Abstract
Steroid hormones have diverse roles in pregnancy; some help stabilise pregnancy and influence the stability of pregnancy and the onset of labour. Changes and disorders in steroidogenesis may be involved in several pregnancy pathologies. To date, only a few studies have performed a very limited steroid analysis in multiple pregnancies. Our teams investigated multiple pregnancies regarding the biosynthesis, transport, and effects of steroids. We recruited two groups of patients: pregnant women with multiple pregnancies as the study group, and a control singleton pregnancies group. Blood samples were drawn from the participants and analysed. Information about the mother, foetus, delivery, and newborn was extracted from medical records. The data were then analysed. The gestational age of twin pregnancies during delivery ranged from 35 + 3 to 39 + 3 weeks, while it was 38 + 1 to 41 + 1 weeks for the controls. Our findings provide answers to questions regarding the steroidome in multiple pregnancies. Results demonstrate differences in the steroidome between singleton and twin pregnancies. These were based on the presence of two placentae and two foetal adrenal glands, both with separate enzymatic activity. Since every newborn was delivered by caesarean section, analysis was not negatively influenced by changes in the steroid metabolome associated with the spontaneous onset of labour.

Abstract
INTRODUCTION Following the detection of fetal growth restriction, there is no consensus about the criteria that should trigger delivery in the late preterm period. The consequences of inappropriate early or late delivery are potentially important yet practice varies widely around the world, with abnormal findings from fetal heart rate monitoring invariably leading to delivery. Indices derived from fetal cerebral Doppler examination may guide such decisions although there are few studies in this area. We propose a randomised, controlled trial to establish the optimum method of timing delivery between 32 weeks and 36 weeks 6 days of gestation. We hypothesise that delivery on evidence of cerebral blood flow redistribution reduces a composite of perinatal poor outcome, death and short-term hypoxia-related morbidity, with no worsening of neurodevelopmental outcome at 2 years. METHODS AND ANALYSIS Women with non-anomalous singleton pregnancies 32+0 to 36+6 weeks of gestation in whom the estimated fetal weight or abdominal circumference is <10th percentile or has decreased by 50 percentiles since 18-32 weeks will be included for observational data collection. Participants will be randomised if cerebral blood flow redistribution is identified, based on umbilical to middle cerebral artery pulsatility index ratio values. Computerised cardiotocography (cCTG) must show normal fetal heart rate short term variation (≥4.5 msec) and absence of decelerations at randomisation. Randomisation will be 1:1 to immediate delivery or delayed delivery (based on cCTG abnormalities or other worsening fetal condition). The primary outcome is poor condition at birth and/or fetal or neonatal death and/or major neonatal morbidity, the secondary non-inferiority outcome is 2-year infant general health and neurodevelopmental outcome based on the Parent Report of Children's Abilities-Revised questionnaire. ETHICS AND DISSEMINATION The Study Coordination Centre has obtained approval from London-Riverside Research Ethics Committee (REC) and Health Regulatory Authority (HRA). Publication will be in line with NIHR Open Access policy. TRIAL REGISTRATION NUMBER Main sponsor: Imperial College London, Reference: 19QC5491. Funders: NIHR HTA, Reference: 127 976.

Abstract
Steroid biosynthesis occurs in adrenal, gonadal, brain, liver, and placental tissues. Depending on the location of their activity, steroids can be divided into two groups - intracellular and extracellular. Intracellular ones act as transcription factors, suppressing or activating gene expression - they have a so-called genomic effect and therefore their onset of action is slow. Steroids acting extracellularly (non-genome effect) bind to neurotransmitter receptors located on the cytoplasmic cell membrane and thus affect the permeability of the ion channels, the effect of which is much faster, and we refer to them as neuroactive steroids or neurosteroids. While neuroactive steroids can be produced in different tissues of the body, or can be administered externally, neurosteroids are synthetized in cells of the nervous system. Some neuroactive steroids whose levels are extremely elevated in pregnancy (progesterone and its metabolites) are crucial in stabilizing pregnancy and changes in their concentration may influence the onset of parturition. Steroidogenic disorders may be involved in a number of pregnancy pathologies such as premature birth, pre-eclampsia, intrahepatic cholestasis in pregnancy, etc. Our research in collaboration with the Department of Steroids and Proteofactors of the Institute of Endocrinology in Prague also focuses on the investigation of multiple pregnancies in terms of biosynthesis, transport, and the effects of steroids. Studies available in the literature so far have not provided a comprehensive analysis of the steroidome in children and mothers in multiple pregnancies. The aim of our research is therefore to clarify the relationships between fetuses and mothers and between fetuses from the point of view of steroid synthesis and transport as well as the physiology and pathophysiology of human pregnancy and childbirth.

