Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a metabolic and reproductive disorder. Current research findings present conflicting views on the effects of different PCOS phenotypes on outcomes in pregnancy and for newborns. METHODS This research study followed the guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). A thorough search of literature was carried out using the Cochrane Menstrual Disorders and Subfertility Group trials register, Web of Science, and EMBASE databases from their start to December 2023. The search focused on studies examining the links between hyperandrogenic and non-hyperandrogenic PCOS phenotypes and risks in pregnancy and neonatology. Odds ratios (ORs) and 95% confidence intervals (CIs) were computed using either a fixed-effects or random-effects model. RESULTS Our analysis incorporated 10 research studies. Expectant mothers with a hyperandrogenic PCOS subtype had increased ORs for gestational diabetes mellitus (GDM) and preeclampsia (PE) compared to those with a non-hyperandrogenic PCOS subtype, with respective values of 2.14 (95% CI, 1.18-3.88, I2 = 0%) and 2.04 (95% CI, 1.02-4.08, I2 = 53%). Nevertheless, no notable differences were detected in ORs for outcomes like preterm birth, live birth, miscarriage, cesarean delivery, pregnancy-induced hypertension, small for gestational age babies, large for gestational age newborns, and neonatal intensive care unit admissions between pregnant women with hyperandrogenic PCOS phenotype and those without. CONCLUSIONS This meta-analysis highlights that the presence of hyperandrogenism heightens the risks of GDM and PE within the PCOS population. Healthcare providers ought to be aware of this connection for improved patient management.

Abstract
Preeclampsia increases the risk of pregnancy-related complications, nevertheless a successful spiral vessel remodeling, and trophoblast invasion reduces disorders of pregnancy. Matrix metalloproteinase-2 (MMP-2) clears the path for trophoblast invasion, and activation of MMP-2 largely depends on extracellular matrix metalloproteinases inducer (EMMPRIN) protein. This study aimed to investigate EMMPRIN gene polymorphism and MMP-2 activity in preeclampsia patients. Archival whole blood and serum samples of 74 preeclampsia and 66 normotensive pregnant women age-matched were used in this case-control study. Genomic DNA was extracted from the whole blood samples and EMMPRIN gene amplified with specific primers following fragments sequence mutation analysis. Serum MMP-2 activity was determined using enzyme-linked immunosorbent assay (ELISA) and socio-demographic data of participants retrieved from the database. Age of preeclampsia patients (32.78 ± 6.39) years and body mass index (BMI) (33.09 ± 7.27) kg/m2 compared with the normotensive counterparts (32.33 ± 5.56) years and (32.33 ± 5.56) kg/m2,respectively, were not statistically significant (P > 0.05). Serum matrix metalloprotease-2 (MMP-2) activity was significantly reduced in preeclampsia group (16.34 ± 7.07) compared with the normotensives (25.63 ± 4.56) (P < 0.001), and rs424243T/G variant (55.6%) was overrepresented among the cases compared with the normotensives (16.7%). The single-nucleotide polymorphism T/G was found to be associated with preeclampsia (odds ratio [OR] = 7.63; 95% confidence interval [CI] = 3.95-14.75; P < 0.0001). Decreased activity of MMP-2 and rs424243T/G SNP of EMMPRIN gene was reported in preeclampsia. These preliminary data warrant a further investigation into the relationship between EMMPRIN gene polymorphism and MMP-2 activity in preeclampsia.

Magnetic blood purification-based soluble fms-like tyrosine kinase-1 removal in comparison with dextran sulfate apheresis and therapeutic plasma exchange. Artif Organs 2023; 47:1309-1318.

