Abstract
OBJECTIVE To determine levels of galectins (gal)-1 and -3 (implicated in angiogenesis/immunologic mechanisms) in intrauterine growth restricted (IUGR), large (LGA) and appropriate for gestational age (AGA) pregnancies, as these groups differ in fat mass, angiogenic patterns and immune responses. METHODS Cord-blood (UC) gal-1 and -3 concentrations were measured in 30 IUGR, 30 LGA and 20 AGA singleton full-term infants and their mothers (MS). RESULTS IUGR, LGA and AGA groups did not differ in gal-1 and -3 concentrations. UC gal-1 levels were lower when mothers were older [b=-0.651, CI 95% -1.186 (-0.116), P=0.018] and UC gal-3 levels were increased when mothers presented gestational diabetes [b=9.836, CI 95% 3.833- (15.839), P=0.002]. In IUGRs MS gal-3 and in LGAs UC gal-1 were decreased in multiparas [b=-5.372, CI 95% -9.584- (-1.161), P=0.014], and [b=-7.540, CI 95% -14.606- (-0.473), P=0.037], respectively. No correlations were found between MS or UC gal-1 and gal-3 concentrations. CONCLUSIONS Lower UC gal-1 levels, when mothers were older, and increased UC gal-3 levels in cases of gestational diabetes, possibly reflect angiogenic activity. In multiparas, decreased MS gal-3 and UC gal-1 levels in IUGR/LGA, respectively, might imply inflammatory response against immunosuppression expected in subsequent pregnancies, as compared to the first one.

Abstract
The potential benefits and risks of physical exercise on fetal development during pregnancy remain unclear. The aim was to analyze maternal oxidative stress status and the placental morphometry to relate to intrauterine growth restriction (IUGR) from diabetic female rats submitted to swimming program after embryonic implantation. Pregnant Wistar rats were distributed into 4 groups (11 animals/group): control-nondiabetic sedentary rats, control exercised-nondiabetic exercised rats, diabetic-diabetic sedentary rats, and diabetic exercised-diabetic exercised rats. A swimming program was used as an exercise model. At the end of pregnancy, the maternal oxidative stress status, placental morphology, and fetal weight were analyzed. The swimming program was not efficient to reduce the hyperglycemia-induced oxidative stress. This fact impaired placental development, resulting in altered blood flow and energy reserves, which contributed to a deficient exchange of nutrients and oxygen for the fetal development, leading to IUGR.

Abstract
OBJECTIVE To define the contribution of maternal variables which influence the measured level of maternal serum placental growth factor (PlGF) in screening for pregnancy complications. METHODS Maternal characteristics and medical history were recorded and serum levels of PlGF were measured in women with a singleton pregnancy attending for three routine hospital visits at 11 + 0 to 13 + 6, 19 + 0 to 24 + 6 and 30 + 0 to 34 + 6 or 35 + 0 to 37 + 6 weeks' gestation. For women delivering phenotypically normal live births or stillbirths ≥ 24 weeks' gestation, variables from maternal demographic characteristics and medical history important in the prediction of PlGF were determined from a linear mixed-effects multiple regression. RESULTS Serum levels of PlGF were measured in 38,002 cases in the first trimester, 10,281 in the second trimester and 12,392 in the third trimester. Significant independent contributions to serum PlGF were provided by gestational age, maternal age, weight and racial origin, cigarette smoking, diabetes mellitus, and gestational age at delivery and birth-weight Z-score of the neonate in the previous pregnancy. The machine used to measure serum PlGF was also found to have a significant effect. Allowing for other factors, the effect of maternal age on PlGF changed over the three trimesters, whereas other variables had constant effects over the three trimesters. Random-effects multiple regression analysis was used to define the contribution of maternal variables that influence the measured serum PlGF and express the values as multiples of the median (MoMs). The model was shown to provide an adequate fit of MoM values for all covariates, both in pregnancies that developed pre-eclampsia and in those without this complication. CONCLUSIONS A model was fitted to express the measured level of maternal serum PlGF across the three trimesters of pregnancy as MoMs, after adjusting for variables of maternal characteristics and medical history that affect this measurement.

