Abstract
Providing the appropriate quantity and quality of food needed for both the mother's well-being and the healthy development of the offspring is crucial during pregnancy. However, the macro- and micronutrient intake also impacts the body's regulatory supersystems of the mother, such as the immune, endocrine, and nervous systems, which ultimately influence the overall development of the offspring. Of particular importance is the association between unhealthy maternal diet and neurodevelopmental disorders in the offspring. Epidemiological studies have linked neurodevelopmental disorders like autism spectrum disorders, attention-deficit-hyperactivity disorder, and schizophrenia, to maternal immune activation (MIA) during gestation. While the deleterious consequences of diet-induced MIA on offspring neurodevelopment are increasingly revealed, neuroinflammation is emerging as a key underlying mechanism. In this review, we compile the evidence available on how the mother and offspring are both impacted by maternal dietary imbalance. We specifically explore the various inflammatory and anti-inflammatory effects of dietary components and discuss how changes in inflammatory status can prime the offspring brain development toward neurodevelopmental disorders. Lastly, we discuss research evidence on the mechanisms that sustain the relationship between maternal dietary imbalance and offspring brain development, involving altered neuroinflammatory status in the offspring, as well as genetic to cellular programming notably of microglia, and the evidence that the gut microbiome may act as a key mediator.

Abstract
AbstractThere is lack of evidence on the differential impact of maternal macronutrient consumption: carbohydrates (CHO), fats and protein on birth weight. We investigated the association between maternal dietary macronutrient intakes and their sub-components such as saccharides and fatty acids and birth weight. This analyses included 1,196 women with singleton pregnancies who were part of the CAffeine and REproductive health study in Leeds, UK between 2003 and 2006. Women were interviewed in each trimester. Dietary information was collected twice using a 24-h dietary recall about 8–12 weeks and 13–27 weeks of gestation. Multiple linear regression models adjusted for alcohol and smoking in trimester 1, showed that each additional 10 g/d CHO consumption was associated with an increase of 4 g (95 % CI 1, 7;P=0·003) in birth weight. Conversely, an additional 10 g/d fat intake was associated with a lower birth weight of 8 g (95 % CI 0, 16;P=0·04) when we accounted for energy contributing macronutrients in each model, and maternal height, weight, parity, ethnicity, gestational age at delivery and sex of the baby. There was no evidence of an association between protein intake and birth weight. Maternal diet in trimester 2 suggested that higher intakes of glucose (10 g/d) and lactose (1 g/d) were both associated with higher birth weight of 52 g (95 % CI 4, 100;P=0·03) and 5 g (95 % CI 2, 7;P<0·001) respectively. These results show that dietary macronutrient composition during pregnancy is associated with birth weight outcomes. An appropriately balanced intake of dietary CHO and fat during pregnancy could support optimum birth weight.

Abstract
According to the Pedersen hypothesis, fetal hyperinsulinism is the major cause for adverse neonatal outcome. We investigated associations between insulin levels in cord blood and fetal complications. Three groups of 21 insulin-dependent diabetic patients with different insulin levels in cord blood were matched according to White Classes. Insulin levels in cord blood of < 20 microU/ml were considered normal (controls), 20-50 microU/ml intermediate group, and > 50 microU/ml high (cases). The mean (+/-S.D.) insulin level in cord blood in the three groups was 10.7+/-5.6, 28.6+/-8.1, and 104.0+/-61.0 microU/ml, respectively. Controls and cases showed significant differences in birth weight > 90th percentile (9.5% vs. 76.2%), premature birth < 37 weeks (4.8% vs. 71.4%), caesarean delivery (28.6% vs. 66.4%), hypoglycaemia of the neonate (14.3% vs. 61.9%), cushingoid appearance (4.8% vs. 42.9%) and respiratory distress syndrome (0% vs. 33.3%). The results of the intermediate group were between the controls and the cases. Insulin levels in cord blood > 20 microU/ml represent a continuum of increasing diabetogenic fetopathy. We consider neonates with insulin levels in cord blood < 20 microU/ml as metabolically healthy, those with 20-50 microU/ml as having mild fetopathy, and those with > 50 microU/ml as having marked fetopathy, respectively.

