OBJECTIVES: To assess maternal characteristics and comorbidities in patients with persistent uninterpretable non-invasive prenatal testing (NIPT) and to evaluate the association with adverse pregnancy outcome in a general risk population. METHODS: A retrospective cohort study (July 2017-December 2020) was conducted of patients with persistent uninterpretable NIPT samples. Maternal characteristics and pregnancy outcomes were compared with the general Belgian obstetric population...

BACKGROUND: Pregnant people are particularly vulnerable to SARS-CoV-2 infection and to ensuing severe illness. Predicting adverse maternal and perinatal outcomes could aid clinicians in deciding on hospital admission and early initiation of treatment in affected individuals, streamlining the triaging processes. METHODS: An international repository of 1501 SARS-CoV-2-positive cases in pregnancy was created, consisting of demographic variables, patient comorbidities, laboratory markers, respiratory parameters, and COVID-19-related symptoms...

BACKGROUND: Pregnancies after solid organ transplant are at a higher risk of antepartum admission and pregnancy complications including cesarean delivery. Emergent prelabor cesarean delivery is associated with increased maternal and neonatal morbidity in other high-risk populations, but its incidence and impact in transplant recipients is not well-understood. OBJECTIVE: This study aimed to characterize the risk factors and outcomes of emergency prelabor cesarean delivery in kidney and liver transplant recipients...

AIM: Low-dose aspirin (LDA) has been shown to reduce the incidence of preeclampsia (PE). Previous studies have focused on the timing of LDA initiation, but no study to date has assessed the timing of LDA discontinuation. This study aimed to evaluate the effect of LDA when LDA is initiated between 12 and 16 weeks of gestation and continued until 28 weeks of gestation. METHODS: This prospective cohort study with historical controls investigated singleton pregnancies that were at a high risk for PE...

OBJECTIVE:  Shallow placental implantation (SPI) features placental maldistribution of extravillous trophoblasts and includes excessive amount of extravillous trophoblasts, chorionic microcysts in the membranes and chorionic disc, and decidual clusters of multinucleate trophoblasts. The histological lesions were previously and individually reported in association with various clinical and placental abnormalities. This retrospective statistical analysis of a large placental database from high-risk pregnancy statistically compares placentas with and without a composite group of features of SPI...

Background: Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease during pregnancy. Studies of risk factors are of great significance to maternal and fetal outcomes in patients with TOF. Aims: To identify predictive risk factors for maternal and perinatal complications in women with TOF. Subjects and Methods: 78 patients with TOF who delivered at Shanghai Obstetrical Cardiology Intensive Care Center between January 1993 and December 2017 were retrospective reviewed...

BACKGROUND: IVM was implemented in medically assisted reproduction 25 years ago. IVM does not involve controlled ovarian stimulation (COS) and is mainly indicated in patients with a high risk of ovarian hyperstimulation syndrome, in particular in patients with polycystic ovary syndrome (PCOS); it is also an acknowledged option in fertility protection. However, the in-vitro culture of immature oocytes raises concerns over their developmental potential and the putative impact on children's health...

Telemedicine involves the use of technology to provide services to patients and share medical information. Telemedicine's use has increased as technology has advanced. It allows for medicine to be practiced from a distance to reach patients in rural or underserved areas. Telemedicine has widespread uses in high-risk obstetrics, including management of diabetes, diagnosis and management of hypertensive disorders of pregnancy, screening for fetal malformations with teleultrasound, delivering care to underserved areas, and more...

The aim of this review is to summarize the current literature regarding a link between endometriosis and adverse pregnancy outcomes. We also present an overview of common pathogenic mechanisms between endometriosis and obstetric complications. A computerized literature search was performed to identify relevant studies. The search covered the period between January 2008 and October 2018. Emerging evidence has revealed that endometriosis increased the risk of preterm birth, miscarriage, preterm premature rupture of membranes, placenta previa, preeclampsia, pregnancy-induced hypertension (PIH), gestational diabetes, gestational cholestasis, small for gestational age (SGA) babies, antepartum hemorrhage, postpartum hemorrhage, placental abruption, retained placenta, malpresentation, labor dystocia, cesarean delivery, stillbirth, neonatal death, and congenital malformations of the uterus, but the data are based on limited information...

