Objective: Fetal growth restriction is associated with increased postnatal cardiovascular morbidity. The alterations in heart physiology and structure caused by in utero nutrient deprivation have not been extensively studied. We aim to investigate the impact of maternal food restriction on the cardiac proteome of newborn rats with normal (non-fetal growth-restricted (FGR)) and reduced (FGR) birth weight. Methods: On day 14 of gestation, 10 timed pregnant rats were randomized into two nutritional groups: (a) Standard laboratory diet and (b) 50% global food restriction. Pups born to food-restricted mothers were subdivided, based on birthweight, into fetal growth-restricted (FGR) and non-FGR, while pups born from normally nourished mothers were considered controls. Rat neonates were euthanized immediately after birth and the hearts of 11 randomly selected male offspring (n = 4 FGR, n = 4 non-FGR, n = 3 control group) were analyzed using quantitative proteomics. Results: In total, 7422 proteins were quantified (q < 0.05). Of these, 1175 were differentially expressed in FGR and 231 in non-FGR offspring vs. control with 151 common differentially expressed proteins (DEPs) between the two groups. Bioinformatics analysis of DEPs in FGR vs. control showed decreased integrin and apelin cardiac fibroblast signaling, decreased muscle contraction and glycolysis, and over-representation of a protein network related to embryonic development, and cell death and survival. Conclusion: Our study illustrates the distinct proteomic profile of FGR and non-FGR offspring of food-restricted dams underlying the importance of both prenatal adversities and birth weight in cardiac physiology and development.

The diabetic syndrome affects pregnancy, contributing to placental functional and structural disruptions and impaired fetal development, with many reports indicating tobacco-associated morbidity and perinatal mortality. In our study, an experimental rat model of diabetes and cigarette smoke exposure in pregnant rats was used to determine the impact of the combination of diabetes and exposure to cigarette smoke during pregnancy on maternal oxidative stress biomarkers and placental and fetal development. Diabetes was induced by streptozotocin, and dams were exposed to cigarette smoke by mainstream smoke generated by a mechanical smoking device and delivered into a chamber. Four groups of dams were studied: nondiabetic (C, control) and diabetic (D) exposed to filtered air and nondiabetic (CS) and diabetic (DS) exposed to cigarette smoke prior to and during pregnancy. Maternal oxidative stress biomarkers, placental morphology, and fetal growth were determined close to term. The combination of diabetes and cigarette smoke resulted in elevated maternal blood glucose levels and increased number of small fetuses. Placentas from the DS group showed increased junctional zone and decreased labyrinthine area. The morphological alterations were characterized by extensive vascular congestion, thickness, and hyalinization of the vascular walls, numerous decidual cells with abundant glycogen, and macrophages with cytoplasmic inclusions of hemosiderin. Additionally, they showed increased glycogen accumulation and junctional zone structural derangement with ectopic giant cells. No alterations were observed in maternal oxidative stress status. Thus, our result suggests that diabetes makes pregnant rats more susceptible to the adverse effects of exposure to cigarette smoke on placental morphometry and fetal growth.

The aim of this study was to evaluate the influence of ligature-induced periodontal disease in pregnant rats on their newborn's health parameters. Twenty-four female adult Wistar rats were divided into two groups: the control group (G1) and the group that was submitted to dental ligatures around second upper molars (G2). After the four week period of development of periodontitis, the female animals were mated with male adult Wistar rats. There were no differences in the body weight of females between the two groups during mating and pregnancy. No differences were observed among the groups in relation to the viable newborn index. However, there were differences in newborn birth weight, explained by the diverse size of the litters. In this study, ligature-induced periodontal disease did not promote changes during pregnancy that resulted in low birth weight in newborn Wistar rats.

AbstractThe placenta is the principal organ regulating respiratory, nutritional, endocrine and metabolic functions on behalf of the developing fetus. Changes in gene expression patterns of placenta-specific genes may influence fetal growth. We profiled the expression of 17 genes related to placenta functioning in term placentas (n=677) to identify genes differentially expressed across birth weight categories [small (SGA), appropriate (AGA) and large (LGA) for gestational age].

