PURPOSE: In this first of two companion papers, we critically review the evidence recently published in the primary literature, which addresses adverse maternal and neonatal pregnancy outcomes associated with programmed embryo transfer cycles. We next consider whether these pathological pregnancy outcomes might be attributable to traditional risk factors, unknown parental factors, embryo culture, culture duration, or cryopreservation. Finally, in the second companion article, we explore potential etiologies and suggest strategies for prevention...

BACKGROUND: The experience of a neonate hospitalised in the Neonatal Intensive Care Unit (NICU) is an understandably traumatic experience for the parents, especially, for the mothers of neonates. This mental distress resulting from preterm birth and/or NICU hospitalisation can be understood as post-traumatic symptomatology, according to the Diagnostic and Statistical Manual-5 version. The aim of this study is to investigate the impact of the admission of a neonate to the NICU (from any reason) on the development of postpartum post-traumatic stress disorder (PTSD) in a sample of women after cesarean sections...

BACKGROUND: Prenatal bleeding is very dangerous for pregnant women with placenta previa during termination of pregnancy in the mid-trimester. Traditionally, cesarean section or hysterectomy is used to stop bleeding. This study aims to investigate the method for termination of mid-trimester pregnancy with placenta previa, especially emergency uterine artery embolization (UAE) combined with cervical double balloon (CDB). METHODS: A retrospective study was conducted based on 261 cases of mid-pregnancy termination in our hospital, where 34 cases with placenta previa were set as the observation group, and the remaining 227 cases were set as control group...

The study focused on the clinical diagnostic value of color Doppler ultrasound of dangerous placenta previa patients under the guidance of intelligent recognition algorithms. 58 patients with placenta previa and placenta accreta admitted to the hospital for treatment were selected as research subjects. The color Doppler ultrasound under the guidance of intelligent recognition algorithm was compared with the two-dimensional ultrasound for specificity, sensitivity, and accuracy. The color Doppler ultrasound results showed that, of the 58 patients, there were 32 cases of complete placenta previa and 26 cases of incomplete placenta previa, which were consistent with the surgical pathology results...

The consequence of each cesarean section is the uterine scar formation. In some patients, uterine scar after cesarean section heals incompletely and as a result, the uterine niche is formed. Most of the small niches are asymptomatic, but the large cesarean scar niches in nonpregnant women may cause a cesarean scar syndrome, which manifest itself as abnormal uterine bleeding, dysmenorrhea and secondary infertility. Among pregnant women, the presence of large niches may be associated with potentially life-threatening consequences, such as cesarean scar dehiscence and uterine rupture, placenta accreta spectrum disorders, placenta previa, cesarean scar pregnancy...

OBJECTIVES: Risk factors for placenta percreta are placenta previa and prior cesarean delivery. Placenta percreta-induced ruptures at non-cesarean sites are very rare, particularly in the early second trimester. CASE REPORT: A 30-year-old woman with a prior cesarean delivery was brought to our emergency department at 17 weeks' gestation for sudden-onset consciousness loss and generalized convulsions. Hypovolemic shock was identified. Computed tomography scans suggested uterine rupture and massive ascites, r/o hemoperitoneum...

Cesarean scar pregnancy (CSP) is a rare occurrence consisting in the implantation of the embryo within the myometrium of a prior cesarean delivery scar. The CSP could be a dangerous condition for women because of the related complications such as placenta previa or accreta, uterine rupture, and hemorrhage. Therefore, early diagnosis and rapid treatment are crucial. Extrauterine implants or ectopic pregnancy (EP) consists in the implantation of an embryo in a site other than the endometrium of the uterine cavity...

Cesarean scar pregnancy is a potentially dangerous consequence of a previous cesarean delivery. If unrecognized and inadequately managed, it can lead to untoward complications throughout all three trimesters of the pregnancy. The rate of occurrence parallels the mounting rate of cesarean sections. The late consequences of cesarean delivery, such as placenta previa and placenta accrete, were known for a long time. However, it took more than a decade for the obstetric community to make the connection between the cesarean scar pregnancy and the placenta accreta spectrum...

