Abstract
Pregnancy-induced hypertension (PIH) is a hypertensive disorder during pregnancy and can induce perinatal death of human infants. MicroRNA (miR)-195-5p was validated to display low expression in severe preeclampsia placentas, but the role of miR-195-5p in pregnancy-induced hypertension (PIH) has not been investigated. The study emphasized on the functions and mechanism of miR-195-5p in PIH. A reduced uterine perfusion pressure (RUPP) rat model was established to mimic PIH in vivo. Adenovirus (Ad)-miR-195-5p agomir and/or Ad-OTX1 were further injected into some model rats. RT-qPCR was conducted to assess the expression of miR-195-5p and orthodenticle homeobox 1 (OTX1) in rat placental tissues, the isolated aortic endothelial cells (AECs), and in serum samples of PIH patients. Western blot analysis was implemented to measure the protein levels of OTX1, VEGFA, and key factors involved in the MAPK signaling pathway. The concentrations of oxidative stress markers (superoxide dismutase, catalase, and lipid hydroperoxide) in AECs and placental tissues of RUPP rats were measured by corresponding kits. The binding relation between miR-195-5p and OTX1 was verified using the dual-luciferase reporter assay. Hematoxylin-eosin staining was conducted to evaluate the pathological features of rat placental tissues. MiR-195-5p was downregulated, while OTX1 was upregulated in rat placental tissues and human serum samples of PIH patients. MiR-195-5p could target OTX1 and inversely regulate OTX1 expression in AECs and rat placental tissues. In addition, miR-195-5p can negatively regulate VEGFA level. Furthermore, miR-195-5p inactivates oxidative stress and the MAPK signaling by downregulating OTX1 in AECs. In vivo experiments revealed that OTX1 overexpression reversed the protective effect of miR-195-5p overexpression on placental damage and oxidative stress. MiR-195-5p alleviates PIH by inhibiting oxidative stress via targeting OTX1 and inactivating MAPK signaling.

Abstract
BACKGROUND Hypertensive disorders in pregnancy (HDPs) are the leading causes of maternal and perinatal death worldwide, and appropriate prenatal care is beneficial toward improve pregnancy outcomes in populations at high risk of preeclampsia. OBJECTIVE To describe variations in regional manifestations and outcomes of HDPs among the Chinese population to aid in the development of region-specific perinatal management guidelines. METHODS This is a retrospective study. The clinical data of patients with HDP in 3 different regions were collected to explore the characteristics of HDP patients in different regions of China. RESULTS In Peking University First Hospital, a regional rescue center for prenatal care and delivery, the proportion of patients with high-risk factors for PE was considerably high; 37.8% were of advanced maternal age, and 14.7% were obese. Among the patients, at this hospital, the proportion of comorbidities (e.g., chronic hypertension) in HDP patients was higher than that in the other 2 specialized maternal and child health care hospitals. CONCLUSION Targeted prenatal care procedures should be established based on regional characteristics to improve the quality of perinatal health care and reduce the incidence of HDP.

Abstract
BACKGROUND Routine health facility data provides the opportunity to monitor progress in quality and uptake of health care continuously. Our study aimed to assess the reliability and usefulness of emergency obstetric care data including temporal and regional variations over the past five years in Tanzania Mainland. METHODS Data were compiled from the routine monthly district reports compiled as part of the health management information systems for 2016-2020. Key indicators for maternal and neonatal care coverage, emergency obstetric and neonatal complications, and interventions indicators were computed. Assessment on reliability and consistency of reports was conducted and compared with annual rates and proportions over time, across the 26 regions in of Tanzania Mainland and by institutional delivery coverage. RESULTS Facility reporting was near complete with 98% in 2018-2020. Estimated population coverage of institutional births increased by 10% points from 71.2% to 2016 to 81.7% in 2020 in Tanzania Mainland, driven by increased use of dispensaries and health centres compared to hospitals. This trend was more pronounced in regions with lower institutional birth rates. The Caesarean section rate remained stable at around 10% of institutional births. Trends in the occurrence of complications such as antepartum haemorrhage, premature rupture of membranes, pre-eclampsia, eclampsia or post-partum bleeding were consistent over time but at low levels (1% of institutional births). Prophylactic uterotonics were provided to nearly all births while curative uterotonics were reported to be used in less than 10% of post-partum bleeding and retained placenta cases. CONCLUSION Our results show a mixed picture in terms of usefulness of the District Health Information System(DHIS2) data. Key indicators of institutional delivery and Caesarean section rates were plausible and provide useful information on regional disparities and trends. However, obstetric complications and several interventions were underreported thus diminishing the usefulness of these data for monitoring. Further research is needed on why complications and interventions to address them are not documented reliably.

Abstract
PURPOSE OF REVIEW Hypertensive disorders of pregnancy remain a highly morbid condition that affects both the mother and fetus, complicate approximately 10% of pregnancies worldwide, and contribute to immediate and long-term cardiovascular outcomes. There is still much to learn regarding pathogenesis and treatment goals. RECENT FINDINGS There is updated information on the pathogenesis of preeclampsia and treatment thresholds for HTN in pregnancy. l-Kynurenine, a metabolite of the essential amino acid l-tryptophan, has been implicated in preeclampsia as decreased levels were found in a uninephrectomized pregnant mouse model of preeclampsia, where replacement of l-kynurenine rescued the preeclamptic state. Further, data from CHIPS (The Control of HTN in Pregnancy Study) and CHAP (Chronic HTN and Pregnancy) trials demonstrate not only the safety of lowering blood pressure to either a diastolic goal of 85 mmHg (CHIPS) or less than 160/105 mmHg (CHAP) without detriment to the fetus but the CHAPS trial has also shown a decrease in the rate of preeclampsia in the treatment group. SUMMARY We will summarize the different types of hypertensive disorders in pregnancy, updates on the pathogenesis of preeclampsia, and appropriate HTN management based on the latest evidence in order to better care for mother and child.