Arginine (a non-essential amino acid) and its conversion to nitric oxide (NO) can promote formation of new blood vessels and cause vasodilation. This may reduce resistance and increase blood flow to the uterus and placenta, and the delivery of nutrients for fetal growth and survival. In pregnant rats, dietary arginine deficiency causes IUGR and increases fetal death and perinatal mortality, whereas dietary arginine supplementation reverses this. Human IUGR is associated with impaired NO synthesis, and eNOS activity in umbilical vein endothelial cells, but maternal arginine supplements have produced inconclusive results. We hypothesised that maternal arginine supplementation (MAS) in the pig (a species with naturally occurring IUGR), during late gestation, when placental angiogenesis and vascularity increase, would increase birth and placental weights. Large White (LW) and Landrace (LR) gilts (n = 285) and sows (n = 326), were fed either a control or arginine supplemented (+25 g/d arginine, Nutreco Progenos premix) diet (2.5 kg/d) in late gestation (d75-term at ~114 days). Number born, born alive, still born and mummified, birth weight and d10 weight of progeny were measured. Data were analysed using Univariate ANOVA. MAS in late gestation in gilts and sows reduced the number of still born (Con: 1.17 ± 0.13 piglets/litter; Arg: 0.84 ± 0.09 piglets/litter; P = 0.046). In LW gilts, MAS increased birth weight (Con: 1.21 ± 0.05kg; Arg: 1.34 ± 0.05kg; P < 0.05), and litter birth weight (Con: 13.38 ± 0.72 kg; Arg: 15.27 ± 0.73 kg; P < 0.05). MAS also increased birth weight in LW (Con: 1.17 ± 0.06 kg; Arg: 1.30 ± 0.06 kg; P < 0.05) and LR (Con: 1.47 ± 0.05 kg; Arg: 1.60 ± 0.05 kg; P < 0.05) sows, and reduced still borns in LW sows (Con: 1.12 ± 0.14 piglets/litter; Arg: 0.77 ± 0.09 piglets/litter; P < 0.05). MAS in late gestation improves pregnancy outcomes in terms of piglet survival and birth weight, in LW and LR gilts and sows. MAS during critical periods of placental development may enhance placental-fetal blood flow and nutrient transfer, thereby improving fetal growth and survival.

A total of 48 Katahdin x Pelibuey multiparous ewes were used to evaluate the e ect of nutritional restriction (40 %) before (30 d, RT), after (50 d, TR) or both periods (80 d, RR) compared with a control group on maternal body status, early fetal growth and lamb birth weights. Only twin bearing ewes were selected at d 50 of pregnancy for fetal measurements by ultrasonography and record of birth weight. Compared with control ewes, lower (p < 0.05) weight and body condition score had RT and RR ewes at mating time, likewise, TR and RR ewes at d 50 post-conception. There were mainly di erences between fetuses from control and RT ewes, being higher (p < 0.05) the vesicular, abdominal and fetal area, as well as crown-rump length and birth weight for RT fetuses. In conclusion, preconception undernutrition positively altered the early fetal growth and lamb birth weights in hair ewes pregnant with twins.

Objective To evaluate the accuracy of 35-37 weeks‘ ultrasound for fetal growth restriction (FGR) detection and the impact of 30th-33rd weeks vs 35th-37th weeks ultrasound on perinatal outcomes. Design A prospective randomized trial Setting Tertiary referral hospital in Portugal. Population Low risk pregnant women Methods We enrolled 1061 women: 513 in the control group (ultrasound at 30th-33rd weeks) and 548 in the study group (with an additional ultrasound at 35th-37th weeks). FGR was defined as an estimated fetal weight (EFW) below 10th percentile. We calculated the overall accuracy of the 35-37 weeks’ ultrasound and compared perinatal outcomes between both groups. Main outcome measure Detection of late FGR Results The ultrasound at 35-37 weeks had an overall accuracy of FGR screening of 94%. Spearman’s correlation coefficient between EFW and birthweight centile was higher for at 35-37 weeks’ ultrasound (ρ = 0.75) compared with 30-33 weeks’ ultrasound (ρ = 0.44). The study group had a lower rate of operative vaginal deliveries (24.4% vs 39.3%, p = 0.005) and cesarean deliveries for nonreassuring fetal status (16.8% vs 38.8%, p < 0.001). For FGR prediction, the area under the receiver-operating characteristics curve of EFW centile at 35-37 weeks’ ultrasound was 0.90 (95% CI, 0.86-0.95). Conclusions A later ultrasound (35-37 weeks) had a higher correlation between EFW and birthweight centiles and was associated with a lower rate of cesarean and operative deliveries for nonreassuring fetal status compared to an earlier ultrasound, which reinforces that antenatal identification of FGR allows close monitoring and appropriate management.

The purpose of the study is to evaluate the effect of placental dysfunction caused by gestational endotheliopathy on the course of labor and the condition of the newborn. The first group consisted of 70 patients with placental dysfunction with gestational endotheliopathy confirmed by laboratory-instrumental findings in the first trimester of pregnancy. The control group included 30 pregnant women with physiological gestational course. PD secondary to GE leads to preterm birth, fetal distress, increases the percentage of caesarean section, contributes to the delay of fetal growth and birth weight, poor infant status and perinatal complications.

The study was conducted to investigate the effects of caffeine treatment during organogenesis period to the fetal birth weight, using rat (Rattus norvegicus) as the animal model. Thirty-six primipararat obtained from Unit Pengembangan Hewan Percobaan, Gadjah Mada University (UPHP-GMU), 3 month old, 165-200 g body weight, were divided into 6 groups, consisted of 6 rats each. Six of the ratshave been selected based on the estrous cycles, and only rat with regular estrous were use for theexperiment. The rat then were mated, and during day 6-14 of the pregnancies were treated orally withcaffeine diluted in aquadest in dosage: placebo (1 cc aquadest) for group I (control), and 5.4, 10.8, 16.2,21.6, and 27 g/200 g body weight/day for treatment groups II-VI respectively. The pregnant rat bodyweights were determined at day 6 of pregnancies for calculating the caffeine treatment dosages. At day 20thof the pregnancies all of the pregnant rats were caesarotomized, and all of the fetuses were removed and weighed. The results showed that all of the treatment groups have significantly lower birth weightcompare to the groups control group. More over, fetal obtained from the treatment groups also showedserious subcutaneous hemorrhagic.Keywords: organogenesis, Rattus norvegicus, birth weight