Abstract
BACKGROUND Preeclampsia remains one of the most serious complications of pregnancy. Effective therapies are yet to be developed. Recent research has identified an imbalance of angiogenic and antiangiogenic factors as a root cause of preeclampsia. In particular, soluble fms-like tyrosine kinase-1 (sFlt-1) has been shown to bind the angiogenic factors vascular endothelial growth factor (VEGF) and placental growth factor (PlGF), reducing blood vessel growth. Increasing preclinical and clinical evidence suggests that removal of the sFlt-1 protein may benefit patients with early onset preeclampsia. sFlt-1 may be removed by conventional blood purification techniques, such as therapeutic plasma exchange (TPE) and dextran sulfate apheresis (DSA), or emerging technologies, including extracorporeal magnetic blood purification (MBP). METHODS We compare the performance and selectivity of TPE, DSA, and MBP for the therapeutic removal of sFlt-1. For MPB, we employ magnetic nanoparticles functionalized with either sFlt-1 antibodies or the sFlt-1-binding partner, vascular endothelial growth factor (VEGF). RESULTS We demonstrate that sFlt-1 removal by MBP is feasible and significantly more selective than TPE and DSA at comparable sFlt-1 removal efficiencies (MBP 96%, TPE 92%, DSA 78%). During both TPE and DSA, complement factors (incl. C3c and C4) are depleted to a considerable extent (-90% for TPE, -55% for DSA), while in MBP, complement factor concentrations remain unaltered. We further demonstrate that the removal efficacy of sFlt-1 in the MBP approach is strongly dependent on the nanoparticle type and dose and can be optimized to reach clinically feasible throughputs. CONCLUSIONS Taken together, the highly selective removal of sFlt-1 and potential other disease-causing factors by extracorporeal magnetic blood purification may offer new prospects for preeclamptic patients.

Abstract
Background Preeclampsia is a pregnancy-related condition that causes high blood pressure and proteinuria after 20 weeks of pregnancy. It is linked to increased maternal mortality, organ malfunction, and foetal development limitation. In this view, there is a need critical to identify biomarkers for the early detection of preeclampsia. The objective of this study is to discover critical genes and explore medications for preeclampsia treatment that may influence these genes. Methods Four datasets, including GSE10588, GSE25906, GSE48424 and GSE60438 were retrieved from the Gene Expression Omnibus database. The GSE10588, GSE25906, and GSE48424 datasets were then removed the batch effect using the “sva” R package and merged into a complete dataset. The differentially expressed genes (DEGs) were identified using the “limma” R package. The potential small-molecule agents for the treatment of PE was further screened using the Connective Map (CMAP) drug database based on the DEGs. Further, Weight gene Co-expression network (WGNCA) analysis was performed to identified gene module associated with preeclampsia, hub genes were then identified using the logistic regression analysis. Finally, the immune cell infiltration level of genes was evaluated through the single sample gene set enrichment analysis (ssGSEA). Results A total of 681 DEGs (376 down-regulated and 305 up-regulated genes) were identified between normal and preeclampsia samples. Then, Dexamethasone, Prednisone, Rimexolone, Piretanide, Trazodone, Buflomedil, Scoulerin, Irinotecan, and Camptothecin drugs were screened based on these DEGs through the CMAP database. Two modules including yellow and brown modules were the most associated with disease through the WGCNA analysis. KEGG analysis revealed that the chemokine signaling pathway, Th1 and Th2 cell differentiation, B cell receptor signalling pathway and oxytocin signalling pathway were significantly enriched in these modules. Moreover, two key genes, PLEK and LEP were evaluated using the univariate and multivariate logistic regression analysis from the hub modules. These two genes were further validated in the external validation cohort GSE60438 and qRT-PCR experiment. Finally, we evaluated the relationship between immune cell and two genes. Conclusion In conclusion, the present study investigated key genes associated with PE pathogenesis that may contribute to identifying potential biomarkers, therapeutic agents and developing personalized treatment for PE.

Abstract
During pregnancy, complicated connections are formed between a mother and a fetus. In a successful pregnancy, the maternal-fetal interface is affected by dynamic changes, and the fetus is protected against the mother's immune system. Natural killer (NK) cells are one of the immune system cells in the female reproductive system that play an essential role in the physiology of pregnancy. NK cells not only exist in peripheral blood (PB) but also can exist in the decidua. Studies have suggested multiple roles for these cells, including decidualization, control of trophoblast growth and invasion, embryo acceptance and maintenance by the mother, and facilitation of placental development during pregnancy. Natural killer T (NKT) cells are another group of NK cells that play a crucial role in the maintenance of pregnancy and regulation of the immune system during pregnancy. Studies show that NK and NKT cells are not only effective in maintaining pregnancy but also can be involved in infertility-related diseases. This review focuses on NK and NKT cells biology and provides a detailed description of the functions of these cells in implantation, placentation, and immune tolerance during pregnancy and their role in pregnancy complications.

