Abstract
CONTEXT Lifestyle interventions have not efficaciously reduced complications caused by maternal weight on fetal growth, requiring insight into explanatory mediators. OBJECTIVE We hypothesized that maternal mediators, including adiponectin, leptin, insulin, and glucose, mediate effects of pregestational BMI (pBMI) and gestational weight gain (GWG) on birthweight and neonatal fat mass percentage (FM%) through placental weight and fetal mediators, including insulin levels (Ifv) and venous-arterial glucose difference (ΔGfva). Hypothesized confounders were maternal age, gestational age, and parity. METHODS A cross-sectional study of healthy mother-offspring-pairs (n = 165) applying the 4-vessel in vivo sampling method at Oslo University Hospital, Norway. We obtained pBMI, GWG, birthweight, and placental weight. FM% was available and calculated for a subcohort (n = 84). We measured circulating levels of adiponectin, leptin, glucose, and insulin and performed path analysis and traditional mediation analyses based on linear regression models. RESULTS The total effect of pBMI and GWG on newborn size was estimated to be 30 g (range, 16-45 g) birthweight and 0.17 FM% (range, 0.04-0.29 FM%) per kg∙m-2 pBMI and 31 g (range, 18-44 g) and 0.24 FM% (range, 0.10-0.37 FM%) per kg GWG. The placental weight was the main mediator, mediating 25-g birthweight and 0.11 FM% per kg∙m-2 pBMI and 25-g birthweight and 0.13 FM% per kg GWG. The maternal mediators mediated a smaller part of the effect of pBMI (3.8-g birthweight and 0.023 FM% per kg∙m-2 pBMI) but not GWG. CONCLUSION Placental weight was the main mediator linking pBMI and GWG to birthweight and FM%. The effect of pBMI, but not GWG, on birthweight and FM%, was also mediated via the maternal and fetal mediators.

Abstract
INTRODUCTION Monitoring of renal function in acute kidney injury in the pediatric population is complicated by the lack of age-related reference values of new biomarkers. Urinary netrin-1 is a new marker to demonstrate early kidney damage. Netrin-1 has a molecular mass of 72 kDa. It is therefore unlikely that it is filtered by the glomerulus under normal conditions. However, netrin-1 is highly induced after acute and chronic kidney injury and excreted in urine in humans. The aim of the study was to determine the normal concentrations of urinary netrin-1 in healthy full-term newborns. MATERIAL AND METHODS The study included 88 healthy full-term neonates (51 boys and 37 girls) born from normal, uncomplicated pregnancies. The concentration of netrin-1 was determined in urine obtained on the first or second day of life with a commercially available ELISA kit. RESULTS The urinary concentration of netrin-1 in newborns was independent of gender and time of urine collection. We found a negative correlation between both the urinary netrin-1 concentration and urinary netrin-1 concentration after normalization for urinary creatinine and the birth weight. CONCLUSIONS This is the first study showing the urinary netrin-1 concentration in healthy full-term newborns. Future investigation is needed to confirm its potential role as a marker of kidney function in this age group.

Abstract
Rationale: Maternal obesity is associated with asthma in the offspring. Whether cord blood leptin is associated with risk of asthma in offspring is unclear.Objectives: To assess whether cord blood leptin from women with pregestational obesity predict preschool asthma.Methods: In this birth cohort study, we divided pregnant women into three weight categories during the first obstetric visit: normal (NL), overweight (OW), and obese (OB).Results: We followed the offspring recording atopy, wheezing, and other respiratory illnesses through 30 months of age. Cord blood and peripheral blood at 30 months of age were taken to measure cytokines, adipokines, metabolic biomarkers, and specific immunoglobulin E. Adjusted regression models were used to evaluate the association between maternal obesity and offspring asthma risk, defined by a positive Asthma Predictive Index. Three hundred thirty-nine mothers were recruited; 140 offspring were born from NL, 80 from OW, and 119 from OB mothers. OB women were older and less educated and had higher parity and higher C-section frequency. Offspring from OB women had higher birthweight, head circumference, and placental weight compared with other groups. The proportion of Asthma Predictive Index positive at 30 months of age was 12.2% in the NL, 14.7% in the OW, and 16.8% in the OB group (P = 0.18). Offspring from OB women had higher leptin, leptin/adiponectin ratio, interleukin-10, and insulin than the OW group and higher leptin than the NL group. In the adjusted analysis, offspring from OB mothers with high cord blood leptin had increased risk of asthma (adjusted odds ratio, 1.30; 95% confidence interval, 1.1-1.55; P = 0.003).Conclusions: Offspring from obese mothers with high cord blood leptin have 30% higher asthma risk at age 3.Clinical trial registered with ClinicalTrials.gov (NCT02903134).