Abstract
BACKGROUND While infections are a major cause of neonatal mortality in India even in full-term neonates, this is an especial problem in the large proportion (~20%) of neonates born underweight (or small-for-gestational-age; SGA). One potential contributory factor for this susceptibility is the possibility that immune system maturation may be affected along with intrauterine growth retardation. METHODS In order to examine the possibility that differences in immune status may underlie the susceptibility of SGA neonates to infections, we enumerated the frequencies and concentrations of 22 leukocyte subset populations as well as IgM and IgA levels in umbilical cord blood from full-term SGA neonates and compared them with values from normal-weight (or appropriate-for-gestational-age; AGA) full-term neonates. We eliminated most SGA-associated risk factors in the exclusion criteria so as to ensure that AGA-SGA differences, if any, would be more likely to be associated with the underweight status itself. RESULTS An analysis of 502 such samples, including 50 from SGA neonates, showed that SGA neonates have significantly fewer plasmacytoid dendritic cells (pDCs), a higher myeloid DC (mDC) to pDC ratio, more natural killer (NK) cells, and higher IgM levels in cord blood in comparison with AGA neonates. Other differences were also observed such as tendencies to lower CD4:CD8 ratios and greater prominence of inflammatory monocytes, mDCs and neutrophils, but while some of them had substantial differences, they did not quite reach the standard level of statistical significance. CONCLUSIONS These differences in cellular lineages of the immune system possibly reflect stress responses in utero associated with growth restriction. Increased susceptibility to infections may thus be linked to complex immune system dysregulation rather than simply retarded immune system maturation.

Abstract
BACKGROUND Egypt has one of the highest incidences of IUGR. The current study investigates the effect of heavy metals toxicity as risk factors of IUGR and determines the possible role of increased apoptosis in their pathogenesis. METHODS This study was conducted in Assiut, Egypt, included 60 women diagnosed to have IUGR. We measured lead and cadmium levels in blood besides arsenic and cadmium levels in urine. Neonatal scalp hair sample were analyzed for arsenic content. Quantitative determination of human placental Bcl-2 and caspase-3 were performed. RESULTS There are significantly higher levels of heavy metals and caspase-3 and lower levels of placental Bcl-2 in the IUGR group. The levels of heavy metals were positively correlated with caspase-3 while negatively correlated (except cadmium) with Bcl-2 levels. CONCLUSIONS There is an alarming high level of heavy metals toxicity in Egypt that was positively correlated to IUGR. Increased placental apoptosis may be one of the possible mechanisms behind the effect.

Abstract
OBJECTIVE Small for gestational age (SGA) newborns constitute still a major cause of perinatal morbidity and mortality. Overt thyroid disease is a known cause of preterm birth and low birthweight but in its untreated condition it is rare today. In this study, we investigated the possible relation between maternal thyroid function assessed in euthyroid women at each trimester and the incidence of term born SGA neonates. DESIGN A prospective cohort study was performed. PATIENTS Thyroid function was assessed at 12, 24 and 36 weeks gestation in 1051 healthy Caucasian women who delivered at ≥ 37 weeks gestation. MEASUREMENTS One-way anova was used to compare mean TSH and FT4 levels between women with SGA neonates and controls. Multiple logistic regression analysis was performed to adjust for known risk factors of SGA. RESULTS Seventy (6·7%) SGA neonates were identified and they were significantly more often born to women with a TSH ≥ 97·5th at first and third trimester. Multiple logistic regression analysis showed that smoking (OR: 4·4, 95% CI: 2·49-7·64), pre-eclampsia (OR: 2·8, 95% CI: 1·19-6·78) and TSH ≥ 97·5th percentile (OR 3·3, 95% CI 1·39-7·53) were significantly related to SGA. Maternal FT4 levels and TPO-Ab status were not associated with SGA offspring. CONCLUSIONS Our data show that TSH levels in the upper range of the reference interval at different trimesters (3·0-3·29 mIU/l) are independently related to an increased risk of delivering SGA neonates at term.