Abstract
Background: Nowadays, frozen-thawed embryo transfer (FET) cycles represent a high proportion of fertility treatments worldwide. Recent studies suggest differences in pregnancy outcomes depending on the FET treatment protocol used. The reason for this is still unclear, but the number of corpora lutea (CL) at conception is discussed as a possible factor. This study aims to investigate whether maternal and neonatal outcomes for pregnancies following FET lacking a CL differ from FET with one or more CL in order to explore a potential link between CL absence and adverse pregnancy outcomes. Methods: The study was designed as a retrospective, multi-center observational study with two cohorts after singleton live birth [0 CL cohort (FET in a programmed cycle, n = 114) and ≥ 1 CL cohort (FET in a natural or stimulated cycle, n = 68)]. Participants completed a questionnaire on the outcome of pregnancy and birth records were analyzed in a descriptive way. Multivariable logistic and linear regressions were performed in order to explore associations between CL absence and pregnancy outcomes. The strength of the agreement between the information in the survey and the diagnoses extracted from the files was assessed by Cohen's Kappa. Results: The risk of hypertensive disorders of pregnancy was higher after FET in the absence of a CL compared to FET with CL presence (aOR 5.56, 95% CI 1.12 – 27.72). Birthweights and birthweight percentiles were significantly higher in the 0 CL group. CL absence was a predictor of higher birthweight (adjusted coefficient B 179.74, 95% CI 13.03 – 346.44) and higher birthweight percentiles (adjusted coefficient B 10.23, 95%, 95% CI 2.28 – 18.40) particularly in female newborns of the 0 CL cohort. While the strength of the agreement between the reported information in the survey and the actual diagnoses extracted from the files was good for the majority of outcomes of interest it was fair in terms of hypertension (κ = 0.38). Conclusion: This study supports observations suggesting a potential link between a lack of CL at conception and adverse maternal and neonatal outcomes. Further investigations on causes and pathophysiological relationships are yet to be conducted.

Abstract
Altered placental development and function lead to placental diseases such as preeclampsia (PE) which is mainly characterized by insufficient trophoblast invasion and abnormally invasive placenta disorders. Long noncoding RNAs (lncRNAs) are widely reported to function as crucial players in the pathogenesis of PE. The present investigation clarified the role of lncRNA small nucleolar RNA host gene 16 (SNHG16) in PE. RT-qPCR was used to measure gene expression. The proliferation of trophoblast cells was examined using CCK-8 and EdU assays. Trophoblast migration and invasion were assessed using wound healing and transwell assays. The apoptosis was estimated by flow cytometry. Luciferase reporter and RNA pull-down assays were performed to explore the molecular mechanisms in trophoblast cells. We found that SNHG16 was downregulated in placenta from patients with PE. Moreover, SNHG16 depletion significantly inhibited trophoblast cell proliferation, migration, and invasion and stimulated apoptosis, while SNHG16 overexpression exerted an opposite effect. Subsequently, we confirmed that SNHG16 acted as a competing RNA (ceRNA) of miR-218-5p that was verified to directly target LASP1. Both miR-218-5p depletion and LASP1 upregulation antagonized the effect of SNHG16 knockdown on HTR-8/SVneo cell functions. In conclusion, SNHG16 facilitates trophoblast cell migration and invasion by the miR-218-5p/LASP1 axis.

