight for gestational age. The findings suggest that adherence to an unhealthy dietary pattern is associated with an increased likelihood of having a large for gestational age newborn.

Summary: Adverse environmental factors in early life can lead to metabolic programming and increased risk of adult diseases. Studies on placental transporters in relation to idiopathic birth weight alterations and maternal obesity are limited. Our study highlights the importance of placental programming in birth weight and neonatal metabolic outcomes.

Summary: Inadequate maternal nutrition before and during pregnancy is a significant risk factor for poor fetal development. This study shows that an integrated maternal nutrition intervention can reduce the risk of low birth weight by 66.99% and increase average birth weight by 219 grams.

Summary: Placental development plays a crucial role in the progression of pregnancy, and exposure to environmental toxicants, including metals, can have an impact on placenta and subsequently affect pregnancy outcomes. This study investigates the correlation between placental levels of 14 essential and non-essential elements and neonatal weight. The findings suggest that certain metal concentrations in the placenta may influence fetal growth, with cobalt and strontium associated with higher newborn weight, while lithium, molybdenum, and selenium associated with lower newborn weight.

Summary: This systematic review examines the impact of carbohydrate intake during pregnancy on newborn birth weight. Although some studies indicate a relationship between maternal carbohydrate intake and neonatal birth weight, there are contradictory findings. Future studies should consider the type and amount of carbohydrates consumed.

Summary: This study investigated the potential effects of metronidazole on pregnancy outcomes and found that it can cause hepatotoxicity in pregnant rats, reduce the number of implanted embryos and fetal viability, increase fetal lethality and resorptions, and affect fetal development and placental pathology.

Summary: Birth weight is important for piglet survival, and there is ongoing interest in understanding the impact of nutrition during gestation on birth weight. This paper reviews previous attempts to increase birth weight and proposes targeting specific windows of gestation for nutritional manipulations. The mean birth weight needs to be increased by at least 50-100 g to improve survival rates for piglets with a birth weight below 1 kg. However, it is unlikely that the mean birth weight can be increased by more than 100 g based on existing studies. Nutritional manipulations during the middle of gestation or during the embryonic phase may be more effective.

Summary: The study explores the relationship between maternal weight, leptin receptor expression in maternal peripheral blood mononuclear cells (PBMC), and placental tissue to analyze its impact on birth outcomes. The results suggest that maternal nutrition status can affect fetal development and birth outcomes through leptin receptor expression.

Summary: This study found an association between FT4 and birth weight as well as birth weight discordance in twins, while TSH was not associated with birth weight. These findings have implications for obstetricians in preventing birth weight discordance in twin pregnancies.

Summary: Exposure to cadmium during pregnancy has harmful effects on fetal and placental development, as well as maternal health. It also increases the risk of diseases in offspring during infancy, adolescence, and adulthood. The mechanisms behind cadmium-induced teratogenicity and disease development are still largely unknown, but epigenetic changes in DNA, RNA, and protein have been observed. This review aims to provide a comprehensive overview of these epigenetic alterations induced by prenatal cadmium exposure and their long-term effects.

Summary: This study found that mercury exposure is associated with preeclampsia and adverse birth outcomes. Pregnant women with higher levels of mercury in their blood are more likely to develop mild and severe preeclampsia, as well as have low birth weight and preterm birth.