Abstract
Placental insufficiency is associated with fetal hypoglycemia, hypoxemia, and elevated plasma norepinephrine (NE) that become increasingly pronounced throughout the third trimester and contribute to intrauterine growth restriction (IUGR). This study evaluated the effect of fetal adrenal demedullation (AD) on growth and pancreatic endocrine cell mass. Placental insufficiency-induced IUGR was created by exposing pregnant ewes to elevated ambient temperatures during mid-gestation. Treatment groups consisted of control and IUGR fetuses with either surgical sham or AD at 98 days gestational age (dGA; term = 147 dGA), a time-point that precedes IUGR. Samples were collected at 134 dGA. IUGR-sham fetuses were hypoxemic, hypoglycemic, and hypoinsulinemic, and values were similar in IUGR-AD fetuses. Plasma NE concentrations were ~5-fold greater in IUGR-sham compared to control-sham, control-AD, and IUGR-AD fetuses. IUGR-sham and IUGR-AD fetuses weighed less than controls. Compared to IUGR-sham fetuses, IUGR-AD fetuses weighed more and asymmetrical organ growth was absent. Pancreatic β-cell mass and α-cell mass were lower in both IUGR-sham and IUGR-AD fetuses compared to controls, however, pancreatic endocrine cell mass relative to fetal mass was lower in IUGR-AD fetuses. These findings indicate that NE, independently of hypoxemia, hypoglycemia and hypoinsulinemia, influence growth and asymmetry of growth but not pancreatic endocrine cell mass in IUGR fetuses.

Abstract
A case of a residual intrauterine fetal growth is described in a primiparous woman, aged 33 years, undergoing the 37th week of pregnancy. The patient was admitted to the outpatient department of the present clinic complaining of decreased fetal movement in the past few days. The cardiotocography (CTG) was non reactive, with reduced variability for a period of more than 30 minutes. The evaluation of the activity of microparticles (MPs) showed a value of 48.90 nM, which was 21.26 times higher than the mean of normal women of comparable pregnancy age (2.31 ± 1.95 nM) and 18.11 times higher than that of the average women who had intrauterine growth retardation (2.70 ± 2.63 nM). The reasons for this increase in the activity of the MPs are discussed in this case report.

Abstract
The syndrome of delayed fetal growth (SDFG) is one of the most wide-spread pathological conditions while course of pregnancy; it is characterized by disorder of the feto-placental system function. Its incidence is from 3 to 8%. The studying of peculiarities of the system and local immune disorders, coinciding with SDFG, would permit to establish the immune mechanisms of its formation. Revealing of immunoregulation disorders on systemic and local levels would promote the creation of a concept, depicting participation of the immune system in formation of asymmetrical and symmetrical forms of SDFG, to elaborate new approaches for prognosis and diagnosis.

Abstract
AIM To analyze the role of maternal placental growth factor (PlGF) in the prediction of small for gestational age (SGA) birth weight in pregnancy complicated by type 1 diabetes mellitus (T1DM). METHODS A prospective observational study on 59 normotensive T1DM pregnant women, assessing maternal PlGF concentrations between the 10th-14th and 22nd-25th weeks of gestation. RESULTS Number of SGA vs. non-SGA newborns was 11 (18.6%) vs. 48 (81.4%), respectively. First trimester PlGF serum concentrations (pg/mL) were similar between SGA vs. non-SGA groups [data given as median (interquartile range)]: 65.5 (35.58-159.20) vs. 68.23 (11.59-150.03), respectively; P=0.44. A trend for lower PlGF concentrations was observed in the second trimester in the SGA vs. non-SGA group: 63.34 (12.79-119.16) vs. 116.75 (33.93-235.82); P=0.07. In the SGA group, PlGF concentrations did not differ between the first and the second trimester: 65.5 (35.58-159.20) vs. 63.34 (12.79-119.16), respectively; P=0.36. In the non-SGA group, PlGF concentrations were significantly higher at the gestational age of 22-25 weeks compared to 10-14 weeks [116.75 (33.93-235.82) vs. 68.23 (11.59-150.03); P=0.03). CONCLUSIONS Decreased PlGF serum concentration in mid-pregnancy, as well as a lack of physiological increase in PlGF levels between early and mid-gestation, may precede development of SGA in women with T1DM.