Abstract
The aim of this study was to reveal the effects of anaesthesia strategies on maternal mean arterial pressure (MAP), heart rate, vasopressor consumption, adverse events, and neonatal resuscitation when women with preeclampsia (PE) undergo caesarean section (CS). Three major databases were searched for randomized controlled trials (RCTs) and prospective controlled studies (PCSs). Two authors independently screened, extracted, and checked eligibility and outcome data. Outcomes involved MAP, vasopressor use, maternal adverse events, APGAR scores, and neonatal resuscitation. Pooled estimates were carried out by contrast-based network meta-analysis, and pooled effect sizes were presented with 95% confidence interval (CI). Eleven RCTs and one PCS (n = 782) formed three-node network meta-analysis, and non-significant differences were observed in MAP, 5-min APGAR score, and neonatal intubation rate among the three anaesthesia strategies. General anaesthesia had significantly lower vasopressor consumption than spinal anaesthesia did (standardised mean difference = - 1.19, 95% confidence interval [CI]: - 1.76 to - 0.63), but it had higher maternal adverse event rate (risk ratio = 2.00, 95% CI 1.16-3.47). Because no optimal anaesthesia strategy has been shown to achieve a balanced maternal and neonatal outcome, therefore a shared decision-making process may be required regarding the most suitable choice of anaesthetic strategy for individual preeclamptic mother undergoing CS. Future larger studies may need to focus on evaluating the role of vasopressors on maternal hemodynamic as well as factors affecting maternal outcomes for different anaesthetic techniques in preeclamptic women undergoing CS.

Abstract
Preeclampsia (PE) is a complex pregnancy syndrome. Convincing evidence indicates that long non-coding RNAs (lncRNAs) are involved in the pathogenesis of PE. This research mainly investigated the mechanism of family with sequence similarity 99 member A (FAM99A) in PE. The expressions of FAM99A, miR-134-5p, and YAP1 were detected by quantitative real-time polymerase chain reaction (qRT-PCR). Cell apoptosis, migration, and invasion were detected by flow cytometry or transwell assay. The interaction between miR-134-5p and FAM99A or YAP1 was confirmed by dual-luciferase reporter assay. The protein expression of YAP1 was determined by western blot assay. FAM99A and YAP1 were significantly up-regulated, and miR-134-5p was significantly down-regulated in PE tissues (n=30). miR-134-5p was verified as a candidate of FAM99A and YAP1. FAM99A promoted cell metastasis, but reduced apoptosis in HTR8/SVneo cells by regulating miR-134-5p. miR-134-5p down-regulated YAP1 expression to suppress cell metastasis, while it induced apoptosis in HTR8/SVneo cells. FAM99A positively modulated YAP1 expression by sponging miR-134-5p. FAM99A modulated YAP1 to accelerate cell migration and invasion, and inhibited cell apoptosis in PE cells by sponging miR-134-5p. The novel regulatory network may shed light on the pathogenesis of PE.

miR-126a-3p induces proliferation, migration and invasion of trophoblast cells in pre-eclampsia-like rats by inhibiting A Disintegrin and Metalloprotease 9. Biosci Rep 2020; 39:221380.

Abstract
The present study aimed to investigate the underlying mechanism of miR-126a-3p in the proliferation, migration and invasion of trophoblast cells in pre-eclampsia-like rats by targeting A Disintegrin and Metalloprotease 9 (ADAM9). First, the interaction between miR-126a-3p and ADAM9 was confirmed via biochemical assays. Placental tissues and trophoblast cells were then obtained. RNA in situ hybridization was performed in order to detect miR-126a-3p expression in the placenta. Subsequently, a series of biological assays, including reverse transcription-quantitative PCR (RT-qPCR), Western blotting, MTT assay, apoptosis assay, cell cycle assay, wound healing assay and transwell assay were adopted in order to determine the cell proliferation, cell cycle distribution, apoptotic rate, and migration and invasion of trophoblast cells in each group. The results revealed that miR-126a-3p was down-regulated in the placenta of pre-eclampsia-like rats. In vivo experiments’ results indicated that miR-126a-3p could inhibit ADAM9 expression, and induce cyclin D1, Matrix metalloproteinase (MMP) 2 (MMP-2), MMP-9 expression. MTT, apoptosis and cell cycle assay results revealed that trophoblast cells transfected with miR-126a-3p mimic or si-ADAM9 exhibited higher proliferative activity and a lower apoptotic rate compared with the blank group (all P<0.05). The wound healing assay and transwell assay results confirmed that, compared with the blank group, the migration and invasion ability of trophoblast cells in the miR-126a-3p mimic group and small interfering RNA (siRNA)-ADAM9 group were significantly increased (all P<0.05). Conversely, miR-126a-3p inhibitor treatment revealed the opposite effect (all P<0.05). In conclusion, the present study demonstrated that miR-126a-3p could enhance proliferation, migration and invasion, but decrease the apoptosis rate of trophoblast cells in pre-eclampsia-like rats through targeting ADAM9.

