[PMID: 39018608 DOI: 10.1016/j.placenta.2024.07.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2023] [Revised: 07/07/2024] [Accepted: 07/10/2024] [Indexed: 07/19/2024]
Abstract
INTRODUCTION Poor placental angiogenesis is associated with several pregnancy complications including fetal growth restriction (FGR), which causes low birth weight (LBW) babies to have a high risk of growth disorders and metabolic disorders in adulthood. Recent research using syncytin knock-out mice showed significant disruption in the growth of placental vascularization. Syncytin-1 which encoded by ERVW-1 gene, is proposed to have a role in placental angiogenesis, but its relationship with other proangiogenic factors such as vascular endothelial growth factor (VEGF) in the placenta of LBW babies has not yet been determined. By knowing the mechanisms of FGR, more proactive preventive and therapeutic measures can be taken in the future. This study aimed to determine the expression of ERVW-1, proangiogenic gene VEGF and its receptor (FLT-1), and hypoxia inducible factor-1 (HIF-1) in LBW placentas, and investigate the relationship between these genes' expression in the placenta of LBW babies. METHODS Total RNA was extracted from placental tissue. Total RNA is used as a cDNA synthesis template, followed by qRT-PCR. Correlations of ERVW-1, VEGF, FLT-1 and HIF-1 genes' expression were analyzed by linear regression. RESULTS The age and body mass index of mothers with LBW and normal birth weight (NBW) babies were not significantly different. ERVW-1 expression in LBW placentas was lower than in NBW placentas, but VEGF, FLT-1 and HIF-1 expressions were higher. ERVW-1 was negatively correlated with HIF-1 and VEGF. DISCUSSION Low expression of ERVW-1 in the placenta of LBW babies may result in impaired placental angiogenesis and possibly lead to hypoxia.

Placental size at gestational week 27 and 37: The associations with pulsatility index in the uterine and the fetal-placental arteries. Placenta 2024; 145:45-50. [PMID: 38064937 DOI: 10.1016/j.placenta.2023.11.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Revised: 11/08/2023] [Accepted: 11/25/2023] [Indexed: 01/12/2024]
Abstract
INTRODUCTION Fetal growth restriction is known to be related to decreased fetal and placental blood flow. It is not known, however, whether placental size is related to fetal and placental blood flow. We studied the correlations of intrauterine placental volume and placental-fetal-ratio with pulsatility index (PI) in the uterine arteries, fetal middle cerebral artery, and umbilical artery. METHODS We followed a convenience sample of 104 singleton pregnancies, and we measured placental and fetal volumes using magnetic resonance imaging (MRI) at gestational week 27 and 37 (n = 89). Pulsatility index (PI) was measured using Doppler ultrasound. We calculated cerebroplacental ratio as fetal middle cerebral artery PI/umbilical artery PI and placental-fetal-ratio as placental volume (cm3)/fetal volume (cm3). RESULTS At gestational week 27, placental volume was negatively correlated with uterine artery PI (r = -0.237, p = 0.015, Pearson's correlation coefficient), and positively correlated with fetal middle cerebral artery PI (r = 0.247, p = 0.012) and cerebroplacental ratio (r = 0.208, p = 0.035). Corresponding correlations for placental-fetal-ratio were -0.273 (p = 0.005), 0.233 (p = 0.018) and 0.183 (p = 0.064). Umbilical artery PI was not correlated with placental volume. At gestational week 37, we found weaker and no significant correlations between placental volume and the pulsatility indices. CONCLUSIONS Our results suggest that placental size is correlated with placental and fetal blood flow at gestational week 27.

Abstract
Obstructive sleep apnea (OSA) during pregnancy is characterized by episodes of intermittent hypoxia (IH) during sleep, resulting in adverse health outcomes for mother and offspring. Despite a prevalence of 8-20% in pregnant women, this disorder is often underdiagnosed.We have developed a murine model of gestational OSA to study IH effects on pregnant mothers, placentas, fetuses, and offspring. One group of pregnant rats was exposed to IH during the last 2 weeks of gestation (GIH). One day before the delivery date, a cesarean section was performed. Other group of pregnant rats was allowed to give birth at term to study offspring's evolution.Preliminary results showed no significant weight differences in mothers and fetuses. However, the weight of GIH male offspring was significantly lower than the controls at 14 days (p < 0.01). The morphological study of the placentas showed an increase in fetal capillary branching, expansion of maternal blood spaces, and number of cells of the external trophectoderm in the tissues from GIH-exposed mothers. Additionally, the placentas from the experimental males were enlarged (p < 0.05). Further studies are needed to follow the long-term evolution of these changes to relate the histological findings of the placentas with functional development of the offspring in adulthood.

