Fetal growth restriction in early pregnancy increases the risk of adverse pregnancy outcome, which has a significant social and psychological impact on women. There is limited information related to community-based study to evaluate early indicators related to miscarriage. The aim of this study is to examine the relationship between fetal growth restriction, measured by ultrasound crown-rump length (CRL), and subsequent occurrence of miscarriage in pregnant women in rural Bangladesh. The study was conducted within the Maternal and Infant Nutrition Interventions Trial in Matlab (MINIMat study), Bangladesh...

OBJECTIVE: Non-classic congenital adrenal hyperplasia (NCAH) is common among Ashkenazi Jews (1:400). It is associated with various degrees of postnatal virilization, irregular menses and infertility. Therapy of symptomatic subjects consists of physiologic doses of glucocorticoids. The objective of this study was to evaluate the effect of glucocorticoid treatment on fertility and on pregnancy outcome in women with NCAH. DESIGN, SETTING AND PATIENTS: This retrospective study included 75 women diagnosed with NCAH who were followed in our clinic and sought fertility between 2008 and 2015...

Although Radix Paeoniae Alba (RPA) has been ranked as one of the top 6 herbs used frequently to prevent and treat miscarriages clinically, there is no clear evidence regarding its safety in embryonic development. This study aims to evaluate the potential impacts of RPA on embryonic stem cells (ESCs) and pregnant mice. Cytotoxicity assays of the extract were performed in ESCs and 3T3 cells. Pregnant ICR mice were orally treated with RPA extracts at dosages of 0 (G1 group as negative controls), 2, 8 and 32 g/kg/day (G2, G3 and G4 groups) respectively from the gestation day (Gd) 6-15...

Miscarriages affect 15% of clinically recognized pregnancies. Recurrent miscarriage (RM) is defined by the occurrence of at least two consecutive pregnancy losses and affects 1% to 5% of couples trying to conceive. In an attempt to categorize patients with RM and identify the mechanisms leading to their miscarriages, we first used flow cytometry to assess the ploidy of 93 products of conception (POCs) from 53 patients with RM (≥ 3 miscarriages). We identified a single patient with four triploid POCs. We then used fluorescent in situ hybridization to confirm the triploidies and fluorescent microsatellite genotyping with distal and pericentromeric markers to determine their parental origin and the mechanisms leading to their formation...

Air pollution can influence women's reproductive health, specifically menstrual cycle characteristics, oocyte quality, and risk of miscarriage. The aim of the study was to assess whether air pollution can affect the length of the overall menstrual cycle and the length of its phases (follicular and luteal). Municipal ecological monitoring data was used to assess the air pollution exposure during the monitored menstrual cycle of each of 133 woman of reproductive age. Principal component analyses were used to group pollutants (PM10, SO₂, CO, and NOx) to represent a source-related mixture...

The use of nuchal translucency (NT) in 1992 by Nicolaides et al was a major breakthrough in screening for chromosomal aneuploidies at the end of the first trimester. However, pathological conditions other than chromosomal aneuploidies are also associated with increased NT, which can also be detected in normal fetuses. This study sought to evaluate the causes of this ultrasound sign in a group of patients from Iasi, Romania.During the decade-long study period, there were 71 certified cases involving increased NT; the patients in these cases underwent diagnostic amniocentesis and karyotyping...

This paper explores miscarriage in a variety of Qatari contexts to reveal the multiple realities of the unborn. During 18 months of ethnographic research, a range of settings in which fetuses emerged were explored. The unborn are represented and imagined differently, particularly in relation to the ways they are located, with multiple beings emerging according to the context and position of the stakeholder. This paper considers fetuses produced within these contexts and considers how they can be different beings simultaneously...

AbstractToxoplasma gondii infects a broad range of warm-blooded hosts, including humans. Important clinical manifestations include encephalitis in immunocompromised patients as well as miscarriage and fetal damage during early pregnancy. Toxoplasma gondii dense granule antigen 2 and 5 (GRA2 and GRA5) are essential for parasitophorous vacuole development of the parasite. To evaluate the potential of GRA2 and GRA5 as recombinant DNA vaccine candidates, these antigens were cloned into eukaryotic expression vector (pcDNA 3...