Abstract
Preeclampsia has impacted 3-5% pregnancies among the world and its complications lead to both maternal and fetal morbidity and mortality. However, management of preeclampsia is limited. Nanoparticles targeting chondroitin sulfate A (CSA) can deliver drugs to placenta. Inactivation of soluble fms-like tyrosine kinase (sFlt-1) and nuclear factor-erythroid 2-like 2 (Nrf2) has been proved to alleviate preeclampsia and improve maternal and fetal outcomes. Carboxyl-polyethylene glycol-poly (d,l-lactide) (COOH-PEG5K-PLA8K), cationic lipid DOTAP, and siNrf2 and sisFlt-1 were used to construct the nanoparticles and conjugating peptides targeting CSA was fabricated to it. The expression levels of proteins and RNAs were estimated by qRT-PCR and Western blot assays. ELISA assays were performed to evaluate levels of circulating sFlt-1. The nanoparticles containing siNrf2 and sisFlt-1 are targeted to the placenta trophoblasts and downregulated the expression levels of Nrf2 and sFlt-1 as well as their downstream genes in the placental cells of model mice. Treatment of nanoparticles induced the expression of angiogenic factors in placenta. Knocking down Nrf2 and sFlt-1 synchronously alleviated the preeclampsia and increased the maternal and fetal outcomes in preeclampsia model mice. Nanoparticle-mediated simultaneous downregulation of placental Nrf2 and sFlt1 improved maternal and fetal outcomes in a preeclampsia mouse model.

Abstract
Preeclampsia is a serious pregnancy-induced disorder unique to humans. The etiology of preeclampsia is poorly understood; however, poor placental formation is thought causal. Galectin-7 is produced by trophoblast and is elevated in first-trimester serum of women who subsequently develop preeclampsia. We hypothesized that elevated placental galectin-7 may be causative of preeclampsia. Here, we demonstrated increased galectin-7 production in chorionic villous samples from women who subsequently develop preterm preeclampsia compared with uncomplicated pregnancies. In vitro, galectin-7 impaired human first-trimester trophoblast outgrowth, increased placental production of the antiangiogenic sFlt-1 splice variant, sFlt-1-e15a, and reduced placental production and secretion of ADAM12 (a disintegrin and metalloproteinase12) and angiotensinogen. In vivo, galectin-7 administration (E8-E12) to pregnant mice caused elevated systolic blood pressure, albuminuria, impaired placentation (reduced labyrinth vascular branching, impaired decidual spiral artery remodeling, and a proinflammatory placental state demonstrated by elevated IL1β, IL6 and reduced IL10), and dysregulated expression of renin-angiotensin system components in the placenta, decidua, and kidney, including angiotensinogen, prorenin, and the angiotensin II type 1 receptor. Collectively, this study demonstrates that elevated galectin-7 during placental formation contributes to abnormal placentation and suggests that it leads to the development of preeclampsia via altering placental production of sFlt-1 and renin-angiotensin system components. Targeting galectin-7 may be a new treatment option for preeclampsia.