Abstract
Hypertension is a leading risk factor for cardiovascular disease in women. Both traditional and sex-specific risk modifiers occurring from menarche to pregnancy to menopause modulate the risk of hypertension and adverse cardiovascular events. This review provides a narrative summary of risk and treatment of hypertension in women across the lifespan, from adolescence to the post-menopausal period, where each period represents a potential window for risk assessment, diagnosis, and appropriate treatment. Management of hypertension throughout a woman's life must be included in a holistic cardiovascular prevention approach for women in order to prevent future cardiovascular complications.

Abstract
Magnesium is the fourth most common mineral in the human body and the second richest intracellular cation. This element is necessary for many physiological reactions, especially in the cardiovascular and respiratory systems. COVID-19 is an infectious disease caused by SARS-CoV-2. The majority of people who become ill as a result of COVID-19 have mild-to-moderate symptoms and recover without specific treatment. Moreover, there are people who develop severe forms of COVID-19, which require highly specialized medical assistance. Magnesium deficiency may play a role in the pathophysiology of infection with SARS-CoV-2. The primary manifestation of COVID-19 remains respiratory, but the virus can spread to other organs and tissues, complicating the clinical picture and culminating in multiorgan failure. The key mechanisms involved in the disease include direct viral cytotoxicity, endothelial dysfunction, and exaggerated release of inflammatory cytokines. The aim of this review was to summarize the available data regarding the role of magnesium in COVID-19 patients and its particularities in different clinical settings.

Abstract
Aims: To evaluate the efficacy of different pharmacologic treatment for severe hypertension during pregnancy. Methods: Two reviewers searched Ovid MEDLINE, Ovid EMbase, and the Cochrane Library for randomized clinical trials from the establishment of the database to 15 July 2021 that were eligible for inclusion and analyzed the pharmaceuticals used for severe hypertension in pregnancy. Results: 29 relevant trials with 2,521 participants were involved. Compared with diazoxide in rate of achieving target blood pressure, other pharmaceuticals, including epoprostenol (RR:1.58, 95%CI:1.01-2.47), hydralazine\dihydralazine (RR:1.57, 95%CI:1.07-2.31), ketanserin (RR:1.67, 95%CI:1.09-2.55), labetalol (RR:1.54, 95%CI:1.04-2.28), nifedipine (RR:1.54, 95%CI:1.04-2.29), and urapidil (RR:1.57, 95%CI:1.00-2.47), were statistically significant in the rate of achieving target blood pressure. According to the SUCRA, diazoxide showed the best therapeutic effect, followed by nicardipine, nifedipine, labetalol, and nitroglycerine. The three pharmaceuticals with the worst therapeutic effect were ketanserin, hydralazine, and urapidil. It is worth noting that the high ranking of the top two pharmaceuticals, including diazoxide and nicardipine, comes from extremely low sample sizes. Other outcomes were reported in the main text. Conclusion: This comprehensive network meta-analysis demonstrated that the nifedipine should be recommended as a strategy for blood pressure management in pregnant women with severe hypertension. Moreover, the conventional pharmaceuticals, including labetalol and hydralazine, showed limited efficacy. However, it was important to note that the instability of hydralazine reducing blood pressure and the high benefit of labetalol with high dosages intakes should also be of concern to clinicians.

Abstract
BACKGROUND To investigate the effects of down's screening markers and maternal characteristics on preeclampsia (PE) pregnancy outcome during early and middle pregnancy. METHODS A retrospective study of a cohort of 246 PE and 18,709 No-PE pregnant women who participated in Down's screening during early and middle pregnancy was performed. Clinical data of pregnancy-related were collected. Multivariate binary logistic regression was used to analyze the adjusted odds ratio (aOR) and 95% confidence interval (CI) of Down's screening markers, maternal characteristics, pregnancy outcome, and other related variables, and to evaluate the influencing factors of each indicator on PE. P < .05 was considered to be statistically significant. RESULTS Compared with the non-PE group, the concentration and median multiple (MoM) of pregnancy-associated plasma protein-A (PAPP-A) and free beta subunit of human chorionic gonadotropin (free β-hCG) in PE group were both lower (P < .001). Multivariate binary logistic regression analysis showed that low birth weight, hydronephrosis, premature delivery, fetal growth retardation, cesarean section, live birth, hyperlipemia, infection, decreased free β-hCG and first trimester maternal weight were risk factors for PE (aOR were: 7.552, 6.684, 4.154, 3.762, 3.612, 2.454, 1.757, 1.562, 1.270, and 1.077, respectively), while uterine scar, premature rupture of membranes and elevated PAPP-A were protective factors of PE (aOR were: 0.222, 0.328 and 0.612, respectively). CONCLUSION Decreased maternal serum PAPP-A level, increased free β-hCG, hyperlipemia, premature delivery, cesarean section, live birth, hydronephrosis, fetal growth retardation, low birth weight, and infection are risk factors for PE, while uterine scar and premature rupture of membrane are protective factors for PE.

Uterine Ultrasound Doppler Hemodynamics of Magnesium Sulfate Combined with Labetalol in the Treatment of Pregnancy-Induced Hypertension Using Empirical Wavelet Transform Algorithm. COMPUTATIONAL INTELLIGENCE AND NEUROSCIENCE 2022; 2022:7951342.

