Abstract
We aimed to investigate the blood pressure (BP) patterns of hypertensive disorders of pregnancy (HDP) in the first and second trimesters and its contributing factors, which may help us understand its pathogenesis and identify this group of diseases in a timely manner. SPSS 21.0 was used to describe the BP patterns of 688 HDP as well as 2050 normotensive pregnancies respectively before 28 gestational weeks, and the repeated measurements and two-way ANOVA was used to decide the significant difference of blood pressure in the same period. The results revealed blood pressure in HDP underwent a mid-pregnancy drop as normal while the drop was unremarkable in advanced-age or obesity pregnancies. Besides, we found blood pressure was significantly higher in patients during first and second trimesters, not just after 20 weeks. In conclusion, our study indicated a significant elevation of blood pressure had appeared before 20 weeks in HDP pregnancies, we should pay more attention to monitoring blood pressure before 20 weeks, especially for advanced age and obese women.IMPACT STATEMENTWhat is already known on this subject? Gestational hypertension, preeclampsia as well as eclampsia were supposed to have the similar pathogenesis and their time of onset was strictly defined after 20 gestational weeks, while the reason for the time point was not clear. On the other hand, higher blood pressure in the first trimester was associated with increasing risk of developing HDP, while the blood pressure(BP) pattern of normal as well as HDP pregnancy was still controversial, especially for the existence of mid-trimester drop.What do the results of this study add? Firstly, we found blood pressure in HDP underwent a mid-pregnancy drop as normal while the BP drop was unremarkable in advanced-age or obesity pregnancies. Secondly, we noticed the blood pressure in HDP was significantly higher than the normal before 20 weeks, which had not been proved before.What are the implications of these findings for clinical practice and/or further research? On one hand, both the abnormal elevation of BP and the development of the placenta happened in the first trimester suggested toxic substances caused by the defective placenta played a vital role in the onset and aggravation of HDP, which guides us to pay more attention to monitor blood pressure before 20 weeks, especially for advanced age and obesity pregnancies. On the other hand, our results about BP patterns in HDP help us identify this group of diseases in time which can contribute to a better outcome.

Population-based study on birth outcomes among women with hypertensive disorders of pregnancy and gestational diabetes mellitus. Sci Rep 2021; 11:17391. [PMID: 34462468 PMCID: PMC8405617 DOI: 10.1038/s41598-021-96345-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Accepted: 08/09/2021] [Indexed: 12/16/2022] Open
Abstract
To evaluate birth outcomes in women with hypertensive disorders of pregnancy (HDP) and gestational diabetes mellitus (GDM), we used insurance data of Taiwan to evaluate 11 adverse neonatal outcomes of infants born to women with HDP (N = 7775) and with both HDP and GDM (HDP/GDM) (N = 1946), comparing to women with neither disorder (N = 19,442), matched by age. The impacts of preeclampsia/eclampsia were also evaluated. Results showed that Caesarean section delivery was near 1.7-fold greater in the HDP/GDM and HDP groups than in comparisons. The preterm delivery rates were more than threefold greater in HDP/GDM group and HDP group than in comparisons with adjusted odds ratios (aORs) of 4.84 (95% confidence interval (CI) 4.34–5.40) and 3.92 (95% CI 3.65–4.21), respectively, followed by jaundice (aORs 2.95 (95% CI 2.63–3.33) and 1.90 (95% CI 1.76–2.06)), and small gestation age (SGA) (aORs 6.57 (95% CI 5.56–7.75) and 5.81 (95% CI 5.15–6.55)). Incidence rates of birth trauma, patent ductus arteriosus, atrial septal defect, respiratory distress syndrome, and neonatal hypoglycemia were also higher in the HDP/GDM and HDP groups than in the comparison group. Most adverse outcomes increased further in women with preeclampsia or eclampsia. In conclusion, women with HDP are at elevated risks of adverse neonatal outcomes. Risks of most adverse outcomes increase further for women with both HDP and GDM. Preeclampsia or eclampsia may also contribute to these outcomes to higher risk levels. Every pregnant woman with these conditions deserves specialized prenatal care.

Abstract
Background Retained placenta represents a cause of maternal morbidity and mortality affecting 0.5–3% of all vaginal deliveries. The unpredictability of this condition makes difficult to develop predictive and preventive strategies to apply in clinical practice. This analysis collected and analyzed all known risk factors related to this obstetric complication. Methods A systematic literature review for all original research articles published between 1990 and 2020 was performed. Observational studies about retained placenta risk factors published in English language were considered eligible. Conference abstracts, untraceable articles and studies focused on morbidly adherent placenta were excluded. The included articles were screened to identify study design, number of enrolled patients and retained placenta risk factors investigated. All stages of the revision followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. Results Thirty-five studies met the inclusion criteria. The reported retained placenta prevalence ranged from 0.5 to 4.8%. Maternal age, previous cesarean sections, previous dilation and curettage, previous retained placenta, labor induction, resulted as the most recurrent, independent risk factors for retained placenta. Previous estro-progestins therapy, morphological placental features (weight, shape, insertion of umbilical cord, implantation site), endometriosis, Assisted Reproductive Technologies, Apgar score are fascinating new proposal risk factors. Conclusions Old and new data are not enough robust to draw firm conclusions. Prospective and well-designed studies, based on a well agreed internationally retained placenta definition, are needed in order to clarify this potential dramatic and life-threatening condition.