Abstract
Background This study aimed to compare serum levels of vascular endothelial growth factor (VEGF) and the VEGF receptors, VEGFR-1 and VEGFR-2, free placental growth factor (fPGF), endostatin, and serum pregnancy-associated plasma protein-A (PAPP-A) levels in women with mild and severe preeclampsia and healthy pregnant women. Material/Methods A included patients diagnosed with mild preeclampsia (n=32), severe preeclampsia (n=32), and healthy pregnant women (n=24). Serum levels of VEGF-A, VEGFR-1, VEGFR-2, fPGF, endostatin, and PAPP-A levels were measured by enzyme-linked immunosorbent assay (ELISA). Results In women with mild and severe preeclampsia, the gestation age at birth and birth weight were found to be significantly lower than the control group (p<0.001). Serum levels of endostatin, VEGFR-1, and VEGF-A levels were significantly increased in pregnant women with preeclampsia compared with healthy pregnant women (p<0.001). Serum levels of PAPP-A, VEGFR-2, and fPGF were significantly higher in healthy pregnant women when compared with women with preeclampsia (p=0.024, p<0.001, and p<0.001, respectively), but there were no significant differences between women with mild and severe preeclampsia. Conclusions Reduced serum levels of the angiogenic factors PAPP-A, VEGFR-2, and fPGF distinguished between women with preeclampsia and normotensive pregnant women but did not significantly distinguish between mild and severe preeclampsia.

Abstract
Preeclampsia is a complication of pregnancy characterized by new-onset hypertension and proteinuria of gestation, with serious consequences for mother and infant. Although a vast amount of research has been performed on the pathogenesis of preeclampsia, the underlying mechanisms of this multisystemic disease have remained to be fully elucidated. Data were retrieved from Gene Expression Omnibus database GSE40182 dataset. After data preprocessing, differentially expressed genes of placental cells cultured in vitro from preeclampsia and normal pregnancy were determined and subjected to Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis to identify the associated pathways. Furthermore, functional principal component analysis (FPCA) was used to calculate the corresponding F-value of each gene. In order to further study the key signaling pathways of preeclampsia, an elastic-net regression model and the Mann-Whitney U (MWU) test were used to estimate the weight of the signaling pathways. Finally, a co-expression network was generated and hub genes were identified based on the topological features. A total of 134 pathways with a role in preeclampsia were identified. The gene expression data of placenta cells cultured in vitro for different durations were determined and F-values of genes were estimated using the FPCA model. The top 1,000 genes were identified as the differentially expressed genes and subjected to further analysis by elastic-net regression and MWU test. Two key signaling pathways were different between the preeclampsia and control groups, namely hsa05142 Chagas disease and hsa05204 Chemical carcinogenesis. Among the genes involved in these two key pathways, 13 hub genes were identified from the co-expression network. Clustering analysis demonstrated that depending on these hub genes, it was possible to divide the sample into four distinct groups based on different incubation time. The top 3 candidates were Toll-like receptor 2 (TLR2), glutathione S-transferase omega 1 (GSTO1) and mitogen-activated protein kinase 13 (MAPK13). TLR2 and associated pathways are known to be closely associated with preeclampsia, indirectly demonstrating the applicability of the analytic process applied. However, the role of GSTO1 and MAPK13 in preeclampsia has remained poorly investigated, and elucidation thereof may be a worthwhile endeavor. The present study may provide a basis for exploring potential novel genes and pathways as therapeutic targets for preeclampsia.

Abstract
Pre-eclampsia (PE) is a leading cause of maternal and perinatal morbidity and mortality but the exact underlying mechanisms of PE pathogenesis remain elusive. Accumulated data suggested that the long noncoding RNAs (lncRNAs) play important roles in the pathogenesis of PE. The present study identified the changes of lncRNA Linc00261 in PE and its effects on trophoblasts invasion and migration. Our results showed that the expression of Linc00261 was upregulated in placental tissues of PE women compared with those of healthy pregnant women. Overexpression of Linc00261 suppressed cell invasion and migration, induced cell apoptosis, and caused cell-cycle arrest at G0 /G1 phase of HTR-8/SVneo cells; while knockdown of Linc00261 had the opposite effects on the HTR-8/SVneo cells. Mechanistic studies showed Linc00261 functioned as a competing endogenous RNA for miR-558 in HTR-8/SVneo cells, and miR-558 was negatively regulated by Linc00261. The expression level of miR-558 in the PE group was significantly lower than the control group, and the expression level of Linc00261 was negatively correlated with the expression level of miR-558 in the placental tissues of women with PE. Furthermore, miR-558 was found to negatively regulate the expression of TIMP metallopeptidase inhibitor 4 (TIMP4) via targeting the 3' untranslated region in the HTR-8/SVneo cells. Overexpression of miR-558 increased HTR-8/SVneo cell invasion and migration, which was attenuated by TIMP4 overexpression. More importantly, both overexpression of miR-558 and knockdown of TIMP4 partially reversed the suppressive effects of Linc00261 overexpression on cell invasion and migration of HTR-8/SVneo cells. Collectively, our results for the first time showed the upregulation of Linc00261 in the placental tissues of severe PE patients. The mechanistic results indicated that Linc00261 exerted the suppressive effects on the trophoblast invasion and migration via targeting miR-558/TIMP4 axis, which may involve in the pathogenesis of PE.