Abstract
Nutrient delivery via the fetal gastrointestinal tract may be a potential prenatal treatment for intrauterine growth retardation. Uptake from continuous intraamniotic infusions with nutrient incorporation into developing fetal tissues has not previously been shown. To study this, ovarian-end fetuses of 18 time-mated rabbit does underwent amniotic cavity catheterization and either esophageal ligation (EL) or sham operation (SH) on gestational day 23 (term, 33 days). Saline plus 14C D-glucose and 3H proline were infused into the amniotic fluid for 4 days. Nutrients absorbed by the EL fetus represent only those taken up into the maternal circulation and subsequently redelivered hematogenously to the fetus. Radioactivity of fetal blood and organs was determined using a liquid scintillation counter. All infused does and 10 of 18 infused fetuses (56%) survived the entire study period. In SH fetuses, uptake of 14C per mg of tissue was highest in the lung and significantly greater in the stomach, jejunum, ileum, and lung than in fetal blood (P less than .05). Uptake of 3H per mg of tissue was also highest in the lung and significantly greater than fetal blood in the stomach, small intestine, lung, and liver (P less than .05). Each organ's 14C and 3H uptake was greater in SH than in EL fetuses (P less than .001).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The growth and development of the placenta is critical to fetal growth and development; however, little is known regarding the mechanisms controlling placental growth and development. Human placental membranes are known to possess receptors for insulin-like growth factors I and II (IGF-I and IGF-II) from early gestation, and increasing evidence supports a major role for IGF-I and/or IGF-II in fetal growth and development. Therefore, the IGFs may also play a significant role in regulating placental growth and development. We report here that an adult human liver IGF-II cDNA hybridizes to poly(A)+ RNAs of human placentas from different gestational ages. There are four placental poly(A)+ RNA species that hybridize to IGF-II cDNA, the major one of which is about 6000 bases. The sizes of the hybridized transcripts are the same for placentas of different gestational ages. Furthermore, the IGF-II sequences expressed in the human placenta were quantitated by dot blot hybridization. The second trimester placenta expresses more IGF-II mRNA sequences than placenta of first trimester and term. Interestingly, the term placentas from diabetic pregnancies also express more of these sequences than those from normal pregnancies. These results suggest that there are developmental changes in the expression of the IGF-II gene in the placenta and that IGF-II may promote placental growth by way of an autocrine and/or paracrine mechanism. Moreover, fetuses developing in diabetic pregnancies receive a large influx of glucose, which in turn may stimulate the expression of IGF-II sequences in placenta, resulting in higher utilization of glucose and overgrowth of placenta. This may explain the macrosomia and high incidence of malformations and stillbirths known to result from pregnancies in diabetics.

Abstract
Rapid growth of human fetal tissues requires insulin or insulin-like growth factors. A high rate of human fetal growth occurs between implantation and about 14 weeks of gestation. Fetal pancreatic insulin secretion begins much later. Since maternal insulin does not cross the blood/placental barrier, other sources of insulin or insulin-like growth factors may be provided for fetal development. We report here that placental polyadenylylated RNAs from the first and third trimester of normal pregnancy as well as from term pregnancies of diabetic mothers hybridize to a 32P-labeled cloned cDNA of an insulin-related sequence expressed in fetal pancreas. Moreover, placentas from diabetic women express much more of these sequences. These results suggest that insulin-related genes are expressed in placental tissue during fetal development and may be a source of growth-promoting hormones for the human fetus. Fetuses developing in diabetic women receive a large influx of glucose. This in turn may stimulate the expression of insulin-related sequences, which may result in higher utilization of glucose, thus bringing about the macrosomia and high incidence of malformation and still-births known to result from pregnancies in diabetics.

Abstract
Poorly controlled diabetic pregnancies are associated with hyperglycemia and elevated ketones. While glucose is known to cross the placenta, there is limited information regarding the placental transfer of ketones and their associated cardiovascular and metabolic effects in the fetus. Thus, the present study was undertaken to evaluate the transfer of the ketoacid beta hydroxybutyrate across the ovine placenta and to determine the effects of this ketoacid on maternal and fetal physiologic and metabolic parameters. Pregnant ewes (110 to 120 days' gestation) were instrumented with catheters in the lateral branch of both uterine arteries, uterine veins, femoral artery, and femoral vein, and electromagnetic flow probes were placed on both middle uterine arteries. Catheters were placed in the fetal carotid artery and jugular vein, and a catheter and balloon were placed in the amniotic fluid. Beta hydroxybutyrate (0.39 mmole/100 ml of uterine blood flow) and antipyrine (00.27 mmole/100 ml of uterine blood flow) as a second reference marker, were infused simultaneously into the uterine arteries for a period of 2 hours. The beta hydroxybutyrate concentrations in the uterine vein increased to 5.93 +/- 1.32 mmoles/L, and were associated with a significant increase in maternal heart rate and a slight but significant reduction in uterine blood flow. No changes in maternal arterial blood gas values were noted. The concentration of beta hydroxybutyrate in the fetal carotid arteries increased from 0.01 +/- 0.01 mmole/l to 0.15 +/- 0.03 mmole/L, and were associated with a significant reduction in fetal PaO2 (24.2 +/- 0.9 to 17.9 +/- 1.9 mm Hg) and an elevation of fetal lactate levels (1.86 +/- 0.17 to 5.07 +/- 1.56 mmoles/L).