Abstract
Increased fetal heart rate variability (FHRV) in intrapartum cardiotocographic recording has been variably defined and poorly understood, limiting its clinical utility. Both preclinical (animal) and clinical (human) evidence support that increased FHRV is observed in the early stage of intrapartum fetal hypoxaemia but can also be observed in a subset of fetuses during the preterminal stage of repeated hypoxaemia. This review of available evidence provides data and expert opinion on the pathophysiology of increased FHRV, its clinical significance and a stepwise approach regarding the management of this pattern, and propose recommendations for standardisation of related terminology.

Abstract
Prenatal hypoxia is a common complication of pregnancy and is associated with detrimental health outcomes, such as impaired cardiac and vascular function, in adult offspring. Exposure to prenatal hypoxia reportedly impacts the reproductive system of female offspring. Whether exposure to prenatal hypoxia influences pregnancy adaptations and outcomes in these female offspring is unknown. We hypothesised that prenatal hypoxia impairs uterine artery adaptations in pregnancies of the adult offspring. Pregnancy outcomes and uterine artery function were assessed in 14-16 weeks old non-pregnant and late pregnant (gestational day 20; term = 22 days) adult female offspring born to rats exposed to prenatal normoxia (21% oxygen) or hypoxia (11% oxygen, between days 15-21 of gestation). Compared with normoxia controls, prenatal hypoxia was associated with pregnant adult offspring having reduced placental weights in their litters, and uterine artery circumferential stress that increased with pregnancy. Overall, prenatal hypoxia adversely, albeit mildly, compromised pregnancies of adult offspring.

Abstract
OBJECTIVES To examine whether the risk of cardiovascular disease (CVD) in women with pre-eclampsia is modified by very low or very high offspring birth weight. Further, we studied whether diabetes in pregnancy modified this risk. DESIGN Nationwide cohort study. SETTING Norwegian population registries. PARTICIPANTS 618 644 women who gave birth to their first child during 1980-2009. METHODS The women were followed from delivery until the development of CVD or censoring, by linkage of the Medical Birth Registry of Norway to the Cardiovascular Disease in Norway project, and the Norwegian Cause of Death Registry. PRIMARY OUTCOME MEASURE CVD. RESULTS Compared with normotensive women with normal offspring birth weight, women with pre-eclampsia had increased risk of CVD (HR 2.16; 95% CI 2.05 to 2.26). The CVD risk was even higher when pre-eclampsia was accompanied with a large for gestational age offspring (LGA, z-score >2.0) (HR 2.57; 95% CI 2.08 to 3.18). Women with pre-eclampsia and a small for gestational age offspring (SGA, z-score <-2.0) had an HR of 1.54 (95% CI 1.23 to 1.93) compared with normotensive women with normal offspring birth weight.Also, women with diabetes had increased CVD risk, but no additional risk associated with an LGA or SGA offspring. CONCLUSIONS Women with pre-eclampsia and an LGA offspring had higher risk of CVD than pre-eclamptic women with a normal weight (z-score -2.0 to 2.0) or SGA offspring. These findings suggest that factors causing pre-eclampsia and an LGA offspring are also linked to development of CVD.

Abstract
Perinatal hypoxia is still one of the greatest threats to the newborn child, even in developed countries. However, there is a lack of works which summarize up-to-date information about that huge topic. Our review covers a broader spectrum of recent results from studies on mechanisms leading to hypoxia-induced injury. It also resumes possible primary causes and observed behavioral outcomes of perinatal hypoxia. In this review, we recognize two types of hypoxia, according to the localization of its primary cause: environmental and placental. Later we analyze possible pathways of prenatal hypoxia-induced injury including gene expression changes, glutaminergic excitatory damage (and a role of NMDA receptors in it), oxidative stress with ROS and RNS production, inflammation and apoptosis. Moreover, we focus on the impact of these pathophysiological changes on the structure and development of the brain, especially on its regions: corpus striatum and hippocampus. These brain changes of the offspring lead to impairments in their postnatal growth and sensorimotor development, and in their motor functions, activity, emotionality and learning ability in adulthood. Later we compare various animal models used to investigate the impact of prenatal and postnatal injury (hypoxic, ischemic or combinatory) on living organisms, and show their advantages and limitations.