Abstract
The aim of this study was to explore the hemodynamic changes of magnesium sulfate combined with labetalol in the treatment of pregnancy-induced hypertension (PIH) under Doppler uterine ultrasound based on the empirical wavelet transform (EWT) algorithm. 500 patients with PIH in the hospital were selected and randomly divided into the control group (n = 250) and the observation group (n = 250). The control group was treated with conventional magnesium sulfate; the observation group was given labetalol based on magnesium sulfate drip in the control group. The uterine artery blood flow simulation model was established based on the EWT algorithm and compared with a short-time Fourier transform (STFT). The normalized root mean square error (NRMSE) of the STFT method was 0.19, and the NRMSE extracted by the EWT method was 0.13. After treatment, the blood pressure index, 24-hour urinary protein, and incidence of adverse birth outcomes in the observation group were lower than those in the control group; the effective rate of the control group (90.4%) was lower than that of the observation group (97.6%); the hemodynamic indexes of the uterine artery in the observation group were lower than those in the control group, and the differences were statistically significant (P < 0.05). The estimation accuracy of the EWT method was higher than that of the traditional STFT method; the combined treatment of magnesium sulfate and labetalol in patients with PIH had a remarkable effect, which could control the blood pressure index and reduce the 24-hour urinary protein; the uterine artery Doppler ultrasound examination could change hemodynamics and improve the adverse outcomes of mothers and infants.

Abstract
BACKGROUND Several studies have reported an association between perinatal complications and the severity of the hypertensive disease. The increasing number of pregnancies complicated by hypertension and the small assurance about the perinatal effects of hypertensive drug use during pregnancy involves the need of studying the better management of hypertensive mothers. OBJECTIVE To evaluate the association between maternal use of antihypertensive drugs and maternal and neonatal outcomes in women with chronic hypertension. STUDY DESIGN We conducted a population-based study including all deliveries of hypertensive women that occurred between 2007-2017 in the Lombardy region, Italy. We evaluated the risk of several maternal and neonatal outcomes among women who filled antihypertensive prescriptions within the 20th week of gestation. Propensity score stratification was used to account for key potential confounders. RESULTS Out of 5,553 pregnancies, 2,138 were exposed to antihypertensive treatment. With respect to no-users, users of antihypertensive drugs showed an increased risk of preeclampsia (RR:1.68, 95%CI:1.42-1.99), low birth weight (1.30,1.14-1.48), and preterm birth (1.25,1.11-1.42). These results were consistent in a range of sensitivity and subgroup analyses. CONCLUSION Early exposure to antihypertensive drugs in the first 20 weeks of gestation was associated with an increased risk of preeclampsia, low birth weight, and preterm birth.

Predicting Hypertensive Disease in the First Trimester of Pregnancy: Risk Models and Analysis of Serum D-dimer Levels Combined with Plasma Pregnancy-Associated Protein A, Free β-Subunit of Human Chorionic Gonadotropin, and Fetal Nuchal Translucency. BIOMED RESEARCH INTERNATIONAL 2022; 2022:8264958. [PMID: 35402610 PMCID: PMC8986391 DOI: 10.1155/2022/8264958] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Accepted: 03/05/2022] [Indexed: 11/18/2022]
Abstract
We aimed to investigate the predictive ability of serum levels of D-dimer (DD) in the first trimester for the occurrence of hypertensive disorders of pregnancy (HDP). In this retrospective, case-cohort study, we measured the levels of DD, plasma pregnancy-associated protein A (PAPP-A), and free β-subunit of human chorionic gonadotropin (free β-hCG) and analyzed fetal nuchal translucency (NT) in 150 healthy gravidas, 126 cases of gestational hypertension (GH), 53 cases of preeclampsia (PE), and 41 cases with severe preeclampsia (SPE). Likelihood ratio models and risk models were built using single markers (DD, PAPP-A, free β-hCG, and NT) and combinations of those markers. Analyses showed that the levels of DD multiple of the median (MoM) in the GH, PE, and SPE groups were all significantly higher than those in the control group, with significant differences between groups (χ2 = 70.325, P < 0.001). The area under curve (AUCs) for DD in the GH, PE, and SPE groups was 0.699, 0.784, and 0.893, respectively; the positive likelihood ratio (+LR) was 1.534, 1.804, and 2.941, respectively; and the negative likelihood ratio (-LR) was 0.022, 0.081, and 0, respectively. When the cut-off values of DD for the GH, PE, and SPE groups were 0.725, 0.815, and 0.945 MoM, respectively, the corresponding sensitivities were 0.992, 0.962, and 1.000, respectively. As gestational hypertension progressed, the levels of DD tended to increase gradually. The maternal serum level of DD in the first trimester had correlative and diagnostic value for HDP. The sensitivity and specificity of maternal serum levels of DD level in the first trimester for different types of HDP were significantly different; the best sensitivity and specificity were detected in the SPE group. First trimester DD level, combined with other biochemical markers, may improve our ability to diagnose HDP.

A risk model that combines MAP, PlGF, and PAPP-A in the first trimester of pregnancy to predict hypertensive disorders of pregnancy. J Hum Hypertens 2022; 36:184-191. [PMID: 33594246 DOI: 10.1038/s41371-021-00488-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 01/03/2021] [Accepted: 01/18/2021] [Indexed: 02/06/2023]
Abstract
Whether the first trimester maternal mean arterial pressure (MAP), placental growth factor (PlGF), and pregnancy-associated plasma protein A (PAPP-A) can predict hypertensive disorders of pregnancy (HDP) is unclear. We conducted a retrospective case-control study with the total population of 539 gravidas, of these 447 had normal pregnancy, 27 had gestational hypertension (GH), 36 had preeclampsia (PE), and 29 had preeclampsia with severe features (SPE). Prediction for HDP was determined by the area under curve (AUC). Compared to the healthy group, the multiple of the median (MoM) for MAP was increased in the study groups, while PlGF and PAPP-A were decreased. When the cutoff values for MAP, PlGF, and PAPP-A were 1.069, 0.769, and 0.673 MoM, respectively, the sensitivities for predicting HDP were 0.517, 0.446, and 0.500 and the specificities were 0.744, 0.826, and 0.769, respectively. To predict GH, the highest AUC was 0.755 (95% CI: 0.655-0.856, p < 0.001) based on MAP, PlGF, and PAPP-A. The combined PlGF and PAPP-A had the highest AUC (0.683 [95% CI: 0.584-0.782, p < 0.001] and 0.755 [95% CI: 0.682-0.829, p < 0.001]) for prediction of PE and SPE. We found that MAP, serum levels of PlGF, and PAPP-A in the first trimester pregnancy are markers that predict HDP in the third trimester. The combination of markers is far superior to single markers alone. To improve the diagnostic value, specific cutoff values should be applied to GH, PE, SPE in each condition.