Abstract
Previous studies from our laboratory have shown that beta hydroxybutyrate crosses the ovine placenta in small amounts during maternal hyperketonemia and produces significant reductions in fetal PaO2 and increased fetal lactate levels. The present study evaluates the effects of fetal hyperketonemia on fetal and maternal cardiovascular and biochemical parameters. Pregnant ewes (110 to 120 days' gestation) were instrumented with catheters in the femoral artery, femoral vein, and uterine veins, and electromagnetic flow probes were placed on the middle uterine arteries. The fetal carotid artery and jugular vein were catheterized, and a catheter and balloon were placed in the amniotic fluid. Beta hydroxybutyrate (0.44 mmole/min) and antipyrine (0.03 mmole/min) were simultaneously infused directly into the fetal jugular vein for 90 minutes. The fetal beta hydroxybutyrate level increased from a baseline of 0.12 +/- 0.08 to 6.80 +/- 0.46 mmoles/L and was associated with a significant decrease in fetal PaO2 (23.7 +/- 2.4 to 16.0 +/- 0.4 mm Hg) and a large increase in the fetal lactate (1.85 +/- 0.27 to 5.43 +/- 0.92 mmoles/L) at 90 minutes. The present results suggest that during fetal hyperketonemia fetal oxygenation is significantly reduced and may contribute to the increased perinatal mortality in the pregnant diabetic patient.

Abstract
A high incidence (over 20%) of obesity was found in 250 neonates living in a rural area of Tunisia, by using weight and ponderal index per gestational age as the nutritional index. Maternal diabetes was probably excluded. Two surveys on nutritional habits--one on the general population and the other on pregnant women--showed a tendency to consume a high carbohydrate and low protein diet. The effect of a badly balanced maternal diet on the fetus is discussed.

Abstract
Early in development, the fetal pancreas is characterized by the presence of two distinct generations of endocrine cells and a B-Cell mass that is unresponsive to acute changes in circulating glucose levels. Near the end of intrauterine development, the normal pancreas has "matured" and contains a single generation of endocrine cells and B-Cells that are responsive to changes in glucose concentrations. Recent microscopic examination of resected pancreatic tissue from an infant with hyperinsulinemic hypoglycermia revealed a combination of all three of the currently accepted findings in this neonatal condition: hyperplasia, adenomatosis, and nesidioblastosis. These observations prompted the following hypothesis: When compared to the usual histology of the developing pancreas, nesidioblastosis may be interpreted as an abnormal continuation of normal proliferation of endocrine cells; hyperplasia may be a specific overproduction of the Secondary Islands of Langerhans; and adenomatosis may be an abnormal continuation or overgrowth of the Primary Island of Langerhans. Such extrapolation suggests that infants with hyperinsulinemic hypoglycemia may represent a failure in the normal histological and functional maturation of the endocrine portion of the fetal pancreas.

Abstract
The effect of oral beta-sympathomimetic tocolytic therapy on neonatal serum glucose concentrations in the first several hours after delivery was examined in 12 babies. Hypoglycemia was noted in eight babies, and was sustained over at least a 30-minute period in five. The group with sustained hypoglycemia had a higher cord serum insulin concentration, a lower serum glucose nadir, and a more rapid initial rate of serum glucose disappearance than those babies with normoglycemia or transient hypoglycemia. Sustained hypoglycemia was observed in five of six babies delivered within two days of the termination of tocolytic therapy, but was not present in any of six babies delivered five or more days after the end of tocolytic therapy. Speculations as to the interaction between beta-sympathomimetic tocolytic drugs administered to the mother and fetal and neonatal glucose metabolism are made.