Abstract
As gestational diabetes mellitus (GDM) is both a frequent and serious complication, steroid levels in pregnancy are extremely elevated and their role in pregnancy is crucial, this review focuses on the role of steroids and related substances in the GDM pathophysiology. Low SHBG levels are associated with insulin resistance and hyperinsulinemia, while also predicting a predisposition to GDM. Other relevant agents are placental hormones such as kisspeptin and CRH, playing also an important role beyond pregnancy, but which are synthesized here in smaller amounts in the hypothalamus. These hormones affect both the course of pregnancy as well as the synthesis of pregnancy steroids and may also be involved in the GDM pathophysiology. Steroids, whose biosynthesis is mainly provided by the fetal adrenal glands, placenta, maternal adrenal glands, and both maternal and fetal livers, are also synthesized in limited amounts directly in the pancreas and may influence the development of GDM. These substances involve the sulfated Δ5 steroids primarily acting via modulating different ion channels and influencing the development of GDM in different directions, mostly diabetogenic progesterone and predominantly anti-diabetic estradiol acting both in genomic and non-genomic way, androgens associated with IR and hyperinsulinemia, neuroactive steroids affecting the pituitary functioning, and cortisol whose production is stimulated by CRH but which suppresses its pro-inflammatory effects. Due to the complex actions of steroids, studies assessing their predominant effect and studies assessing their predictive values for estimating predisposition to GDM are needed.

Abstract
Steroid profiling helps various pathologies to be rapidly diagnosed. Results from analyses investigating steroidogenic pathways may be used as a tool for uncovering pathology causations and proposals of new therapeutic approaches. The purpose of this study was to address still underutilized application of the advanced GC-MS/MS platform for the multicomponent quantification of endogenous steroids. We developed and validated a GC-MS/MS method for the quantification of 58 unconjugated steroids and 42 polar conjugates of steroids (after hydrolysis) in human blood. The present method was validated not only for blood of men and non-pregnant women but also for blood of pregnant women and for mixed umbilical cord blood. The spectrum of analytes includes common hormones operating via nuclear receptors as well as other bioactive substances like immunomodulatory and neuroactive steroids. Our present results are comparable with those from our previously published GC-MS method as well as the results of others. The present method was extended for corticoids and 17alpha-hydroxylated 5alpha/ß-reduced pregnanes, which are useful for the investigation of alternative "backdoor" pathway. When comparing the analytical characteristics of the present and previous method, the first exhibit by far higher selectivity, and generally higher sensitivity and better precision particularly for 17alpha-hydroxysteroids.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is a frequent liver disorder, mostly occurring in the third trimester. ICP is not harmful to the mothers but threatens the fetus. The authors evaluated steroid alterations in maternal and mixed umbilical blood to elucidate their role in the ICP development. Ten women with ICP were included in the study. Steroids in the maternal blood were measured by Gas Chromatography-Mass Spectrometry (GC-MS) (n=58) and RIA (n=5) at the diagnosis of ICP, labor, day 5 postpartum, week 3 postpartum and week 6 postpartum. The results were evaluated by ANOVA consisting of the subject factor, between subject factors ICP, gestational age at the diagnosis of ICP and gestational age at labor, within-subject factor Stage and ICP × Stage interaction. The 17 controls were firstly examined in the week 36 of gestation. ICP patients showed reduced CYP17A1 activity in the C17,20 lyase step thus shifting the balance between the toxic conjugated pregnanediols and harmless sulfated 5alpha/beta-reduced-17-oxo C19 steroids. Hence, more toxic metabolites originating in maternal liver from the placental pregnanes may penetrate backward to the fetal circulation. As these alterations persist in puerperium, the circulating steroids could be potentially used for predicting the predisposition to ICP even before next pregnancy.

Abstract
OBJECTIVE To summarize available data concerning the role of maternal imunity and woman´s microbiome in the pathogenesis of preterm labor and their use in clinical practice. SETTING Department of Obstetrics and Gynecology od the First Faculty of Medicine, Charles University in Prague, and General Teaching Hospital. DESIGN Review article. METHODS Compilation od published data from scientific literature. CONCLUSION Preterm labor complicates approximately 10% of all pregnancies and represents a serious medical, social and economic problem. In the past, a lot of causes of preterm labor were discussed; infection, uteroplacental ischemia, decidual hemorrhage, uterine overdistension, cervical disease and maternal-fetal tolerance disorder were considered the most common. However, chronic inflammation seems to be the common pathogenic process underlying preterm labor, irrespective of the original stimulus. Currently, impaired maternal-fetal immunological tolerance represents most discussed topic. Growing scientific evidence suggests that the immune regulation of the maternal-fetal interface is the result of the coordinated interaction among maternal microbiota, trophoblast and maternal cellular components. From this view we understand preterm labor as a result of disruption of this process.