Abstract
The research was aimed at analyzing the value of the optimized eXtreme Gradient Boosting (XGBoost) algorithm-based ultrasound cardiogram images in the diagnosis of pregnant hypertension patients. A total of 145 pregnant women (85 cases suffered from hypertension disease during pregnancy and 60 other normal women were healthy) were selected as the reference to the comparison and analysis of ultrasound cardiac function parameter, common carotid artery parameter, and the coupling relationship between hearts and cervical vessels of pregnant hypertension patients. The results demonstrated ultrasound cardiac function parameter of pregnant hypertension patients as follows. The maximum volume of the left atrium (LAVmax) was 35.65 mm, left ventricular end-systolic volume (LVESV) was 31.07 mm, and left ventricular end-diastolic volume (LVEDV) was 88.73 mm. All the above indexes were obviously higher than those of the normal control group (P < 0.05). Besides, intima-media thickness (IMT) of common carotid artery (465.84 μm), pulse wave velocity (PWV) (8.09 m/s), pressure of turning point 1 from isovolumic contraction phase to ejection phase (PT1) (126.5 mmHg), arterial enhancement pressure (AP) (6.14 mmHg), and arterial pressure enhancement index (8.58%) were all significantly higher than those of the normal control group (P < 0.05). In addition, the correlation between the coupling (E/A) of hearts and carotid artery of pregnant hypertension patients and PWV was not obvious (r = -0.08432, P > 0.05). The results of the research indicated that intima-media inside carotid artery of pregnant hypertension patients thickened obviously, and it became less elastic compared with that of normal healthy pregnant women. What is more, cardiac morphological changes were manifested mainly as the enlargement of the left atrial chamber and the thickening of the interventricular septum. Volume load and blood flow velocity both increased, and left ventricular diastolic function was damaged. XGBoost algorithm-based ultrasound cardiogram images could improve the diagnostic effects of hypertension during pregnancy effectively.

Front Med (Lausanne) 2021; 8:727753. [PMID: 34568385 PMCID: PMC8460906 DOI: 10.3389/fmed.2021.727753] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2021] [Accepted: 08/16/2021] [Indexed: 11/13/2022] Open
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
Pregnancy is not contraindicated in kidney transplant women but entails risks of maternal and fetal complications. Three main conditions can influence the outcome of pregnancy in transplant women: preconception counseling, maternal medical management, and correct use of drugs to prevent fetal toxicity. Preconception counseling is needed to prevent the risks of an unplanned untimely pregnancy. Pregnancy should be planned ≥2 years after transplantation. The candidate for pregnancy should have normal blood pressure, stable serum creatinine <1.5 mg/dL, and proteinuria <500 mg/24 h. Maternal medical management is critical for early detection and treatment of complications such as hypertension, preeclampsia, thrombotic microangiopathy, graft dysfunction, gestational diabetes, and infection. These adverse outcomes are strongly related to the degree of kidney dysfunction. A major issue is represented by the potential fetotoxicity of drugs. Moderate doses of glucocorticoids, azathioprine, and mTOR inhibitors are relatively safe. Calcineurin inhibitors (CNIs) are not associated with teratogenicity but may increase the risk of low birth weight. Rituximab and eculizumab should be used in pregnancy only if the benefits outweigh the risk for the fetus. Renin-angiotensin system inhibitors, mycophenolate, bortezomib, and cyclophosphamide can lead to fetal toxicity and should not be prescribed to pregnant women.

Abstract
BACKGROUND Pre-eclampsia, the second most frequent direct source of maternal mortality, is a multisystem gestational disorder characterized by proteinuria and maternal hypertension after the 20th gestational week. Although the causes of pre-eclampsia are still discussed, research has suggested that the placenta has a central place in the pathogenesis of this disease. Moreover, current surveys indicated that periodontal disorders observed during the pregnancy and more particularly, periodontal pathogens could be link to the risk of pre-eclampsia. OBJECTIVES This article aims to review recent studies focusing on periodontal conditions and pathogens associated with pre-eclampsia. METHODS The process followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. RESULTS Metabolic conditions, immunological changes, fluctuating progesterone and estrogen levels of the pregnant woman induce a dysbiosis of the oral microbiota and contribute to increase inflammation of periodontal tissues. Periodontal pathogens could diffuse through the bloodstream inducing a placenta inflammatory response as well as inflammatory molecules produced in response to periodontopathogens could migrate through the bloodstream leading to a placenta inflammatory response. Also, periodontopathogens can colonize the vaginal microbiota through the gastrointestinal tract or during oro-genital contacts. CONCLUSION A cumulative bi-directional relationship between periodontal conditions, pathogens and the pre-eclampsia exists.