Background: Lithium is an effective treatment in pregnancy and postpartum for the prevention of relapse in bipolar disorder, but there is a lack of knowledge about the potential adverse impact on fetal development. Aims: To investigate the impact of lithium exposure on early fetal growth. Methods: In this retrospective observational cohort study, we included all singleton pregnancies of women using lithium and referred for advanced fetal ultrasound scanning between 1994 and 2018 to the University Medical Centers in Leiden and Rotterdam, the Netherlands ( n=119). The Generation R study, a population-based cohort, served as a non-exposed control population from the same geographic region ( n=8184). Fetal head circumference, abdominal circumference, femur length, and transcerebellar diameter were measured by ultrasound at 18–22 weeks of gestation. Results: Lithium use during pregnancy was associated with an average increase in head circumference of 1.77 mm (95% confidence interval: 0.53, 3.01), in abdominal circumference of 5.54 mm (95% confidence interval: 3.95, 7.12) and in femur length of 0.59 mm (95% confidence interval: 0.22, 0.96) at 18–22 weeks gestation. Furthermore, lithium use during pregnancy was associated with an average increase in birth weight of 142.43 grams (95% confidence interval: 58.01, 226.89), whereas it was associated with an average decrease of 1.41 weeks in gestational duration (95% confidence interval: −1.78, −1.05). Conclusions: Lithium use during pregnancy was associated with increased fetal growth parameters at 18–22 weeks gestational age and increased birth weight. Further research is needed to evaluate both short- and long-term implications, as well as the mechanisms driving this difference in growth.

Pregnancy-induced hypertension (PIH), especially preeclampsia, is a major cause of maternal and perinatal morbidity and mortality worldwide. The impact of PIH on birth outcomes has not been extensively studied. PIH has been confirmed to increase significantly the risk of low birth weight by both increasing preterm birth as well as reducing fetal growth. Low birth weight or IUGR babies have been associated with the occurrence of several chronic diseases in later life. However, to date, there have been few studies on the effects of PIH on infant growth and neonatal wellbeing. The purpose of this study was to evaluate the fetal growth and wellbeing of newborns born of mothers with confirmed pregnancy induced hypertension.Material and methods: This was prospective opservational study during the period of the last year, 1st of July 2018 up to the end of June 2019 conducted at the University Clinic for Gynecology and Obstetrics in Skopje. As pregnancy induced hypertension is defined the condition of blood pressure equal to or greater than 130/90 mmHg on more than two occasions greater than six hours apart without proteinuria after 21 weeks of gestation. All other more severe conditions are defined as pre-eclampsia or eclampsia. As outcome was considered the birth weight, gestational age and white blood cells count. IUGR was defined as birth weight below the tenth percentile of expected weight for gestational age. Also maternal age and BMI were considered as conjoined risk factor for the birth weight. Results: In this study, 4726 newborns were born at the University Clinic for Gynecology and Obstetrics, and for analysis were considered 4273 newborns who were late preterm (35 and 36 gestational weeks) or term newborns. Two groups were evaluated: control group of 200 consecutively born newborns (late preterm and term) of healthy mothers and 100 newborns (late preterm and term) consecutively born of mothers with confirmed diagnosis of PIH, which constituted the study group. Within the control group, the proportion of Small for Gestational Age-SGA was 6,3%, and in the group of mothers with PIH was 9,5% (p<0,05). The maternal mean age of the hypertensive mothers was (32.8±5.0) years while that of normotensive mothers was (26.6±3.7) years, and there was not statistical significance (p>0.05). The Body Mass Index was higher in hypertensive mothers, compared to the healthy mothers (31,3±2.02 vs. 27.8±2.8). The mean gestational age of the study group was (35.8±1.8) weeks compared to that in control group (37.4±1.2) weeks. The number of White Blood Cells (WBC) count in newborns of hypertensive mothers was 21.4±5.3x109/L compared with the control group, 18.5±3.12x109/L (p=0.005). Neonatal thrombocytopenia was found in 32% of neonates of preeclamptic mothers while it's found only in 9.5% of neonates in control group p<0,002. Discussion: The limitation of this study was the lack of data about maternal smoking, life style, etc. There is limited number of studies examining the correlation between fetal growth and PIH, and every information is of great value. The fact is that this condition can progress in more severe degree of hypertension and deleterious effects on the mother itself and on her child, if not treated on time. Conclusion: A change in infant growth of the IUGR baby itself (e.g. catch-up growth) such as in the critical early infant period may also have long-term effects on health later in life, and this change of postpartum growth may be influenced by PIH. Therefore, it is important to study postpartum infant growth patterns of babies born to mothers with PIH, and to determine if there are differences in infant growth between babies with and those without IUGR. And, the most important action is to monitor and treat pregnancy induced hypertension and prevent more severe condition of pre-eclampsia.