Abstract
PURPOSE The aim of the present study was to compare maternal serum and cord blood irisin levels in females whose pregnancies were or were not complicated by idiopathic foetal growth restriction. METHODS A total of 30 subjects participated. The study group consisted of 15 female patients who were referred to our perinatology clinic for delivery because of foetal growth restriction developing in the third trimester. Fifteen females with uncomplicated singleton pregnancies constituted the control group. Irisin levels were assessed in maternal serum, as well as in serum from the umbilical vein and artery. RESULTS The demographic features of the two groups were similar (p > 0.05). Gestational age at delivery and birth weight were higher in females with uncomplicated pregnancies (p = 0.001). Umbilical artery irisin levels were significantly lower in pregnancies complicated by foetal growth restriction compared to controls (p = 0.003). Umbilical artery irisin levels were positively correlated with foetal weight (p = 0.01) and foetal abdominal circumference (measured by ultrasonography) (p = 0.01). Maternal and umbilical vein irisin levels did not differ between the two groups (p > 0.05). CONCLUSIONS The data suggest that umbilical artery irisin levels were lower in pregnancies complicated by foetal growth restriction. Such lower irisin levels may contribute to the pathogenesis of this common condition, and metabolic syndrome may be a long-term consequence of idiopathic FGR.

Abstract
CONTEXT There are increasing concerns that a disrupted endocrine environment may disturb the growth of the fetus. Assisted reproductive technology (ART) situates gamete/embryo in a supraphysiological estradiol (E2) environment and, thus, provides an ideal model to investigate this problem. OBJECTIVE Our objective was to investigate whether the maternal high-E2 environment in the first trimester increases the risks of low birth weight (LBW) and small-for-gestational-age (SGA) birth. METHODS In total, 8869 singletons born after fresh embryo transfer (ET) (n = 2610), frozen ET (n = 1039), and natural conception (NC) (n = 5220) and their mothers were included. Birth weight, LBW, SGA, and maternal serum E2 levels were investigated. RESULTS The mean serum E2 levels of women undergoing fresh ET at 4 and 8 weeks of gestation were significantly higher than those of the women undergoing frozen ET and the women with NC (P < .01). Serum E2 levels of women undergoing fresh ET at 4 and 8 weeks of gestation were positively correlated to those on the day of human chorionic gonadotropin (hCG) administration (r = 0.5 and r = 0.4, respectively; P < 0.01). The birth weight after fresh ET was significantly lower than that after frozen ET and NC (P < 0.01), with increased incidence of LBW and SGA (P < .05). Furthermore, in the fresh ET group, singletons of mothers with high E2 levels (≥10460 pmol/L on the day of hCG administration) had higher risks of LBW (P < .01) and SGA (P < .01) than those with low E2 levels, and maternal serum E2 level on the day of hCG administration negatively correlated with the birth weight (P < .01). CONCLUSIONS The maternal high-E2 environment in the first trimester is correlated with increased risks of LBW and SGA. Evaluation of serum E2 before ET should be adopted to reduce the possibility of high E2 exposure to gamete/embryo.