Abstract
Objectives: To evaluate maternal and fetal Leptin and IL33 concentrations in pregnancy complicated by obesity and preeclampsia.Study design: A case-control study including 35 subjects with obesity (18 normotensive and 17 preeclamptic) and 47 normal weight controls (42 normotensive and 5 preeclamptic).Main outcome measures: Leptin and IL33 concentrations in maternal serum during pregnancy and in cord blood; uterine artery and umbilical artery Doppler velocimetry.Results: Subjects with obesity who developed preeclampsia had higher first trimester maternal (41.5, interquartile range (IQR) = 15.7-65.1 ng/ml) Leptin concentrations compared to either normal weight with (25, IQR = 20.4-25.8 ng/ml) and without hypertension (14.26, IQR = 8.2-22.8) (p < .05) or normotensive subjects with obesity (30.3, IQR = 10.4-38.4) (p < .05). Subjects with obesity who developed preeclampsia (2.4, IQR = 1.7-3.2 pg/ml) or not (1.4, IQR = 0.8-2 pg/ml) had lower first trimester maternal IL33 levels when compared to controls without hypertension (4.8, IQR = 2.9-5.9 pg/ml) (p < .001). Cord blood Leptin and IL33 concentrations were significantly correlated to third trimester maternal concentrations (Spearman rho = 0.51, p < .001 and Spearman rho = 0.68, p < .001, respectively). Uterine artery pulsatility index (PI) were significantly and directly correlated with maternal Leptin levels (p < .002) and inversely and statistically correlated with maternal IL33 concentrations (p < .001).Conclusions: Compared to lean controls, pregnant subjects with obesity had higher serum Leptin and lower IL33 concentrations at first trimester and during pregnancy. This difference persisted also for those who later developed preeclampsia. The relationship between maternal serum levels of Leptin and IL33 with uterine artery Doppler pulsatility index strongly suggests a role of these two markers in early placentation.

Abstract
INTRODUCTION Folate is required for fetal, placental and maternal tissue growth during pregnancy. A decline in maternal circulating folate concentrations and an increase in total homocysteine (a non-specific indicator of folate deficiency) have been observed with the progression of pregnancy. However, the role of folate in the third trimester of pregnancy is not clear and folate status in late pregnancy has not so far been widely analyzed. The main aim of this retrospective cross-sectional study was to determine the folate concentrations in amniotic fluid and in maternal and umbilical cord blood serum derived during delivery. MATERIAL AND METHODS This study was conducted on 175 pregnant Polish women (white/Caucasian) aged between 17 and 42 years. Only pregnancies without birth defects were included in this study. Amniotic fluid, maternal serum, and umbilical cord blood samples were collected during vaginal delivery or cesarean section. Folate concentration was determined using a microbiological assay. RESULTS Strong correlations were observed between the concentrations of folate in amniotic fluid and maternal serum (rho = 0.67, p < 0.001) and amniotic fluid and cord blood serum (rho = 0.49, p < 0.001) and between maternal serum and cord blood serum (rho = 0.67, p < 0.001). Folate concentrations in amniotic fluid were significantly associated with maternal age (rho = 0.19, p < 0.05). Pre-pregnancy body mass index and maternal weight/neonatal birth weight ratio were independent predictors of folate concentrations in maternal serum (β = 0.33, p < 0.05; β = -0.19, p < 0.05) and amniotic fluid (β = 0.28, p < 0.05; β = -0.19, p < 0.05) in late pregnancy. CONCLUSIONS Folate concentrations in amniotic fluid are associated with maternal and neonatal folate status peripartum in healthy women.

Abstract
Two-thirds of pregnant women exceed gestational weight gain recommendations. Excessive gestational weight gain (EGWG) appears to be associated with offspring's complications induced by mechanisms that are still unclear. The aim of this study was to investigate whether umbilical cord leptin (UCL) and ghrelin (UCG) concentrations are altered in full-term neonates born to EGWG mothers and whether neonatal anthropometric measurements correlate with UCL and UCG levels and maternal serum ghrelin and leptin as well as urine ghrelin concentrations. The study subjects were divided into two groups, 28 healthy controls and 38 patients with EGWG. Lower UCL and UCG levels were observed in neonates born to healthy mothers but only in male newborns. In the control group UCG concentrations correlated positively with neonatal birth weight, body length and head circumference. In the control group maternal serum ghrelin levels correlated negatively with neonatal birth weight, body length and head circumference as well as positively with chest circumference. In the EGWG group UCG concentrations correlated negatively with neonatal birth weight and birth body length. UCL correlated positively with birth body length in EGWG group and negatively with head circumference in the control group. In conclusion, EGWG is associated with disturbances in UCL and UCG concentrations.