Abstract
OBJECTIVE To describe the role of T-regulatory lymphocytes in pathogenesis of preterm delivery. SETTING Department of Obstetrics and Gynecology, General University Hospital and 1st Medical Faculty, Charles University, Prague. METHOD T-regulatory lymphocytes modulate the immune system, secure the tolerance to own antigens and prevent autoimmune disease. During pregnancy is maternal immunity in contact with the semi-allogeneic fetus due to the fetomaternal crosstalk. It seems that maternal immunity and T-regulatory lymphocytes have an effect on premature birth and other pregnancy pathologies. According to the latest data, their role in the immunomodulation of pregnant women seems to be very significant, although we still do not understand many mechanisms.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is a disorder of liver function, commonly occurring in the third trimester but sometimes also as soon as the end of the second trimester of pregnancy. Symptoms of this disorder include pruritus, plus abnormal values of bile acids and hepatic transaminases. After birth, symptoms disappear and liver function returns to normal. Though ICP is relatively non-complicated and often symptomatically mild from the point-of-view of the mother, it presents a serious risk to the fetus, making this disease the subject of great interest. The etiology and pathogenesis of ICP is multifactorial and as yet not fully elucidated. Hormonal factors likely play a significant role, along with genetic as well as exogenous factors. Here we summarize the knowledge of changes in steroid hormones and their role in the development of intrahepatic cholestasis of pregnancy. In addition, we consider the role of exogenous factors as possible triggers of steroid hormone changes, the relationship between metabolic steroids and bile acids, as well as the combination of these factors in the development of ICP in predisposed pregnant women.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is a common liver disorder, mostly occurring in the third trimester. ICP is defined as an elevation of serum bile acids, typically accompanied by pruritus and elevated activities of liver aminotransferases. ICP is caused by impaired biliary lipid secretion, in which endogenous steroids may play a key role. Although ICP is benign for the pregnant woman, it may be harmful for the fetus. We evaluated the differences between maternal circulating steroids measured by RIA (17-hydroxypregnenolone and its sulfate, 17-hydroxyprogesterone, and cortisol) and GC-MS (additional steroids), hepatic aminotransferases and bilirubin in women with ICP (n = 15, total bile acids (TBA) >8 μM) and corresponding controls (n = 17). An age-adjusted linear model, receiver-operating characteristics (ROC), and multivariate regression (a method of orthogonal projections to latent structure, OPLS) were used for data evaluation. While aminotransferases, conjugates of pregnanediols, 17-hydroxypregnenolone and 5β-androstane-3α,17β-diol were higher in ICP patients, 20α-dihydropregnenolone, 16α-hydroxy-steroids, sulfated 17-oxo-C19-steroids, and 5β-reduced steroids were lower. The OPLS model including steroids measured by GC-MS and RIA showed 93.3% sensitivity and 100% specificity, while the model including steroids measured by GC-MS in a single sample aliquot showed 93.3% sensitivity and 94.1% specificity. A composite index including ratios of sulfated 3α/β-hydroxy-5α/β-androstane-17-ones to conjugated 5α/β-pregnane-3α/β, 20α-diols discriminated with 93.3% specificity and 81.3% sensitivity (ROC analysis). These new data demonstrating altered steroidogenesis in ICP patients offer more detailed pathophysiological insights into the role of steroids in the development of ICP.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is the most common liver disorder of pregnancy. Diagnosis is based on the clinical picture, particularly the presence of pruritus with a deterioration of liver function tests, and typically elevated serum levels of total bile acids. ICP manifests in the second half of pregnancy, predominantly during the third trimester. Symptoms of the disease resolve spontaneously after delivery. Etiology is still not fully understood. Genetic defects in specific transport proteins, elevated levels of sex hormones, and various environmental factors are thought to play a role in the development of this disorder. Although practically benign for the pregnant woman, ICP represents a serious threat to the fetus. It increases the risk of preterm delivery, meconium excretion into the amniotic fluid, respiratory distress syndrome, and sudden intrauterine fetal death. Identifying fetuses at risk of ICP complications remains challenging. The ideal obstetrical management of ICP needs to be definitively determined. The aim of this review is to summarize the current knowledge on fetal complications of ICP and describe management options for their prevention.