Abstract
OBJECTIVES To compare the value of Doppler surveillance with maternal blood angiogenic factors at diagnosis for the prediction of adverse outcome in late-pregnancy small-for-gestational-age (SGA) fetuses. METHODS In a cohort of 198 SGA fetuses we evaluated the association of Doppler indices (mean uterine artery pulsatility index (UtA-PI) and cerebroplacental ratio (CPR)) and angiogenic factors (maternal serum levels of soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF)) with the development of pre-eclampsia and adverse perinatal outcome (operative delivery for non-reassuring fetal status or neonatal metabolic acidosis). RESULTS In SGA fetuses subsequently developing pre-eclampsia, mean UtA-PI (P < 0.001), sFlt-1 MoM (P < 0.001) and sFlt-1/PlGF MoM ratio (P < 0.001) were higher, while PlGF MoM was lower (P = 0.004). In SGA fetuses with adverse perinatal outcome, CPR (P < 0.002) and PlGF MoM (P < 0.001) were lower, and sFlt-1/PlGF MoM ratio was higher (P = 0.001). For predicting pre-eclampsia, the areas under the receiver-operating characteristics (ROC) curves for mean UtA-PI, sFlt-1 MoM and the combination of both were 0.852, 0.839 and 0.860, respectively. For adverse perinatal outcome, the areas under the ROC curves for CPR, PlGF MoM and the combination of both were 0.652, 0.656 and 0.684, respectively. The combination of Doppler indices and angiogenic factors did not significantly improve prediction of either pre-eclampsia (P = 0.851) or adverse outcome (P = 0.579). CONCLUSIONS In SGA fetuses, angiogenic factors at diagnosis and follow-up with Doppler ultrasound both predict adverse outcome with a similar performance.

Abstract
OBJECTIVE This experimental study aimed to prospectively investigate the impact of combinations of prenatal and postnatal food manipulations on the metabolic profile of adult offspring. DESIGN On day 12 of gestation, 67 timed pregnant rats were randomized into three nutritional groups, control: standard laboratory food; starved: 50% food restricted, FR; fat-fed: fat-rich diet, FF. Seven hundred and seventy-four (774) pups were born on day 21 and culled to 8 (4 males, 4 females) per litter to normalize rearing. Rats born to starved mothers were later subdivided, based on birthweight (BiW), into fetal growth restricted (FGR) and non-FGR. The pups were then weaned to the diet of their fostered mother until one year old. Thus, 12 groups were studied: 1. CONTROL/CONTROL 14 rats, 2. CONTROL/FR 12 rats, 3. CONTROL/FF 15 rats, 4. FGR/CONTROL 16 rats, 5. FGR/FR 10 rats, 6. FGR/FF 15 rats, 7. non- FGR/CONTROL 10 rats, 8. non- FGR/FR 17 rats, 9. non- FGR/FF 10 rats, 10. FF/CONTROL 15 rats, 11. FF/FR 14 rats, and 12. FF/FF 13 rats. During sacrifice, body weight (BW) and liver weight (LW) were measured (expressed in grams) and concentrations of serum glucose, triglycerides, HDL and NEFA were determined. RESULTS Postnatal food restriction, compared to control diet significantly reduced BW (p=0.004, p=0.036, p<0.001, p=0.008) and LW (p<0.001) in all study groups. Postnatal control diet significantly increased BW in non-FGR compared to FGR rats (p=0.027). No significant differences were detected in biochemical parameters (excluding NEFA) between FGR and non-FGR, regardless of the postnatal diet. CONCLUSIONS Interaction between prenatal and postnatal nutrition produces distinct metabolic profiles. Apart from BiW, prenatal diet had an important impact on the metabolic profile of the adult offspring, implying that intrauterine events should be considered in the estimation of the metabolic risk of an individual, independently of BiW.