Soluble fms-like tyrosine kinase 1 (sFlt-1): A novel biochemical marker for acute fatty liver of pregnancy. Acta Obstet Gynecol Scand 2021; 100:1876-1884. [PMID: 34157141 DOI: 10.1111/aogs.14218] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2020] [Revised: 05/31/2021] [Accepted: 06/08/2021] [Indexed: 11/29/2022]
Abstract
INTRODUCTION Acute fatty liver of pregnancy (AFLP) substantially contributes to maternal and neonatal morbidity and mortality. Other liver-associated pregnancy complications such as preeclampsia-associated HELLP (hemolysis, elevated liver enzyme, low platelet) syndrome may be difficult to differentiate from AFLP as these diseases overlap with regard to multiple clinical and laboratory features. The aim of this study was to investigate angiogenic profiles by measuring soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) in pregnancies compromised by AFLP and to compare them with those complicated by HELLP syndrome. MATERIAL AND METHODS Pregnant women affected by AFLP or HELLP syndrome were enrolled. The study population of women with HELLP syndrome was part of a larger data collection obtained in our clinic that has been used for previous work. Patients' angiogenic profiles were assessed by measuring sFlt-1 and PlGF serum levels. To assess the diagnostic potential of these angiogenic markers in AFLP, as well as discriminating it from HELLP syndrome, non-parametric tests were used and receiver operating curves were calculated. RESULTS Six women with AFLP and 48 women with HELLP syndrome were included in the study. Patients with AFLP showed significantly higher sFlt-1 levels (median: 57 570 pg/mL; range 31 609-147 170 pg/mL) than patients with HELLP syndrome (9713 pg/mL; 1348-30 781 pg/mL; p < 0.001). PlGF serum levels were higher in patients with AFLP compared with those with HELLP syndrome (197 pg/mL; 127-487 pg/mL vs. 40 pg/mL; 9-644 pg/mL, respectively; p < 0.01). sFlt-1/PlGF ratios were not significantly different between AFLP and HELLP syndrome patients (192; 157-1159 vs. 232; 3-948, respectively; NS). In our study population, an sFlt-1 cut-off value of 31 100 pg/mL allowed differentiation between these two diseases with a sensitivity and specificity of 100%. A linear correlation was found between the cumulative numbers of Swansea criteria and sFlt-1 serum levels (r = 0.97; p < 0.01). CONCLUSIONS AFLP is associated with very high sFlt-1 serum levels in particular in women fulfilling eight or more Swansea criteria. Besides the suggested Swansea criteria to diagnose AFLP, an sFlt-1 value above 31 100 pg/mL may be an additional biochemical feature improving discrimination between AFLP and HELLP syndrome. However, because of the small number of pregnancies affected by AFLP included in this work further studies are needed to corroborate our findings.

Abstract
OBJECTIVE To compare the classification of the adequacy of birth weight for gestational age applying INTERGROWTH-21 (IG-21) and Fenton growth curves in preterm infants, and to relate this classification to the nutritional status at 12 months corrected age. METHODS This is a retrospective study with 173 preterm infants aged between 26 and 33 weeks. Data was collected on maternal health conditions, birth and gestational age anthropometric information, and anthropometry (weight, height, and head circumference) at 12 months corrected age. RESULTS The mean birth weight and gestational age were 1151.4 ± 227.2 g and 30.2 ± 2.4 weeks, respectively. Using percentiles of IG-21 and Fenton curves, the proportion of SGA and LGA preterm infants was 39.2% vs. 35.2%, and 3.5% vs. 3.5%, respectively (p = 0.520). At 12 months corrected age, short stature, overweight, and thinness were observed in 33.5%, 9.9%, and 11% of preterm infants, respectively. The ROC curve evidenced that the IG-21 was slightly better than Fenton to predict short stature (AUC = 0.626, 95% CI 0.537-0.715 and AUC = 0.600, 95% CI 0.506-0.694) and overweight (AUC = 0.648, 95% CI 0.527-0.769 and AUC = 0.618, 95% CI 0.486-0.750) at 12 months corrected age. In contrast, the ROC curve did not show an association of IG-21 and Fenton percentiles with thinness. CONCLUSIONS FOR PRACTICE This study showed that IG-21 and Fenton were similar for the classification of birth weight for gestational age in preterm infants. IG-21 was slightly better than Fenton to predict overweight and short stature in preterm infants at 12 months corrected age.

Abstract
Objective Baicalin is a compound extracted from the dried root of Scutellaria baicalensis Georgi. Studies have shown that baicalin has a protective effect on vascular endothelial cells, but whether baicalin could alleviate ascular endothelial cell damage in pregnancy-induced hypertensive patients remains unknown. Materials and methods We established a hypertensive pregnant rat model to study vascular endothelial injury during pregnancy-induced hypertension. Plasma epoprostenol (PGI-2), thromboxane A2 (Txa-2), β-human chorionic gonadotropin (β-HCG), and estrogen levels in rats were detected using ELISA. Vascular endothelial growth factor (VEGF), endothelial nitric oxide synthase (eNOS), and C-reactive protein (CRP) expression were detected using western blotting and quantitative PCR (q-PCR). Results Results showed that baicalin alleviated symptoms of pregnancy-induced hypertension. CRP, Txa-2, and β-HCG expression were significantly upregulated, while VEGF, eNOS, PGI-2, and estrogen expression was decreased in plasma and placental tissues of hypertensive rats. However, the levels of these injury indicators were significantly decreased after baicalin therapy, while the expression of protective indicators was significantly increased. Conclusion Baicalin reversed vascular endothelial cell injury in pregnant hypertensive rats by promoting VEGF, eNOS, PGI-2, and estrogen expression.