Abstract
Pre‐eclampsia is associated with inadequate placental blood flow and placental ischaemia. Placental vascular tone is essential for maintaining adequate placental blood flow. Oxytocin is increased in placental system at late pregnancy and onset of labour, and presented strongly concentration‐dependent contractions in placental vascular, suggesting that oxytocin could be involved in regulating placental vascular tone and circulation. However, information about the reactivity of oxytocin in pre‐eclamptic placental vasculature is limited. This study used a large number of human placentas to reveal the pathophysiological changes and its underlying mechanisms of oxytocin‐induced vasoconstrictions in placental vessels under pre‐eclamptic condition. Present study found that oxytocin‐induced contractions were significantly decreased in human pre‐eclamptic placental vasculature, associated with a deactivated transcription of oxytocin receptor gene. The deactivated oxytocin receptor gene transcription was ascribed to a relatively higher DNA methylation status of CpG islands in oxytocin receptor gene promoter. This study was first to reveal that a hyper‐methylation of CpG islands in oxytocin receptor gene promoter, leading to a relatively low pattern of oxytocin receptor expression, was responsible for the decreased sensitivity of oxytocin in pre‐eclamptic placental vessels.

Abstract
We analyzed diurnal hemodynamic parameters (HR, systolic BP, and diastolic BP) recorded from two groups of edematous and preeclamptic pregnant women. The unidirectional character of changes in the control over the functional state of cardiovascular system was revealed except for the indices, which mark a pathological process: elevated diurnal BP in preeclampsia and diminished percentage of oscillation power in edematous patients. Uniformity of the regulatory changes in patients with and without arterial hypertension can be viewed as manifestation of allostasis developed by the cardiovascular system during pregnancy. In preeclampsia, the greater allostatic load was reflected by the changes in diurnal, daytime, and nighttime BP and in the circadian index calculated for HR, systolic BP, and diastolic BP. In edematous patients, elevation of allostatic load was indicated by the percentage of ultradian rhythms.

Abstract
PURPOSE OF REVIEW Preeclampsia (PE) is a hypertensive disorder exclusive for pregnancy. It affects women all over the world and poses a great threat to life, both for mother and child. No definitive treatment exists and placenta delivery comprises the only known cure for PE. One of the most severe complications observed in preeclamptic women is the occurrence of cardiovascular diseases (CVDs) later in life. RECENT FINDINGS Both PE and CVDs share some of their pathogenic pathways and gene variations. Thus far, a number of publications have examined those relationships; however, almost all of them focus only on common risk factors. The precise pathomechanism and genetic basis of PE and its associated cardiovascular complications remain unknown. Therefore, the aim of this review is to unify and clarify the current state of knowledge and provide direction for future studies, especially those regarding the genetic aspect.

Abstract
In pregnancy, there are numerous changes which occur to accommodate the needs of both the fetus and placenta. These changes present us with a unique set of clinical challenges particularly in the setting of any disease processes occurring during pregnancy. It is essential to understand that the systems profoundly affected are the cardiovascular and renal systems. The most predominant disease process occurring in pregnancy affecting both the cardiovascular and renal system is the spectrum of hypertensive disorders specifically pre-eclampsia. Due to its high incidence worldwide, it is considered as the most common cause of infant and maternal morbidity and mortality. While the international definition, classification scheme and diagnostic criteria for Hypertensive Disorders of Pregnancy still must be agreed upon, hypertension has been the mandatory feature for all established guidelines. Pre-eclampsia particularly the severe form which is recognized as HELLP (Hemolysis, Elevated Liver enzymes and Low Platelet count) syndrome is the primary cause of acute kidney injury in pregnancy. In this review, we would primarily discuss the hemodynamic and vascular changes, anatomical and physiologic renal adaptations occurring during normal pregnancy and the complications which arise in the setting of hypertensive diseases. Mainly focusing on the pre-eclampsia spectrum, since knowledge of these is of clinical importance not only in understanding its role in the disease process but more so its implications for prevention, screening, diagnosis, and management.

