Adult survivors of childhood cancers are more prone to developing poor reproductive and obstetrical outcomes than their siblings and the general population as a result of previous exposure to chemotherapy and radiation during childhood. Chemotherapy drugs exert cytotoxic effects systemically and therefore can damage the ovaries, leading to infertility, premature ovarian failure, and, to a lesser extent, spontaneous abortions. They have very limited or no deleterious effects on the uterus that can be recognized clinically...

REVIEW
Rui-Qi Chang, Da-Jin Li, Ming-Qing Li
The survival of allogeneic fetus during pregnancy contradicts the laws of immune responses. Behind this paradoxical phenomenon, the mechanism is quite complex. Indoleamine-2,3-dioxygenase (IDO) is the first and rate-limiting enzyme of tryptophan catabolism. Emerging evidence shows that IDO is expressed at the maternal-fetal interface, including trophoblast cells, decidual stroma cells, decidual immune cells (eg, natural killer cells, T cells, and macrophages), and vascular endothelial cells of decidua and chorion...

OBJECTIVES: To assess adverse fetal outcomes following the administration of H1N1 pandemic vaccination during pregnancy. SEARCH STRATEGY: PubMed, Embase, and Cochrane Library were searched up to January 2017. SELECTION CRITERIA: Cohort studies investigating fetal outcomes after H1N1 influenza vaccination during pregnancy were eligible...

Currently no recommendation exists to collect genital culture for Chlamydia trachomatis and Neisseria gonorrhoeae at diagnosis of spontaneous abortion. A retrospective cross sectional study was performed to identify first trimester abortions with concurrent genital culture collection in an emergency room setting. The results were compared to most current 2015 Center for Disease Control (CDC) statistics. Among women aged 15-24 the rate of C. trachomatis was increased to 20.0% and greater than CDC rate of 6.7% (RR 2...

BACKGROUND: Abortion, spontaneous or induced, is a common complication of pregnancy and exploration of available and safe regimens for medical abortion in developing countries seems crucial. AIMS: The present study was aimed to assess the effect of letrozole in combination with misoprostol in women eligible for legal therapeutic abortion with gestational age ≤14weeks. MATERIALS AND METHODS: This clinical randomized trial was conducted on 78 women who were candidate of medical abortion and eligible for legal abortion with gestational age ≤14 weeks that were randomly divided into two groups of case and controls...

Zika virus (ZIKV) infection during pregnancy in humans results in intrauterine growth restriction, spontaneous abortion, and microcephaly. Here, we found that fetus-derived type I interferon (IFN-I) signaling can enhance anti-ZIKV responses and provide clinical benefits to the fetus. Because IFN-λ shares signaling cascades and antiviral functions with IFN-I, we investigated the in vivo effects of IFN-λ in ZIKV-infected pregnant mice. IFN-λ administration during mid-pregnancy reduced ZIKV burden in maternal and fetal organs and alleviated placental injuries and fetal demise...

OBJECTIVE: This study aims to investigate the presence of Cytomegalovirus (CMV), herpes virus simplex (HSV), and parvovirus B19 (PVB19) in the placental tissue of patients who underwent abortions without an otherwise-defined aetiology. STUDY DESIGN: This cross-sectional study was conducted in a high-risk obstetric maternity facility at a University Hospital in Belo Horizonte, Brazil, from January 2013 to December 2015. We included placenta samples obtained from spontaneous abortions of unknown aetiology...

Hepatitis E virus (HEV) is endemic in Pakistan. Although otherwise asymptomatic, HEV infection becomes fatal in pregnancy, with considerable maternal and fetal morbidity and mortality. We conducted a descriptive study from April to October 2015 in 10 tertiary care hospitals throughout Pakistan to determine maternal and fetal morbidity and mortality in HEV-positive pregnant women with acute jaundice or raised liver function tests. Twenty-one of 135 women were HEV positive and in 3rd trimester except for 1 in 1st trimester...