Abstract
OBJECTIVES Placental hypoxia is a hallmark of preeclampsia. SNP rs479200 in the EGLN1 gene is associated with reduced responsiveness to hypoxia. Whether this translates into an association between SNP rs479200 and preeclampsia is not known. We evaluated the association of SNP rs479200 (T>C) with the risk of preeclampsia. METHODS This case-control study involved 600 pregnant women of whom 300 were preeclamptic and 300 were normotensive. SNP rs479200 was genotyped by PCR-RFLP method. RESULT Minor allele frequency was 44% in preeclamptic women and 53% in normotensive pregnant women (P = 1.8 × 10-3; odds ratio = 1.43). The odds ratio was heterogeneous when compared after categorization of the preeclamptic group into clinical sub-groups. The association was significant with both mild (P = 6.2 × 10-5) and severe (3.8 × 10-3) preeclampsia. However, the odds ratio was 0.52 for mild preeclampsia and 1.43 for severe preeclampsia. CONCLUSION The minor allele of SNP rs479200 is associated with the predisposition to preeclampsia. This association underlines the importance of oxygen sensing in the pathogenesis of preeclampsia.

Abstract
Development of the human placenta is critical for a successful pregnancy. The placenta allows the exchange of oxygen and carbon dioxide and is crucial to manage acid-base balance within a narrow pH. It is known that low pH levels are a risk of apoptosis in several tissues. However, there has been little discussion about the effect of acidic stress in the placenta. Leptin is produced by the placenta with a trophic autocrine effect. Previous results of our group have demonstrated that leptin prevents apoptosis of trophoblast cells under different stress conditions such as serum deprivation and hyperthermia. The purpose of the present work is to evaluate acidic stress consequences in trophoblast explant survival and to determine leptin action in these conditions. For this objective, term human trophoblast explants were cultured at physiological pH (pH 7.4) and at acidic pH (pH 6.8) in the presence or absence of leptin. Western blot assays were performed to study the abundance of active caspase-3 and the p89 fragment of PARP-1. Pro-apoptotic and pro-survival members of Bcl-2 family, as Bax, t-Bid, and Bcl-2, were studied. Moreover, p53 pathway was also evaluated including Mdm-2, the main p53 regulator. Active caspase-3 and cleaved PARP-1 abundances were increased at low extracellular pH. Moreover, t-Bid levels were also augmented as well as p53 expression and phosphorylation on S46. Leptin treatment prevents the consequences of acidosis, decreasing p53 expression and increasing Mdm-2 expression. In summary, this work demonstrated for first time that low pH induces apoptosis of human trophoblast explants involving apoptotic intrinsic pathway, and leptin impairs this effect.

Abstract
Hypoxia may influence normal and different pathological processes. Low oxygenation activates a variety of responses, many of them regulated by hypoxia-inducible factor 1 complex, which is mostly involved in cellular control of O2 consumption and delivery, inhibition of growth and development, and promotion of anaerobic metabolism. Hypoxia plays a significant physiological role in fetal development; it is involved in different embryonic processes, for example, placentation, angiogenesis, and hematopoiesis. More recently, fetal hypoxia has been associated directly or indirectly with fetal programming of heart, brain, and kidney function and metabolism in adulthood. In this review, the role of hypoxia in fetal development, placentation, and fetal programming is summarized. Hypoxia is a basic mechanism involved in different pregnancy disorders and fetal health developmental complications. Although there are scientific data showing that hypoxia mediates changes in the growth trajectory of the fetus, modulates gene expression by epigenetic mechanisms, and determines the health status later in adulthood, more mechanistic studies are needed. Furthermore, if we consider that intrauterine hypoxia is not a rare event, and can be a consequence of unavoidable exposures to air pollution, nutritional deficiencies, obesity, and other very common conditions (drug addiction and stress), the health of future generations may be damaged and the incidence of some diseases will markedly increase as a consequence of disturbed fetal programming.

Abstract
PURPOSE OF THE STUDY Heat shock proteins (Hsp) are evolutionary conserved molecules with a chaperone role in cell survival. We hypothesized that cord blood concentrations of molecules reflecting fetal cardiac muscle insult, including Hsp, troponins cTnI and cTnT, and glycol-phosphorylase BB (GP-BB) would be elevated in pregnancies complicated by gestational diabetes (GDM) or preeclampsia (PIH) compared to healthy controls. MATERIALS AND METHODS Pregnant women admitted for delivery at >28 weeks were divided into four groups: healthy patients delivered vaginally (VAG), healthy patients delivered by c-section (CS), patients with PIH, and patients with GDM. Demographics, clinical characteristics, and cord blood concentrations of Hsp, troponins cTnI and cTnT, and GP-BB were compared between groups. Statistical analyses included t-test, Chi square, and Wilcoxon rank sum as appropriate. RESULTS cTnI concentrations were significantly higher in the PIH group compared to the GDM and VAG groups and they were higher in the CS group compared to the VAG group. Concentrations of Hsp70 were higher in the GDM group compared to the VAG and CS groups. Concentration of GP-BB was higher in the PIH group compared to the VAG group. CONCLUSIONS GP-BB and cTNI are the most sensitive markers for PIH-related fetal myocyte injury as is Hsp70 in pregnancies complicated by GDM.