Complications of the third stage of labor in in vitro fertilization pregnancies: an additional expression of abnormal placentation? Fertil Steril 2020; 115:1007-1013. [PMID: 33272620 DOI: 10.1016/j.fertnstert.2020.10.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2020] [Revised: 10/01/2020] [Accepted: 10/01/2020] [Indexed: 12/31/2022]
Abstract
OBJECTIVE To assess the correlation between in vitro fertilization (IVF) and complications of the third stage of labor. DESIGN Retrospective cohort of vaginal deliveries from November 2008 to January 2020. Maternal and obstetric outcomes of singleton deliveries were compared between IVF and non-IVF pregnancies. SETTING University hospital. PATIENT(S) Women with live singleton vaginal deliveries at >24 weeks of gestation. INTERVENTION(S) In vitro fertilization-attained pregnancies (compared with spontaneous ones). MAIN OUTCOME MEASURE(S) Complications of the third stage of labor, defined as manual placental removal (either entire removal due to nonseparation or exploration of the uterine cavity due to suspected retained products of conception). RESULT(S) Overall, 1,264 IVF pregnancies and 34,166 non-IVF pregnancies were included. Deliveries in the IVF group were characterized by an older maternal age, lower parity, higher rate of diabetes and hypertensive disorders, higher rate of placental abnormalities, earlier gestational age, higher rate of labor induction, chorioamnionitis, and instrumental delivery. Complications of the third stage of labor occurred in 5.9% of IVF deliveries and in 2.8% of controls, and blood transfusion was more prevalent in IVF deliveries. The rate of complications of the third stage were higher in both fresh and frozen transfer cycles as compared with spontaneous pregnancies (5.8%, 8.8%, and 2.8%, respectively), although no difference was noted between fresh and frozen transfers. In vitro fertilization was associated independently with complications of the third stage of labor after adjustment for potential confounders. CONCLUSION(S) In vitro fertilization is associated independently with an increased risk of complications of the third stage of labor.

In vitro fertilization is associated with the onset and progression of preeclampsia. Placenta 2019; 89:50-57. [PMID: 31675490 DOI: 10.1016/j.placenta.2019.09.011] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2019] [Revised: 08/16/2019] [Accepted: 09/22/2019] [Indexed: 02/06/2023]
Abstract
OBJECTIVE We aimed to estimate the risk of preeclampsia (PE) associated with in vitro fertilization (IVF) and potential predisposing factors responsible for the observed association. METHODS This retrospective cohort study included 114485 pregnant women who delivered at the Nanjing Maternity and Child Health Care Hospital between 2013 and 2018. Of the 114485 women, 4601 (4%) conceived through IVF (IVF group) and 109884 (96%) conceived spontaneously (SC group). We performed logistic regression analysis to evaluate the risk of PE following IVF compared to spontaneous conception (SC). Then, we used propensity score matching analysis to compare the clinical characteristics and pregnancy outcomes between IVF patients with and without PE. RESULT There were 1339 PE cases in the total study population, with a significantly higher incidence of PE in IVF relative to spontaneous pregnancies (6.1% vs. 1.0%, p < 0.01). Severe PE was more prevalent in singleton IVF-PE group than in singleton SC-PE group (40% vs. 24.1%, p = 0.025). Placenta accreta was more common in singleton preeclamptic patients with IVF than without IVF (12.5vs.2.6%, p = 0.003). Placental hypoxia was more prevalent in twin IVF pregnancies with PE than without PE (6% vs. 12.2%, p = 0.045). Moreover, the IVF-PE group showed more frequent first-trimester bleeding (31.6% vs. 10.5%, p = 0.024) compared to the control group. CONCLUSION IVF is associated with the onset and progression of PE. Defective placentation and placental insufficiency may predispose IVF patients to PE and may manifest as first-trimester bleeding.

Abstract
OBJECTIVE To examine whether prior cesarean delivery (CD) in the first stage of labor (non-progressive labor in the first stage - NPL1), when compared with CD in the second stage of labor (non-progressive labor in the second stage - NPL2), is associated with different rates of third stage placental complications in the subsequent delivery. METHODS A retrospective cohort study, of all deliveries following a CD due to NLP1 or NLP2 that occurred between the years 1988 and 2013, was undertaken. Multiple gestation pregnancies, known uterine malformations or uterine fibroids were excluded. Rates of third stage complications (retained placenta, adherent/increta/percreta placenta, manual removal of the placenta) were compared between the groups. Univariate analysis was followed by multivariate analysis. RESULTS During the study period, there were 3828 subsequent deliveries of parturients who were operated due to NPL1 and NPL2 (72.91 and 27.09%, respectively). Rates of manual removal of the placenta as well as adherent placenta were significantly higher among parturients following CD due to NPL2 (28.4 versus 24.0%, p = .04, 1.2 versus 0.4% p < .01, respectively). In a multivariate analysis controlling for possible confounders, adherent placenta was found to be independently associated with vaginal delivery following CD due to NPL2 (odds ratio 2.98, 95% confidence interval 1.30-6.77). CONCLUSIONS Prior CD due to NPL2 as opposed to NPL1 is independently associated with adherent placenta in the subsequent delivery. A higher index of suspicion may be needed when evaluating these women during pregnancy as well as during management of the delivery.
