Termination of pregnancy

Misoprostol is a prostaglandin analogue that contracts the uterus, prompting the expulsion of the embryo. No systematic evaluation of the mechanisms of misoprostol has previously been performed. In this study, known targets of misoprostol were obtained from the DrugBank database; potential targets of misoprostol were predicted using data from the SwissTargetPrediction and PharmMapper databases; and the main targets of pregnancy termination were obtained from the GeneCards database. The protein-protein interaction (PPI) network of the shared genes between misoprostol and pregnancy termination was constructed using data from the STRING database, and the "misoprostol-pregnancy termination-pathway" network was constructed and potential targets was verified through molecular docking...

Spinal muscular atrophy (SMA) is a neuromuscular disorder with an autosomal recessive inheritance pattern. Patients with severe symptoms may suffer respiratory failure, leading to death. The homozygous deletion of exon 7 in the SMN1 gene accounts for nearly 95% of all cases. Population carrier screening for SMA and prenatal diagnosis by amniocentesis for high-risk couples can assist in identifying the risk of fetal disease. We provided the SMA carrier screening process to 55,447 pregnant women in Yancheng from October 2020 to December 2022...

OBJECTIVE: This study aims to investigate the expression levels of soluble CD40L (sCD40L), matrix metalloproteinase 2 (MMP2), and matrix metalloproteinase 9 (MMP9) in the serum of patients experiencing recurrent abortion and their impact on uterine artery blood flow. METHODS: A cohort of 200 patients with recurrent abortion was selected for this investigation. The levels of sCD40L, MMP2, and MMP9 in serum were assessed using ELISA, while ultrasound was employed to measure the pulsatility index (PI) and resistance index (RI) in uterine artery blood flow...

AIM: Assessing the socio-demographic factors on termination of pregnancy in Ghana. DESIGN: Cross-sectional study, using data source from the Demographic Health Survey (DHS). METHODS: Data pooled from the most recent DHS conducted in Ghana, with variables of interest with rural and urban population coverage. A systematic search of the literature was performed using PubMed, Google Scholar and Elsevier PubMed for the secondary data. Descriptive and logistic regression analysis was performed using Python Pandas' software to estimate the independent effects of the socio-demographic factors on termination of pregnancy in Ghana...

BACKGROUND: Emerging evidence supporting the use of valaciclovir to reduce fetal infection after maternal primary cytomegalovirus (CMV) infection has stimulated interest in routine CMV serological screening in pregnancy. It is important to understand the healthcare consumer perspective of a CMV infection during pregnancy to minimize unintended harms of screening. METHODS: We conducted a qualitative study using semi-structured interviews with Australian women who had a lived experience of CMV infection following serological testing during pregnancy...

OBJECTIVES: This study aimed to examine pregnancy and fetal outcomes following paternal exposure to glatiramer acetate (GA). METHODS: Pregnancy reports of paternal GA-exposure at time of conception from 2001 - 2022 were extracted from Teva Global Pharmacovigilance database. Pregnancy reports obtained prior to (prospective) or after (retrospective) knowledge of the pregnancy outcome were included. The primary endpoint was major congenital malformation (MCM) in the offspring according to the US Metropolitan Atlanta Congenital Defects Program (MACDP) and European Surveillance of Congenital Anomalies and Twins (EUROCAT) classification...

Calcitriol circulates at low levels in normal human and rodent fetuses, in part due to increased 24-hydroxylation of calcitriol and 25-hydroxyvitamin D by 24-hydroxylase (CYP24A1). Inactivating mutations of CYP24A1 cause high postnatal levels of calcitriol and the human condition of infantile hypercalcemia type 1, but whether the fetus is disturbed by the loss of CYP24A1 is unknown. We hypothesized that loss of Cyp24a1 in fetal mice will cause high calcitriol, hypercalcemia, and increased placental calcium transport...

INTRODUCTION AND IMPORTANCE: Dandy Walker variant is an intracranial disorder involving variable hypoplasia of cerebellar vermis without posterior fossa enlargement. An anomaly scan performed at mid second trimester has good sensitivity and specificity for detecting foetal congenital anomalies. Despite that, some cases like the authors' might go undiagnosed due to normal biometric parameters for that gestational age and may be detected later in intrauterine life. CASE PRESENTATION: A primi-gravid mother underwent sonographic evaluation at 20+4 weeks of gestation that revealed all foetal parameters within normal limits...

BACKGROUND: The clinical manifestations of trisomy 7 mosaicism are diverse and nonspecific, so prenatal diagnosis is very difficult. CASE SUMMARY: Two pregnant women with abnormal prenatal screening results were included. One was a 22-year-old woman (G1P0). At 31st week of gestation, ultrasound revealed that the posterior horn of the left lateral ventricle was 10 mm and the right renal pelvis had a separation of 7 mm. The other pregnant woman was 33 years old (G2P1L1A0), and her fetus was found to have a cardiac malformation at the 24th week of gestation...

BACKGROUND: This study aimed to explore the possible etiology and treatment of severe fetal tachycardia in the absence of organic disease and provide a reference for clinical management of severe fetal tachycardia. CASE SUMMARY: A 29-year-old pregnant woman, with a gravidity 1 parity 0, presented with a fetal heart rate (FHR) of 243 beats per minute during a routine antenatal examination at 31 + 2 wk of gestation. Before termination of pregnancy at 38 wk of gestation, the FHR repeatedly showed serious abnormalities, lasting more than 30 min...