Abstract
Monochorionic diamniotic (MD) twins with selective intrauterine growth restriction (sIUGR) have known associations with cardiac complications. However, the cardiac load of dichorionic diamniotic (DD) twins with sIUGR (DD-sIUGR) remains unclear. N-terminal pro-brain natriuretic peptide (NT-pro BNP) is a convenient marker of cardiac dysfunction in neonates, and is elevated in MD twins with sIUGR (MD-sIUGR). However, there are no reports assessing serum NT-pro BNP levels in DD-sIUGR. Here, we aimed to clarify serum NT-pro BNP levels at birth in DD-sIUGR, and to compare them with those of MD-sIUGR. Forty-one DD twin pairs admitted to our center between October 2007 and January 2013 were enrolled in this study and separated into two groups: nine twins with sIUGR (DD-sIUGR group) and 32 twins without sIUGR (DD without sIUGR group). Sixteen MD twins with sIUGR (MD-sIUGR group) served as positive controls. Serum NT-pro BNP levels at birth in DD-sIUGR [median 2,115 pg/ml (range, 443-6,590 pg/ml)] were significantly higher than in DD without sIUGR [1,080 pg/ml (range, 313-3,470 pg/ml); p=0.001], and significantly lower than in MD twins with sIUGR [4,520 pg/ml (range, 529-62,400 pg/ml); p=0.04]. Serum NT-pro BNP levels between larger and smaller DD co-twins were significantly correlated (r = 0.582; p<0.0001). In conclusion, serum NT-pro BNP levels at birth in DD twins with sIUGR were higher than those without, and lower than in MD twins with sIUGR.

Abstract
The aim of this study was to compare decorin (DCN) levels between pregnancies complicated by idiopathic fetal growth restriction (FGR) and uncomplicated pregnancies and to determine the relationship between DCN levels and clinical parameters. The study population consisted of two groups: control group consisted of 13 women with uncomplicated singleton pregnancies in the third trimester. Study group consisted of 14 singleton pregnancies complicated by idiopathic FGR who were admitted to the hospital for delivery in the third trimester of pregnancy. Maternal and fetal DCN levels were measured. Color Doppler flow assessments were performed. Relationship between DCN levels and clinical parameters was determined. Maternal DCN serum levels were significantly higher in complicated pregnancies by idiopathic FGR (p = 0.01). A statistically significant negative correlation was observed between maternal DCN serum levels and neonatal birth weight (r = -0.0506; p = 0.007). There was a significant correlation between umbilical artery (UA) DCN levels and UA S/D ratio (r = 0.512; p = 0.006) and UA RI (r = 0.405; p = 0.036). The risk of high DCN maternal serum levels (>7986.6 pg/mL) in pregnancy complicated by FGR was 8.25 times higher (RR = 8.25; 95% CI, 1.4-46.8). The results of our study showed that the presence of increased DCN levels in women with FGR could contribute to pathogenesis of the disease.

Abstract
OBJECTIVE To explore the long-term impact of intrauterine growth restriction (IUGR) among a diverse, contemporary cohort of U.S. children. DESIGN AND METHODS A retrospective cohort of 42 children exposed to IUGR and 464 unexposed who were members of Kaiser Permanente of Colorado. Height and weight measurements since birth and measures of abdominal adiposity and insulin-resistance were measured at an average age of 10.6 (±1.3) years. RESULTS Infants born IUGR experienced "catch-up growth" in the first 12 months of life at a rate of 3.58 kg/m² compared to 2.36 kg/m² in unexposed infants (P = 0.01). However, after 1 year of age, no differences in BMI growth velocity were observed. Nevertheless children exposed to IUGR had higher waist circumference (67.0 vs. 65.3 cm, P = 0.03), higher insulin (15.2 vs. 11.0 μU/ml, P = 0.0002), higher HOMA-IR (2.8 vs. 2.3, P = 0.03), and lower adiponectin levels (9.0 vs. 12.0 μg/ml, P = 0.003) in adolescence, independent of other childhood and maternal factors. CONCLUSIONS Our data from a contemporary US cohort suggests that children exposed to IUGR have increased abdominal fat and increased insulin resistance biomarkers despite no differences in BMI growth patterns beyond 12 months of age. These data provide further support for the fetal programming hypothesis.