Abstract
INTRODUCTION The aim of this meta-analysis was to summarize the evidence on the serum/plasma leptin concentrations in breast cancer (BC) patients, as well as the associations between leptin G-2548A gene polymorphisms and susceptibility to BC. MATERIAL AND METHODS Potentially relevant studies about serum/plasma leptin levels and leptin G-2548A gene polymorphism were selected using the electronic databases PubMed, EMBASE and The Cochrane Library (from January 1 1995 to Jun 30 2017, no language restrictions). The potential sources of heterogeneity were assessed by the Q statistic and quantified using I2 ; publication bias was qualitatively assessed by funnel plot and quantitatively assessed by Egger's linear regression test. RESULTS A total of 1141 articles were retrieved after database searches, and 27 studies with 9516 subjects (4542 BC patients/4974 controls) were finally included. The results indicated that BC patients had significantly higher leptin levels compared with healthy controls (SMD = 1.65, 95% CI: 1.21-2.09, p < 0.001), but there was no association between leptin G-2548A polymorphism and BC (OR = 1.05, 95% CI: 0.80-1.39, p = 0.722). Subgroup analyses demonstrated increased leptin levels in BC patients of different region, race, body mass index and waist circumference. CONCLUSIONS Our results revealed a significantly higher leptin level in BC patients than in healthy controls, but no association between leptin G-2548A polymorphism and BC susceptibility was found.

Serum Concentration of Leptin in Pregnant Adolescents Correlated with Gestational Weight Gain, Postpartum Weight Retention and Newborn Weight/Length. Nutrients 2017; 9:nu9101067. [PMID: 28953229 PMCID: PMC5691684 DOI: 10.3390/nu9101067] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2017] [Revised: 09/06/2017] [Accepted: 09/12/2017] [Indexed: 12/21/2022] Open
Abstract
Introduction: Gestational weight gain is an important modifiable factor known to influence fetal outcomes including birth weight and adiposity. Leptin is normally correlated with adiposity and is also known to increase throughout pregnancy, as the placenta becomes a source of leptin synthesis. Several studies have reported positive correlations between cord blood leptin level and either birthweight or size for gestational age, as well as body mass index (BMI). Objective: To determine the correlation of prenatal leptin concentration in pregnant adolescents with their gestational weight gain, postpartum weight retention, and weight/length of their newborn. Methods: A cohort study was conducted on pregnant Mexican adolescents from Gestational Week 26–28 to three months postpartum (n = 168 mother–child dyads). An anthropometric assessment was made of each pregnant adolescent, and the serum level of leptin and the intake of energy were determined. The newborn was evaluated each month during postpartum. Clinical records were reviewed to obtain sociodemographic data. Bivariate correlations, tests for repeating measurements and logistic regression models were performed. Results: Leptin concentration gradually increased during the third trimester of pregnancy. At Gestation Week 36, leptin level correlated with gestational weight gain. When comparing adolescents that had the lowest and highest concentration of leptin, the former presented a mean of 6 kg less in gestational weight gain (inter-subject leptin concentration, p = 0.001; inter-subject energy intake, p = 0.497). Leptin concentration and gestational weight gain exerted an effect on the weight of the newborn (inter-subject leptin concentration for Week 32, p = 0.024; inter-subject gestational weight gain, p = 0.011). Newborn length was associated with leptin concentration at Week 28 (leptin effect, p = 0.003; effect of gestational weight gain, p = 0.722). Conclusions: Pregnant adolescents with leptin concentration over 20 ng/mL showed a greater gestational weight gain. Leptin concentration correlated with length and weight of the newborn.

Abstract
INTRODUCTION Strategies to limit excessive maternal gestational weight gain could also have positive health effects for the offspring. This study informs us on the effect of an antenatal lifestyle intervention on offspring body mass index (BMI) trajectory until age five. MATERIAL AND METHODS A secondary analysis of a randomized controlled trial aimed at reducing gestational weight gain, set in Ørebro, Sweden (Clinical Trials.gov Id NCT00451425). Offspring were followed with standardized measures of weight and height until age five. Mean BMI z-score and proportion (%) of over- and undernutrition (BMI z-score > ± 2 standard deviations) was compared between groups. Risk estimates for obesity at age five were analyzed in relation to maternal gestational weight gain and prepregnancy BMI as a secondary outcome. RESULTS We analyzed 374 children at birth and 300 at age five. No significant difference in mean BMI z-score was seen at birth (0.68 (I) vs 0.56 (C), p = 0.242) or at age five (0.34 (I) vs 0.26 (C), p = 0.510) and no significant difference in proportion of over- or undernutrition was seen. Excessive maternal gestational weight gain was an independent risk factor for offspring obesity at birth (OR = 4.51, p < 0.001) but not at age five. Maternal obesity was an independent risk factor for offspring obesity at age five (OR = 4.81, p = 0.006). CONCLUSIONS Our composite antenatal lifestyle intervention did not significantly reduce the risk of obesity in offspring up until age five.
