Abstract
BACKGROUND Increased uptake of essential fatty acids during pregnancy through seafood and supplementation has been shown to positively correlate with gestational age and increased infant birth weight. We aimed to evaluate the effect of maternal dietary intake of essential fatty acids, supplementation on gestational period and infant birth weight. MATERIALS A literature search with the help of various databases such as PubMed, Google Scholar, Web of Science and Scopus was conducted. METHODS Original research articles and intervention-based studies, which involve an association between dietary intake and supplementation of essential fatty acids during full-term pregnancy on human infant birth outcomes and published from 2011 to 2021, were included. RESULTS In total, there were 21 intervention-based studies, including full-term pregnant women with or without existing comorbidities, which compared essential fatty acids in the form of dietary sources and supplementation with dietary counseling and with or without placebo. The intervention trials included in this review were conducted in developed and developing countries. Half of the pregnant women who enrolled in the study had comorbidities such as diabetes and hypertension, which might increase their risk of adverse maternal and infant birth outcomes. Most of the studies included in the review have reported a positive association between improvised dietary and supplementation intake of essential fatty acids with increased length of gestation, infant birth weight and other parameters such as head circumference, infant birth length and growth velocity. CONCLUSION Positive correlations were found between increased consumption of essential fatty acids in food sources and supplements with improvised infant birth weight and gestational period.

Abstract
Background: Pregnancy is a vulnerable period for the mother and the infant and exposures to environmental chemicals in utero can influence neonatal morbidity and mortality. There is a momentum toward understanding and exploring the current maternal biological mechanisms specific to in utero effects, to improve birth outcomes. This study aims to examine the current understanding of the role of biomarkers that may be associated with term of pregnancy, infant birth weights and infant development in utero.Methods: Electronic searches were conducted in PubMed, Embase, OvidMD, and Scopus databases; and all relevant research articles in English were retrieved. Studies were selected if they evaluated maternal blood plasma/serum biomarkers proposed to influence adverse birth outcomes in the neonate. Data were extracted on characteristics, quality, and odds ratios from each study and meta-analysis was conducted.Results: A total of 54 studies (35 for meta-analysis), including 43,702 women, 50 plasma markers and six descriptors of birth outcomes were included in the present study. The random effect point estimates for risk of adverse birth outcomes were 1.61(95%CI: 1.39-1.85, p < 0.0001) for inflammation-related biomarkers and 1.65(95%CI: 1.22-2.25, p = 0.0013) for growth factor/hormone-related biomarkers. All subgroups of plasma markers showed significant associations with adverse birth outcomes with no apparent study bias.Conclusions: The two subsets of plasma markers identified in this study (inflammation-related and growth factor/hormone-related) may serve as potentially valuable tools in the investigation of maternal molecular mechanisms, especially select pathways underlying inflammatory and immunological mediation in terms of modulating adverse infant outcomes. Future large, prospective cohort studies are needed to validate the promising plasma biomarkers, and to examine other maternal biological matrices such as cervicovaginal fluid and urine.

Abstract
OBJECTIVE To evaluate the effect of frozen, compared with fresh, embryo transfer on neonatal and pediatric weight and weight gain trajectory. DESIGN Retrospective cohort study. SETTING Academic medical center. PATIENT(S) Women who underwent fresh or frozen embryo transfer at the Mayo Clinic from 2010 to 2014. All included embryo transfers resulted in a singleton live birth. Children were followed from birth to at least 18 months. When possible, growth was evaluated to 5 years of age. INTERVENTIONS(S) Fresh versus frozen embryo transfer. MAIN OUTCOME MEASURE(S) Propensity score methodology was used to balance the two groups by maternal characteristics and gestational age before evaluating outcomes. Each infant and childhood growth measurement was compared between the two groups. RESULT(S) Of the 136 women, 87 underwent a fresh embryo transfer and 49 underwent a frozen embryo transfer. Birth length and head circumference were significantly different in infants delivered after fresh versus frozen embryo transfer. There was a statistically significant difference in birth weight between infants born after fresh versus frozen embryo transfer. However, this difference did not persist when adjusted for gestational age, sex, and maternal factors. Childhood growth measurements including age- and sex-specific weight, and body mass index percentiles were not significantly different between groups. CONCLUSION(S) This study confirmed an association of frozen embryo transfer and increased birth weight, but the association did not persist when controlling for confounding maternal factors. We found no effect of fresh versus frozen embryo transfer on neonatal weight and childhood weight gain trajectory.

Abstract
Background: There is paucity of information on mechanisms constituting adverse birth outcomes. We assessed here the relationship between vascular integrity and adverse birth effects. Methods and results: Third trimester maternal plasma (n = 144) from the Maternal-Infant Research on Environmental Chemicals Study (MIREC) was analysed for vascular, inflammatory and oxidative stress markers by HPLC-fluorescence, protein array and EIA method. Analysis of the <25th and >75th percentile birth weight subgroups revealed markers associated with birth weight (ETs, MMP-9, VEGF, and 8-isoPGF-2α) and gestational age (ET-1, MMP-2, and VEGF). Conclusions: Mechanistic insights into adverse birth outcome pathways can be achieved by integrating information on multiple biomarkers, physiology using systems biology approach.