Primary Zika virus (ZIKV) infections that occur during pregnancy can cause spontaneous abortion and profoundly disrupt fetal development. While the full range of developmental abnormalities associated with congenital Zika syndrome is not yet known, severe cases of the syndrome can present with microcephaly, extensive neurologic and ocular damage, and pronounced joint malformations. Animal models that accurately recapitulate congenital Zika syndrome are urgently needed for vaccine development and for the study of ZIKV pathogenesis...

Breast cancer is the most commonly diagnosed type of cancer among women worldwide. The majority of breast cancers are sporadic and the etiology is not well understood. Several factors have been attributed to altering the risk of breast cancer. A full-term pregnancy is a crucial factor in altering the risk. Early full-term pregnancy has been shown to reduce the lifetime risk of breast cancer, while a later first full-term pregnancy increases breast cancer risk. Epidemiological and experimental data demonstrate that spontaneous or induced abortions do not significantly alter the risk of breast cancer...

BACKGROUND: Miscarriage is a common complication in pregnancy and there is still a lack of biomarkers usable in asymptomatic patients before the event occurs. Periostin (PER), whose levels rise particularly during injury or inflammation, has been shown to play an important local role in implantation and early embryonic development. As PER has been described as a biomarker in various medical conditions we intended to evaluate if changes in PER serum levels may help to identify women at risk for spontaneous abortion in the first trimester...

In mammalian females, diploid somatic cells contain two X chromosomes, one of which is transcriptionally silenced, in a process termed X chromosome inactivation (XCI). While XCI is largely random in placental females, many women exhibit skewed XCI (SXCI), in which the vast majority cells have the same X chromosome inactivated. SXCI has serious health consequences, associated with conditions ranging from Alzheimer's to various autoimmune disorders. SXCI is also associated with outcomes of pregnancies, with higher rates of recurrent spontaneous abortion in women with SXCI...

BACKGROUND: Pregnancy with intrauterine device in place is rare and there are limited data that exist regarding associated perinatal outcomes. OBJECTIVE: The objective of this study is to determine the association between presence of an intrauterine device during pregnancy and spontaneous abortion, induced abortion, and preterm or small for gestational age delivery outcomes.

Almost 1600 individuals from the Polish population were recruited to this study. Among them 319 were fertile couples, 289 were recurrent spontaneous abortion (RSA) couples, and 131 were in the group of recurrent implantation failure (RIF) following in vitro fertilization. The aim of this study was to evaluate the MTHFR c.c.677 C>T and c.c.1298 A>C polymorphisms' association with RSA and RIF. We used PCR-RFLP with HinfI (677 C>T) and MboII (1298 A>C) digestion. We observed a protective effect of the female AC genotype (OR = 0...

INTRODUCTION: Spontaneous abortion (SA) is a common complication of pregnancy. Presence of lupus anticoagulant (LA), one of the antiphospholipid antibodies, has been associated with SA in many studies, especially in Caucasians. This study was carried out to determine the prevalence of LA in women with SA in ABUTH, Zaria. MATERIALS AND METHODS: A cohort of 100 consecutive women presenting with SA with no history of thrombotic episodes were enrolled into the study...

AIMS: This study was aimed to explore the interaction between environment and CD28/B7 pathway to provide the potential epidemiology for prevention and treatment of recurrent spontaneous abortion (RSA). METHODS: The retrospective study included 630 RSA cases and 1320 healthy women during their middle and late prenatal care. Their living environment was investigated, and the influence of environmental factors on pregnancy abortion was analyzed. The genomic DNAs were extracted from the study subjects, and the polymorphisms of CD28 and B7 were analyzed...

Environmental contamination with CrVI is a growing problem both in the U.S and developing countries. CrVI is widely used in numerous industries. Environmental exposure to hexavalent chromium (CrVI) adversely affects pregnancy outcomes and subsequent health of two generations, resulting in higher pregnancy loss, spontaneous abortion and low birth rate. Pregnant women exposed to CrVI through occupational settings experience increased risk of spontaneous abortion, stillbirth, preterm birth, and neonatal death...