PURPOSE: Prior studies suggest that pregnancy outcomes after autologous oocyte cryopreservation are similar to fresh in vitro fertilization (IVF) cycles. It is unknown whether there are differences in pregnancy and perinatal outcomes between cryopreserved oocytes and cryopreserved embryos. METHODS: This is a retrospective cohort study comparing pregnancy and perinatal outcomes between oocyte and embryo cryopreservation at a university-based fertility center. We included 42 patients and 68 embryo transfers in patients who underwent embryo transfer after elective oocyte preservation (frozen oocyte-derived embryo transfer (FOET)) from 2005 to 2015...

Despite extensive studies, there still seems to be uncertainty as to the possible reproductive risk of selective serotonin reuptake inhibitors (SSRIs) and selective serotonin norepinephrine reuptake inhibitors (SNRIs) in pregnancy. We, therefore, assess the current data on the risk/benefit of SSRI use in pregnancy. As the neurodevelopmental effects of SSRIs are discussed in another paper in this issue, we will not address the possible neurodevelopmental effects. Special emphasis is given to the newer, large population-based studies...

BACKGROUND: Mycoplasmas are frequently isolated from the genital tract. New molecular PCR-based methods for the detection of mycoplasmas can better define the real epidemiology of these microorganisms. The aim of this study was to evaluate the prevalence of mycoplasmas in a population of childbearing age women by means of PCR. METHODS: This 21-month multicentre observational study was conducted at four Italian clinical microbiology laboratories. Women reporting symptoms of vaginitis/cervicitis, or with history of infertility, pregnancy, miscarriage or preterm birth were included...

Uterine artery pseudoaneurysm is a rare but potentially life-threatening complication that can occur after various uterine manipulations. A 34-year-old nulliparous patient with a previous history of four consecutive miscarriages with unknown etiologies underwent transmyometrial oocyte retrieval as a result of malpositioning of the right ovary. Six days later, she experienced massive vaginal bleeding after a day of intermittent bleeding and was transferred to our hospital. At triage, continuous bleeding from the cervical canal was observed...

Embryo biopsy has been performed in bovine in vivo produced embryos for the last twenty years, but little could be done with few embryonic cells in the past. Recently, advances in single cell analysis enabled a wide range of applications using embryo biopsy, from morphology to genetics analysis and different omics-techniques, which are promising for in vitro-fertilized (IVF) embryos. The aim of this study was to address if biopsy procedure would affect post implantation development of IVF blastocyts. Here we show that blastocyst stage do not affect re-expansion of biopsied embryos (regular blastocyst: 73...

Successful embryo implantation requires good quality embryo but also needs a receptive endometrium site. In our clinical practice, we daily verify that an adequate endometrial growth is reached for successful implantation. To understand whether platelet rich plasma (PRP) can improve endometrium thickness and performance, PRP treatment was carried out after at least three of the classic medical protocols currently in use had been unsuccessfully adopted. Eight patients with more than 3 cryo-transfers cancelled because of failure of endometrial growth, defined as endometrium less than 6 mm, with negative hysteroscopic screening for endometrial pathology, and with negative bacteriologic screening, before present and all previous treatment, were selected to undergo PRP treatment...

Human leukocyte antigen (HLA)-G plays a crucial role in conferring fetal-maternal tolerance and ensuring a successful pregnancy. CD56(bright) natural killer (NK) cells accumulate at the maternal decidua in large numbers during pregnancy and are found in direct contact with fetal trophoblasts. There are increasing evidences that decidual NK (dNK) cells are crucial for pregnancy. However, the regulation of dNK cells is mostly unknown. Here, we provide evidences that the secretion function of dNK cells in recurrent spontaneous abortion was impaired, which led to the impairment of the proinvasion and proangiogenesis functions of dNK cells...