Abstract
Extracellular vesicles (EVs) are small vesicles ranging from 20–200 nm to 10 μm in diameter that are discharged and taken in by many different types of cells. Depending on the nature and quantity of their content—which generally includes proteins, lipids as well as microRNAs (miRNAs), messenger-RNA (mRNA), and DNA—these particles can bring about functional modifications in the receiving cells. During pregnancy, placenta and/or fetal-derived EVs have recently been isolated, eliciting interest in discovering their clinical significance. To date, various studies have associated variations in the circulating levels of maternal and fetal EVs and their contents, with complications including gestational diabetes and preeclampsia, ultimately leading to adverse pregnancy outcomes. Furthermore, EVs have also been identified as messengers and important players in viral infections during pregnancy, as well as in various congenital malformations. Their presence can be detected in the maternal blood from the first trimester and their level increases towards term, thus acting as liquid biopsies that give invaluable insight into the status of the feto-placental unit. However, their exact roles in the metabolic and vascular adaptations associated with physiological and pathological pregnancy is still under investigation. Analyzing peer-reviewed journal articles available in online databases, the purpose of this review is to synthesize current knowledge regarding the utility of quantification of pregnancy related EVs in general and placental EVs in particular as non-invasive evidence of placental dysfunction and adverse pregnancy outcomes, and to develop the current understanding of these particles and their applicability in clinical practice.

Abstract
Background This study investigated whether maternal serum D-dimer (DD) alone or DD combined with alpha-fetoprotein (AFP) and free β-subunit of human chorionic gonadotropin (free β-hCG) in the second trimester could be used to predict hypertensive disorders of pregnancy (HDP). Materials and methods In this retrospective case–control study, the data of gravidas patients who delivered at hospital were divided into the following groups: control (n = 136), gestational hypertension (GH, n = 126), preeclampsia (PE, n = 53), and severe preeclampsia (SPE, n = 41). Receiver operator characteristic (ROC) curves were used to evaluate the diagnostic value of maternal serum DD, AFP, and free β-hCG levels for HDP. Results DD levels of the GH, PE, and SPE groups were significantly higher than that of the control group (P < 0.001). The order of effectiveness for models predicting HDP was as follows: DD + AFP + free β-hCG > DD > DD + AFP > DD + free β-hCG > AFP + free β-hCG > AFP > free β-hCG. For predicting different types of HDP, DD alone had the best diagnostic value for SPE, followed by PE and GH. DD alone had a sensitivity of 100% with a 0% false negative rate and had the highest positive likelihood ratio (+ LR) for SPE. DD alone in combination with AFP alone, free β-hCG alone and AFP + free β-hCG could reduce false positive rate and improve + LR. Conclusion DD is possible the best individual predictive marker for predicting HDP. Levels of DD alone in the second trimester were positively correlated with the progression of elevated blood pressure in the third trimester, demonstrating the predicting the occurrence of HDP. The risk calculation model constructed with DD + free β-hCG + AFP had the greatest diagnostic value for SPE.

Abstract
This study intended to investigate the role of NFKB1 in oxidative stress injury and insulin resistance in gestational hypertension (GH) mice. Following establishment of a GH mouse model by high-fat diet, NFKB1, miR-106a, and FLOT2 expression was detected in liver of mice. After NFKB1, miR-106a, and FLOT2 were altered in GH mice by lentiviral vector, oxidative stress markers in liver tissues were examined by colorimetry, and insulin resistance was assessed by fasting blood glucose and fasting insulin levels. Next, hepatocytes were isolated from GH mice and treated with miR-106a mimic, inhibitor or siRNA, followed by determination of hepatocyte apoptosis and the expression of inflammation- and apoptosis-related factors. Evaluation of the correlations among NFKB1, miR-106a, and FLOT2 were conducted. Liver of GH mice harbored NFKB1 and FLOT2 upregulation and miR-106a downregulation. miR-106a was transcriptionally inhibited by NFKB1, and negatively targeted FLOT2. Oxidative stress injury and insulin resistance in GH mice and apoptosis and inflammation of hepatocytes from GH mice were decreased after silencing NFKB1 or FLOT2 or overexpressing miR-106a. These findings provided evidence demonstrating the inhibitory effect of NFKB1 silencing on oxidative stress injury and insulin resistance in GH mice via miR-106a upregulation and FLOT2 downregulation.

Preeclamptic Women Have Decreased Circulating IL-10 (Interleukin-10) Values at the Time of Preeclampsia Diagnosis: Systematic Review and Meta-Analysis. Hypertension 2020; 76:1817-1827.

Abstract
A key immunomodulatory cytokine, IL-10 (interleukin-10), has been shown to be dysregulated in preeclampsia, a pregnancy-specific hypertensive disorder, further characterized by multi-system involvement. However, studies have reported inconsistent findings about circulating IL-10 levels in preeclamptic versus normotensive pregnancies. The aim of the present systematic review and meta-analysis was to assess circulating IL-10 levels in preeclamptic and normotensive pregnancies at 2 time points: before, and at the time of preeclampsia diagnosis. PubMED, EMBASE, and Web of Science databases were searched to include all published studies examining circulating IL-10 levels in preeclamptic and normotensive pregnancies. Differences in IL-10 levels were evaluated by standardized mean differences. Of 876 abstracts screened, 56 studies were included in the meta-analysis. Circulating IL-10 levels were not different before the time of active disease (standardized mean differences, -0.01 [95% CI, -0.11 to 0.08]; P=0.76). At the time of active disease, women with preeclampsia (n=1599) had significantly lower IL-10 levels compared with normotensive controls (n=1998; standardized mean differences, -0.79 [95% CI, -1.22 to -0.35]; P=0.0004). IL-10 levels were lower in both early/severe and late/mild forms of preeclampsia. Subgroup analysis revealed that IL-10 measurement methodology (ELISA or multiplex bead array) and the sample type (plasma or serum) significantly influenced the observed differences, with the use of sera paired with ELISA technology providing the best distinction in IL-10 levels between preeclamptic and normotensive pregnancies. These findings support the role of decreased IL-10 levels in the pathophysiology of preeclampsia. Future studies should address the therapeutic potential of IL-10 in preeclampsia.