Association between duration of intravenous antibiotic administration and early-life microbiota development in late-preterm infants. Eur J Clin Microbiol Infect Dis 2018; 37:475-483.

Abstract
Antibiotic treatment is common practice in the neonatal ward for the prevention and treatment of sepsis, which is one of the leading causes of mortality and morbidity in preterm infants. Although the effect of antibiotic treatment on microbiota development is well recognised, little attention has been paid to treatment duration. We studied the effect of short and long intravenous antibiotic administration on intestinal microbiota development in preterm infants. Faecal samples from 15 preterm infants (35 ± 1 weeks gestation and 2871 ± 260 g birth weight) exposed to no, short (≤ 3 days) or long (≥ 5 days) treatment with amoxicillin/ceftazidime were collected during the first six postnatal weeks. Microbiota composition was determined through 16S rRNA gene sequencing and by quantitative polymerase chain reaction (qPCR). Short and long antibiotic treat ment significantly lowered the abundance of Bifidobacterium right after treatment (p = 0.027) till postnatal week three (p = 0.028). Long treatment caused Bifidobacterium abundance to remain decreased till postnatal week six (p = 0.009). Antibiotic treatment was effective against members of the Enterobacteriaceae family, but allowed Enterococcus to thrive and remain dominant for up to two weeks after antibiotic treatment discontinuation. Community richness and diversity were not affected by antibiotic treatment, but were positively associated with postnatal age (p < 0.023) and with abundance of Bifidobacterium (p = 0.003). Intravenous antibiotic administration during the first postnatal week greatly affects the infant's gastrointestinal microbiota. However, quick antibiotic treatment cessation allows for its recovery. Disturbances in microbiota development caused by short and, more extensively, by long antibiotic treatment could affect healthy development of the infant via interference with maturation of the immune system and gastrointestinal tract.

Abstract
Context: It is a well-known fact that severe pregnancy-induced hypertension (PIH) can be disastrous at times as it can cause a lot of complications to both pregnant women and her baby. Hence, it is always desirable to know the extent of severity by a real-time and easily accessible modality like ultrasound. Aims: The aim of the study was to evaluate the incidence of raised intracranial pressure (ICP) in severe preeclampsia and eclampsia patients using ocular ultrasonography with optic nerve sheath diameter (ONSD) measurement. Settings and Design: This study design was a prospective and clinically controlled blinded observational study. Materials and Methods: After taking necessary permissions from the Institution Ethical Committee, 75 patients were enrolled for the study. However, finally, 25 patients in severe preeclampsia and 24 in eclampsia group were compared with 25 normal term antenatal women. Demographic profiles, hemodynamic parameters, laboratory markers for severity of PIH, and ultrasonographic OSND were measured. Statistical Analysis Used: They were statistically analyzed and compared using one-way ANOVA and Tukey's test. Value of P < 0.05 was considered statistically significant. Results: All the three groups were comparable in terms of age, body weight, gestation age, gestity, and the number of primigravida in each group. There was a significant difference (P < 0.05) in mean levels of hepatic aminotransferase levels and platelet counts between groups. Aspartate transaminase and alanine transaminase levels were much higher in Group II and III as compared to Group I, while platelet levels were lower in study groups indicating increase in severity of PIH. There was also a significant difference for systolic blood pressure and diastolic blood pressure (P < 0.001) as both were significantly higher in study groups. Among severe PIH groups (Group II and III), the difference was comparable. Conclusions: OSND is a surrogate marker for raised ICP in severe PIH patients. It is a rapid, bedside, noninvasive, and readily accessible tool and could be a part of a holistic approach for managing such patients.