BACKGROUND Congenital renal vascular anomalies have been classified into 3 categories: cirsoid, angiomatous, and aneurysmal. These classifications are based on the size, location, and number of vessels involved. Aneurysmal malformations, such as the one reported here, have a single (and dilated) feeding and draining vessel. The prevalence of renal AVMs is estimated at less than 0.04%, making them rare causes of secondary hypertension. CASE REPORT A 29-year-old white woman was seen in the hypertension clinic as a referral from high-risk obstetric clinic for management of hypertension (HTN)...

Objective: To explore the high risk factors of stillbirth. Methods: 176 cases of stillbirth were collected in the Obstetrics and Gynecology Hospital of Fudan University from January 1(st), 2010 to December 31(st), 2016. All cases were analyzed retrospectively, including general profile, high risk factors of stillbirth in different years and pregnancy periods. Results: (1) The incidence of stillbirth was 0.178%(176/98 785). Stillbirth occured mostly at 28-28(+6) gestational weeks (10.8%,19/176), and the second peak was 29-29(+6) weeks(10...

Objective: To investigate the perinatal outcome, risk factors and long-term outcome of pregnancy complicated with pulmonary arterial hypertension(PAH) and congenital heart diseases (CHD). Methods: Clinical data of 110 pregnant women who were diagnosed as PAH-CHD were retrospectively analyzed in the Department of Obstetrics and Gynecology and Surgical Intensive Care Unit at Beijing Anzhen Hospital from 2004 to 2013. The survival and treatment status were followed up. Results: 110 subjects consisted of 11 mild PAH, 33 moderate and 66 severe ones...

OBJECTIVE: To determine whether there are any increases in pregnancy-related complications and adverse pregnancy outcomes in singleton pregnancies after assisted reproductive technology (ART) compared with those conceived naturally. DESIGN: Meta-analysis. SETTING: University-affiliated teaching hospital. PATIENT(S): Singleton pregnancies conceived with ART and naturally. INTERVENTION(S): PubMed, Google Scholar, Cochrane Libraries and Chinese database were searched through March 2015 to identify studies that met pre-stated inclusion criteria...

BACKGROUND: Antenatal care of women with epilepsy is varied. The association of epilepsy and antiepileptic drug exposure with pregnancy outcomes needs to be quantified to guide management. We did a systematic review and meta-analysis to investigate the association between epilepsy and reproductive outcomes, with or without exposure to antiepileptic drugs. METHODS: We searched MEDLINE, Embase, Cochrane, AMED, and CINAHL between Jan 1, 1990, and Jan 21, 2015, with no language or regional restrictions, for observational studies of pregnant women with epilepsy, which assessed the risk of obstetric complications in the antenatal, intrapartum, or postnatal period, and any neonatal complications...

BACKGROUND: No national research on maternal and fetal complications and outcomes has been carried out in the mainland of China in recent years. This study was to provide a scientific basis for better control of obstetrical and neonatal diseases and better allocation of medical resources by analyzing the epidemiological characteristics of obstetrical diseases in the mainland of China. METHODS: Hospitalized obstetrical cases from 19 tertiary and 20 secondary hospitals in 14 provinces (nationally representative) during the period January 1, 2011 to December 31, 2011 were randomly selected...

PURPOSE: To analyze the relationships among gestational risk, type of delivery and immediate maternal and neonatal repercussions. METHODS: A retrospective cohort study based on secondary data was conducted in a university maternity hospital. A total of 1606 births were analyzed over a 9-month period. Epidemiological, clinical, obstetric and neonatal characteristics were compared according to the route of delivery and the gestational risk characterized on the basis of the eligibility criteria for high clinical risk...

AIM: Women with congenital heart disease are often considered to be restricted in their obstetrical life and even their marital life. Our single-centre study aimed to determine the real-life situation of these women with regard to successful family life and any pregnancy complications they may experience. METHODS: From our database of adults with congenital heart disease, 160 of 178 women completed a questionnaire and had their files reviewed. They were classified into three groups according to their pregnancy risk - "good condition" group, no pregnancy restriction; "at-risk" group, pregnancy allowed with close follow-up at a tertiary centre; and "contraindicated" group, pregnancy inadvisable...