Abstract
AIMS The sFlt-1/PlGF ratio has been evaluated as a diagnostic marker for preeclampsia (PE). The aim of this study was to explore the use of the sFlt-1/PlGF ratio as an aid in prediction for PE. METHODS 150 patients with a high risk for PE were enrolled in this prospective study. Groups were compared according to the pregnancy outcome: controls (n=114), intrauterine growth restriction (IUGR) (n=14) and PE (n=22) with subclassification early PE<34 weeks (n=6). Measurements of sFlt-1 and PlGF were performed on the automated Elecsys system. Statistical comparison of the sFlt-1/PlGF ratio in different outcome groups and a mixed model analysis using random intercept models were performed. RESULTS The sFlt-1/PlGF ratio was significantly higher in pregnancies complicated by PE up to 4 weeks before clinical diagnosis compared to controls (106.7 ± 47.7 vs. 21.0 ± 4.1; P=0.02). Levels of the sFlt-1/PlGF ratio were higher throughout pregnancy in women with IUGR compared to PE/control patients (intercept 1.57 vs. 1.30/0.67; P<0.05). The slope for the sFlt-1/PlGF ratio was significantly higher in PE and IUGR pregnancies compared to controls, indicating that a steep increase of the sFlt-1/PlGF ratio correlates with pathologic pregnancy outcomes. CONCLUSION The sFlt-1/PlGF ratio can identify pathologic pregnancy outcomes such as IUGR and PE before clinical diagnosis. Repeated measurements are necessary to assess the dynamics in serum values. The time-dependent slope of the sFlt-1/PlGF ratio is predictive for future pregnancy outcome and risk of developing preeclampsia.

Abstract
CONTEXT Endothelial colony-forming cells (ECFCs) are the only putative endothelial progenitor cells capable of vasculogenesis, and their dysfunction may represent a risk factor for cardiovascular disease. Intrauterine growth restriction (IUGR) is a pregnancy-related disorder associated with long-term cardiovascular risk. OBJECTIVE Our objective was to determine whether ECFCs derived from pregnancies complicated by IUGR exhibit altered vasculogenic potential. DESIGN AND SETTING This was a prospective cohort study; patients were recruited at St. Mary's Hospital, Manchester, United Kingdom. PARTICIPANTS Twenty-three women with normal pregnancies and 13 women with IUGR-complicated pregnancies at gestational ages above 37 weeks were included. MAIN OUTCOME MEASURES Vasculogenic capacity of rigorously characterized ECFCs was investigated in vivo by measuring blood vessel formation in collagen/fibronectin gels implanted in mice; proliferative, migratory, and chemotactic abilities were assessed in cell culture. Placental uptake of fetal ECFCs, assessed by differences in arterial and venous cord blood content, was determined by flow cytometry. RESULTS In vivo, IUGR ECFCs formed fewer blood vessels (P < .001) and capillaries (P = .001) compared with normal pregnancy-derived ECFCs. In culture conditions, IUGR ECFCs had reduced proliferation (P = .01) and migration (P = .007) and diminished chemotactic abilities to stromal cell-derived factor 1 (P = .007) coupled with reduced hypoxia-induced matrix metalloproteinase-2 release (P = .02). Finally, in IUGR pregnancies, the number of ECFCs was lower in arterial cord blood (P = .002) and placental uptake of cells was reduced (P < .001). CONCLUSIONS ECFCs derived from IUGR cord blood are rarefied and dysfunctional, resulting in diminished vasculogenic potential; this could be a cause of placental dysfunction in IUGR, with long-term postnatal implications for cardiovascular function in offspring.