Zinc finger E‑box‑binding homeobox 1 (Zeb1) is a promoter of epithelial‑mesenchymal transformation, which may serve an important role in morbidly adherent placenta (MAP). In the present study, the protein expression levels of Zeb1 were examined in the placenta tissues of 60 patients, including 20 patients with placenta accreta (PA) and 20 patients with placenta previa without PA (UPA) and 20 patients in late pregnancy that delivered by cesarean section (normal). The expression levels of Zeb1, N‑cadherin, vascular endothelial growth factor (VEGF), Tumor necrosis factor‑related apoptosis‑inducing ligand‑receptor 2 (TRAIL‑R2), and tumor necrosis factor‑related apoptosis‑inducing ligand‑receptor 3 (TRAIL‑R3) were higher in PA tissues compared with in normal control tissues...

OBJECTIVE: Placenta accreta is an increasingly prevalent and potentially dangerous complication of pregnancy. Although most studies on the subject have addressed the risk factors for the development of this condition, evidence on maternal and neonatal outcomes for these pregnancies is scarce. The objective of the present study is to compile current evidence with regard to risk factors as well as adverse outcomes associated with placenta accreta. METHODS: We conducted a complete literature review using PubMed, MEDLINE, Cochrane Database Reviews, UptoDate, DocGuide, as well as Google scholar and textbook literature for all articles on placenta accreta, and any one of the following keywords: "risk factors", "maternal outcomes", "neonatal outcomes", "morbidity", and "mortality"...

This prospective cohort study aims to clarify the role of preterm placental calcification in high-risk (i.e., hypertension, diabetes, placenta previa or severe anemia) pregnant women as a predictor of poor uteroplacental blood flow (absent or reverse end-diastolic velocity [AREDV]) and adverse pregnancy outcome. Monthly ultrasound was performed starting at 28 weeks' gestation to establish the diagnosis of Grade III placental calcification, with measurement of Doppler velocimetry in the umbilical vessels at 32 weeks' gestation...

The biology of placental and fetal development suggests that alcohol may play a significant role in increasing the risk of feto-infant morbidity and mortality, but study results are inconsistent and the mechanism remains poorly defined. Previous studies have not examined the risk of placenta-associated syndromes (PASs: defined as the occurrence of either placental abruption, placenta previa, preeclampsia, small for gestational age, preterm, or stillbirth) as a unique entity. Therefore, we sought to examine the relationship between prenatal alcohol use and the risk of PAS among singleton births in the Missouri maternally linked data files covering the period 1989-2005...

Thyrotoxic crisis during pregnancy is a rare condition, but because of the danger it poses for the mother and fetus, every physician should be able to diagnose and treat it. When not recognized or incorrect treated hyperthyroidism, which is not easy to diagnose during pregnancy, is usually the basis for thyrotoxic storm. Serious conditions such as Graves' disease or multinodular goiter have to be distinguished from transient hyperthyroidism. Symptoms, such as: heat intolerance, hyperexia, emesis, tachycardia, increased pulse pressure and emotional liability should be considered cautiously because they are characteristic both for hyperthyroidism and for pregnancy...

Placenta accreta which occurs as a complication of total placenta previa is comparatively rare. And the diagnosis of placenta accreta before the caesarean section (C-section) is difficult. We experienced an extremely difficult anesthesia management of placenta accrete because of critical hemorrhage during C-section. We used self-blood collection device Cell Saver5+ (Haemonetics Japan Ltd, Tokyo) for the massive bleeding of 25,500 ml. The Cell Saver could be used to treat life threatening bleeding in C-section without any side effects, although it is thought that the use of the self-blood collection device during C-section had the danger of the amniotic fluid embolism and fetal red cell ontamination...