Abstract
Magnesium as an enzymatic activator is essential for various physiological functions such as cell cycle, metabolic regulation, muscle contraction, and vasomotor tone. A growing body of evidence supports that magnesium supplementation (mainly magnesium sulfate and magnesium oxide) prevents or treats various types of disorders or diseases related to respiratory system, reproductive system, nervous system, digestive system, and cardiovascular system as well as kidney injury, diabetes and cancer. The ongoing pandemic coronavirus disease 19 (COVID-19) characterized by respiratory tract symptoms with different degrees of important organ and tissue damages has attracted global attention. Particularly, effective drugs are still lacking in the COVID-19 therapy. In this review, we find and summarize the effectiveness of magnesium supplementation on the disorders or diseases, and provide a reference to the possibility of magnesium supplementation for supportive treatment in patients with COVID-19.

Abstract
Objective: The present study analyzed the fetal–placental hemodynamic parameters in women with severe preeclampsia in second- and third-trimester pregnancy with a view to developing effective predictive indicators for preeclampsia and providing support for the prenatal clinical treatment of preeclampsia. Materials and Methods: From January 2015 to January 2019, 160 pregnant women diagnosed with severe preeclampsia at Xiangyang First People’s Hospital were recruited as the study group. The diagnostic criteria for preeclampsia were in accordance with the guidelines of the International Society for the Study of Hypertension in Pregnancy (ISSHP). A sample of 160 healthy pregnant women with normal blood pressure were selected as the control group. The GE Voluson E8 and E10 four-dimensional (4D) ultrasonic diagnostic instruments and the three-dimensional (3D) power Doppler in angio-quantitative mode were used to measure the hemodynamic parameters of the placenta, left uterine artery (LUA), right uterine artery (RUA), middle cerebral artery (MCA), umbilical artery (UA), and ductus venosus (DV) in the two groups. The above parameters were analyzed statistically using SPSS 22.0. Results: The systolic/diastolic velocity ratio (S/D), pulsatility index (PI), and resistance index (RI) of the MCA in the study group were lower than those of normal subjects of the same gestational age (P < 0.05). These parameters in the UA were higher in the study group than those in normal subjects (P < 0.05). The ratios between the peak ventricular systolic velocity and the peak atrial systolic velocity (S/A), pulsatility index for the vein (PIV), pre-load index (PLI), and peak velocity index for the vein (PVIV) in the DV were significantly different between the study and normal groups (P < 0.05). The placental vascularization index (VI), flow index (FI), and vascularization flow index (VFI) were lower in the study group than those in normal subjects of the same gestational age (P < 0.05). There were good correlations between VI, VFI and RUA, PI, with correlation coefficients of −0.697 and −0.702, respectively. FI was the indicator that had the highest diagnostic efficacy for severe preeclampsia. The predictive sensitivity of the FI with a cut-off value of 34.92 was 96.3%, and the corresponding specificity was 86.9%. Conclusions: Placental FI had the highest predictive efficacy for severe preeclampsia and provides a reliable quantitative indicator and data support for preeclampsia management. 3D power quantitative Doppler ultrasound provides a novel avenue for the study of severe preeclampsia.

Abstract
PURPOSE To test the predictive value of ophthalmic artery (OA) Doppler velocimetry in relation to the occurrence of hypertensive disorders of pregnancy (HDP). METHODS We compared, by analysis of variance, the values of seven OA Doppler variables (peak systolic velocity, second systolic peak velocity [P2], mean velocity, end diastolic velocity, resistance index [RI], pulsatility index [PI], and peak ratio) of 31 women with preeclampsia and 33 women with gestational hypertension vs those of 227 women without HDP. The prognostic value of these variables in relation to the occurrence of HDP was evaluated by the area under the curve (AUC) receiver operating characteristic curve. RESULTS All OA Doppler variables except RI and PI showed significant (P < .5) differences between groups. After adjustment for confounders, only P2 was an independent predictor of HDP (P < .001), with an AUC of 0.76. The best cut-off point for predicting HDP was P2 ≥ 21.4 cm/s, with sensitivity 69%, specificity 78%, positive likelihood ratio 3.1, negative likelihood ratio 0.4, positive predictive value 47%, and negative predictive value 90%. P2 improved the predictive ability of a model based on clinical variables, incrementing AUC from 0.77 to 0.84 in the final model containing clinical and Doppler variables. CONCLUSION The elevation of OA P2 in the second trimester of pregnancy is an independent predictor of hypertensive disorders, and improves the discriminatory ability of clinical markers.

Abstract
Background The association between gestational weight gain and neonatal body composition has been inconsistent, exposing the need for further research. The aim of this study was to evaluate whether gestational weight gain influences the body composition of full-term newborns and infants up to 4 months old. Methods A cohort study was performed with 124 participants divided into categories of gestational weight gain according to the 2009 Institute of Medicine guidelines. The anthropometric and body composition data of newborns and infants acquired using air displacement plethysmography (PeaPod®) were collected at 96 h, 1 month, 2 months and 4 months of life. In the statistical analysis, the chi-square test was used to analyze categorical variables, and ANOVA was used to analyze numerical variables. Univariate analysis was performed, and the absolute and relative frequencies of the categorical variables, as well as mean and standard deviation of the numerical variables, were obtained. Bivariate analysis was performed for the categories of gestational weight gain and gestational and neonatal characteristics. When adjustments to gestational hypertension, gestational diabetes, and pregestational body mass index (BMI) were analyzed by linear regression, gestational weight gain remained a significant variable for newborn percent fat mass. For all analyses, a significance level of 5% was adopted. Results Gestational weight gain was adequate in 33.8% of the participants, excessive in 41.1% and insufficient in 25%. Women with excessive weight gain had higher pregestational BMIs and a higher incidence of gestational hypertension. Their newborns had a higher body mass, body fat mass in grams and percent fat mass than the infants born to mothers with adequate or insufficient gestational weight gain. No significant differences were observed in body composition at 1, 2 and 4 months of life during infant follow-up. Conclusion Excessive gestational weight gain may alter the body composition of newborns at birth. Further studies are required to better evaluate infant follow-up.