To analyze the differences in risk factors and pregnancy outcomes between recurrent and initial pre-eclampsia(PE) with severe features. Data from recurrent (n = 128) and initial (n = 904) PE with severe features who terminated their pregnancy or gave birth at 20 weeks of gestation or later at the tertiary teaching hospital (Women's Hospital of Nanjing Medical University, Nanjing Women and Children's Healthcare Hospital) from January 2016 to December 2022 were collected. Risk factors for recurrent PE with severe features and differences in pregnancy outcomes between the two groups were assessed using the chi-square test, student t-test, or nonparametric test...

BACKGROUND: Because selective termination (ST) for discordant dichorionic twin anomalies carries a risk of pregnancy loss, deferring the procedure until the third trimester can be considered in settings where it is legal. OBJECTIVE: To determine whether perinatal outcomes were more favorable following deferred rather than immediate ST. STUDY DESIGN: A French multicenter retrospective study from 2012 to 2023 on dichorionic twin pregnancies with ST for fetal conditions which were diagnosed before 24 WG...

OBJECTIVE: To explore the clinical and genetic characteristics of a fetus diagnosed with Congenital myasthenic syndrome type 16 (CMS16). METHODS: A couple who had visited Tianjin Medical University General Hospital in February 2018 due to "adverse outcome of two pregnancies" was selected as the study subject. Clinical data was gathered. Peripheral blood and amniotic fluid samples were collected and subjected to whole exome sequencing (WES). Candidate variant was verified by Sanger sequencing...

Vitamin D is a key regulator of bone mineral homeostasis and may modulate maternal bone health during pregnancy and postpartum. Using previously-collected data from the Maternal Vitamin D for Infant Growth (MDIG) trial in Dhaka, Bangladesh, we aimed to investigate the effects of prenatal and postpartum vitamin D3 supplementation on circulating biomarkers of bone formation and resorption at delivery and 6 months postpartum. MDIG trial participants were randomized to receive a prenatal;postpartum regimen of placebo or vitamin D3 (IU/week) as either 0;0 (Group A), 4200;0 (B), 16,800;0 (C), 28,000;0 (D) or 28,000;28,000 (E) from 17 to 24 weeks' gestation to 6 months postpartum...

We present the case of a 35-year-old pregnant woman who visited our department for a routine ultrasonography screening scan for fetus anatomy during the 22nd week of gestation. Our report revealed a male fetus with marked hydrocephalus and severe intrauterine growth retardation. After extensive counseling, the couple decided to proceed with an invasive diagnosis via amniocentesis. The cytogenetic analysis showed findings related to clinical history and ultrasound findings related to the presence of a nucleotide change in c...

Craniofacial microsomia (CFM) primarily includes specific head and neck anomalies that co-occur more frequently than expected. The anomalies are usually asymmetric and affect craniofacial features; however, there are frequently additional anomalies of variable severity. Published prenatal findings for CFM are limited. This study contributes 11 cases with CFM and their anomalies identified prenatally. Cases born between January 1, 1997 and December 31, 2019 with CFM were abstracted from the Alberta Congenital Anomalies Surveillance System, which is a population-based program ascertaining congenital anomalies for livebirths, stillbirths, and termination of pregnancies for fetal anomalies...

Elle porte notamment sur les analyses de laboratoire parentales, les prophylaxies prénatale et post-partum de routine et les autres indications cliniques de la prophylaxie. La prévention de l'allo-immunisation érythrocytaire pendant la grossesse avec antigènes atypiques (autres que l'antigène D), pour lesquels aucune immunoprophylaxie n'est actuellement offerte n'est pas abordée dans cette directive...

INTRODUCTION: Registries of congenital anomalies (CAs) play a key role in the epidemiological surveillance of CAs. The objective was to estimate the prevalence of CAs and proportions of prenatal diagnosis, terminations of pregnancy for fetal anomaly (TOPFA) and infant mortality in the Paris Registry of Congenital Malformations (remaPAR) over 40 years, from 1981 to 2020. MATERIAL AND METHODS: remaPAR records all births (live births, stillbirths ≥22 weeks of gestation and TOPFA at any gestational age) with CAs detected prenatally until the early neonatal period...

Pregnancy complicated with pulmonary arterial hypertension (PAH) is a severe and dangerous condition for both the mother and the fetus. Pregnancy-specific alterations in the maternal cardiovascular system suggest that PAH in pregnancy may manifest more severe symptoms compared with those in non-pregnant patients. Although most societal guidelines recommend early termination in the case of PAH, some recent data suggests that maternal mortality among patients with PAH is lower than previously observed and suggests if a woman decides to proceed with the pregnancy, she should be counseled about the potential risks of continuing with the pregnancy...

INTRODUCTION: In pediatric kidney patients, where clinical presentation is often not fully developed and renal biopsy too risky or inconclusive, it may be difficult to establish the underlying pathology. In cases such as these, genetic diagnosis may be used to guide the treatment, prognosis and counselling. Given the large number of genes involved in kidney disease, introducing next generation sequencing with extended gene panels as part of the diagnostic algorithm presents a viable solution...