Abstract
INTRODUCTION Calreticulin is a ubiquitously expressed protein that was detected in the circulation and is significantly increased in maternal blood during human pregnancy compared to the non-pregnant state. Calreticulin is further increased in the plasma of women with the pregnancy-related disorder pre-eclampsia compared to normotensive pregnancy. The aims of this study were to compare calreticulin in human pregnancy with calreticulin in rat pregnancy, and to compare calreticulin during fetal growth restriction with normal control pregnancies. METHODS Women were recruited who either had normal pregnancies or had pregnancies complicated with fetal growth restriction; maternal blood samples and placentas were collected. Blood was also taken from women who were not-pregnant. Growth restriction was induced in pregnant rats by uterine vessel ligation; blood and placental samples were collected. Blood was also taken from non-pregnant rats. Western blot was used to quantify the placental expression of calreticulin and the concentrations of calreticulin in plasma. RESULTS Although calreticulin was significantly increased in maternal plasma during human pregnancy compared to the non-pregnant state; it did not increase in plasma during rat pregnancy. These results suggest that there may be differences in the role of extracellular calreticulin in human compared to rat pregnancy. Calreticulin was not significantly altered in either placental extracts or maternal plasma in both the human and rat pregnancies complicated by fetal growth restriction compared to gestational matched control pregnancies. CONCLUSION This study found that there was no change in calreticulin during human pregnancy complicated with fetal growth restriction or when growth restriction is induced in rats.

Abstract
BACKGROUND Serum retinol binding protein (RBP4) is the binding protein for retinol, being delivered into the circulation through the carrier protein transthyretin (TTR) together with thyroxin (T4). RBP4 has also been recently indicated as a new adipokine implicated in insulin resistance and metabolism regulation. OBJECTIVE To investigate the role of RBP4 as early markers of fetal growth restriction (FGR) and preeclampsia (PE) in maternal serum during the first trimester of pregnancy. MATERIALS AND METHODS Retrospective case control study in patients between the 12th and the 14th week of gestation. RBP4, TTR and T4 concentration was assessed in maternal serum of three groups of women: 15 and 14 patients later developing respectively FGR and PE were compared with 11 patients having a normal pregnancy. RESULTS All women were Caucasian and the mean maternal age was 33.62 years (±5.50). RBP4 resulted lower in the FGR than in the control group (11.00 versus 16.00 µg/ml, p < 0.05) and than in the PE group (15.00 µg/ml, p = 0.075), both in bivariate and multivariate analysis. No difference was observed in TTR and T4 concentration. CONCLUSIONS RBP4 seems to play a role as early marker of FGR but not PE in first trimester maternal serum.

Abstract
Early-onset preeclampsia (EPE) is a severe form of preeclampsia that involves life-threatening neurological complications. However, the underlying mechanism by which EPE affects the maternal brain is not known. We hypothesized that plasma from women with EPE increases blood-brain barrier (BBB) permeability vs. plasma from women with late-onset preeclampsia (LPE) or normal pregnancy (NP) and investigated its underlying mechanism by perfusing cerebral veins from nonpregnant rats (n=6-7/group) with human plasma from women with EPE, LPE, or NP and measuring permeability. We show that plasma from women with EPE significantly increased BBB permeability vs. plasma from women with LPE or NP (P<0.001). BBB disruption in response to EPE plasma was due to a 260% increase of circulating oxidized LDL (oxLDL) binding to its receptor, LOX-1, and subsequent generation of peroxynitrite (P<0.001). A rat model with pathologically high lipid levels in pregnancy showed symptoms of preeclampsia, including elevated blood pressure, growth-restricted fetuses, and LOX-1-dependent BBB disruption, similar to EPE (P<0.05). Thus, we have identified LOX-1 activation by oxLDL and subsequent peroxynitrite generation as a novel mechanism by which disruption of the BBB occurs in EPE. As increased BBB permeability is a primary means by which seizure and other neurological symptoms ensue, our findings highlight oxLDL, LOX-1, and peroxynitrite as important therapeutic targets in EPE.