Future Directions: Analyzing Health Disparities Related to Maternal Hypertensive Disorders. J Pregnancy 2020; 2020:7864816.

Abstract
Hypertensive disorders of pregnancy complicate up to 10% of pregnancies worldwide, constituting one of the most significant causes of maternal morbidity and mortality. Hypertensive disorders, specifically gestational hypertension, chronic hypertension, and preeclampsia, throughout pregnancy are contributors to the top causes of maternal mortality in the United States. Diagnosis of hypertensive disorders throughout pregnancy is challenging, with many disorders often remaining unrecognized or poorly managed during and after pregnancy. Moreover, the research has identified a strong link between the prevalence of maternal hypertensive disorders and racial and ethnic disparities. Factors that influence the prevalence of maternal hypertensive disorders among racially and ethnically diverse women include maternal age, level of education, United States-born status, nonmetropolitan residence, prepregnancy obesity, excess weight gain during pregnancy, and gestational diabetes. Examination of the factors that increase the risk for maternal hypertensive disorders along with the current interventions utilized to manage hypertensive disorders will assist in the identification of gaps in prevention and treatment strategies and implications for future practice. Specific focus will be placed on disparities among racially and ethnically diverse women that increase the risk for maternal hypertensive disorders. This review will serve to promote the development of interventions and strategies that better address and prevent hypertensive disorders throughout a pregnant woman's continuum of care.

Pregnancy-related acute kidney injury: mortality and survival of patients treated at a maternal intensive care unit. J Nephrol 2020; 33:1361-1367. [PMID: 32072506 DOI: 10.1007/s40620-020-00711-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2019] [Accepted: 02/08/2020] [Indexed: 12/14/2022]
Abstract
INTRODUCTION Pregnancy-related acute kidney injury (AKI) can be defined as the abrupt decline in renal function during pregnancy or the postpartum period. It remains a relevant cause of fatal complications in obstetric patients. This study aimed to determine the incidence of pregnancy-related AKI in a maternal intensive care unit (ICU) as well as the associated risk factors for dialysis therapy and maternal mortality according to the KDIGO classification system. METHODS Retrospective analysis of observational data prospectively collected from January/2014 to April/2016 in a maternal ICU in a public tertiary maternal hospital in Brasília, Federal District, Brazil. All consecutive patients diagnosed with pregnancy-related AKI were included. Cases of renal failure before pregnancy or kidney transplantation were excluded. RESULTS Of the 619 admitted patients, pregnancy-related AKI was present in 172 cases (27.8%). One hundred and ten patients were classified as KDIGO 1 (64.0%), 43 as KDIGO 2 (20.9%) and 22 as KDIGO 3 (15.1%). KDIGO stages 2 and 3 were less frequent than KDIGO stage 1 in patients with gestational hypertension (p = 0.0010). Thirteen patients required hemodialysis (7.6%). Higher APACHE II (p = 0.0399) and SOFA (p = 0.0297) scores, hypovolemic shock (p = 0.0189) and septic shock (p = 0.0204) were independently associated with dialysis therapy (hemodialysis in all cases), 15 patients died (8.7%). Time to death was shorter in patients with a higher KDIGO stage (p = 0.002). Norepinephrine (p = 0.0384) and hemodialysis therapy (p = 0.0128) were independently associated with maternal mortality. CONCLUSIONS The incidence of pregnancy-related AKI remains high in the maternal ICU setting. Septic shock, hypovolemic shock, and higher APACHE II and SOFA scores were independently associated dialysis therapy (hemodialysis in all cases). KDIGO stages 2 and 3 were less frequent than KDIGO stage 1 in patients with gestational hypertension. Norepinephrine and hemodialysis therapy were independently associated with maternal mortality in patients with pregnancy-related AKI. KDIGO stage 3 was associated with higher maternal mortality.

Abstract
Intracranial hemorrhage and stroke are primary causes of maternal mortality in pregnancies affected by hypertensive disorders. As such antihypertensive therapy plays a crucial role in the management of severe hypertension. However, the target level to achieve the best outcome for both - mother and fetus - is still unclear. Moreover, given the lack of well-designed randomized controlled trials with standardized key outcomes, the current choice of antihypertensive medications depends rather on clinicians' preference. Furthermore, data on long-term outcomes of offspring is not available. Therefore, there is an urgent need for randomized trials comparing different anti-hypertensive options to address efficacy and safety questions.

Abstract
Hypertensive disorders of pregnancy, an umbrella term that includes preexisting and gestational hypertension, preeclampsia, and eclampsia, complicate up to 10% of pregnancies and represent a significant cause of maternal and perinatal morbidity and mortality. Despite the differences in guidelines, there appears to be consensus that severe hypertension and non-severe hypertension with evidence of end-organ damage need to be controlled; yet the ideal target ranges below 160/110 mmHg remain a source of debate. This review outlines the definition, pathophysiology, goals of therapy, and treatment agents used in hypertensive disorders of pregnancy.
