Objective To investigate the changes in preterm birth rate,its gestational age distribution,and possible contributors in Peking Union Medical College Hospital (PUMCH) over the last 25-year period. Methods The clinical data of premature deliveries,both singleton and twins,in PUMCH from January 1,1990 to December 31,2014 were retrospectively analyzed. We counted the number of premature fetuses and assessed the changes of preterm birth rate and its gestational age distribution (including extremely preterm birth,early preterm birth,and late preterm birth) over time...

INTRODUCTION: With the advent of assisted reproductive treatment options, the incidence of multiple pregnancies has increased. Although the need for elective single embryo transfer is emphasized time and again, its uniform applicability in practice is yet a distant goal. In view of the fact that triplet and higher order pregnancies are associated with significant fetomaternal complications, the fetal reduction is a commonly used option in such cases. This retrospective study aims to compare the perinatal outcome in patients with triplet gestation who have undergone spontaneous fetal reduction (SFR) as against those in whom multifetal pregnancy reduction (MFPR) was done...

The incidence of multifetal gestations in the United States has increased dramatically over the past several decades. The rate of twin births increased 76% between 1980 and 2009, from 18.9 to 33.3 per 1,000 births (). The rate of triplet and higher-order multifetal gestations increased more than 400% during the 1980s and 1990s, peaking at 193.5 per 100,000 births in 1998, followed by a modest decrease to 153.4 per 100,000 births by 2009 (). The increased incidence in multifetal gestations has been attributed to two main factors: 1) a shift toward an older maternal age at conception, when multifetal gestations are more likely to occur naturally, and 2) an increased use of assisted reproductive technology (ART), which is more likely to result in a multifetal gestation ()...

BACKGROUND: Data regarding the effects of multifetal pregnancy on the incidence of gestational diabetes mellitus (GDM) are inconsistent and even conflicting. Twin pregnancies have been associated with no increase, a marginal increase or a higher incidence of gestational diabetes. In triplet pregnancies, these effects have not been investigated yet. OBJECTIVES: To analyze the results of the glucose challenge and tolerance tests in singleton, twin and triplet pregnancies...

Multifetal pregnancy reduction (MPR) is an accepted method of reducing complications of triplet pregnancies and higher-order multifetal pregnancies. Eighty-three pregnancies that underwent early (68 weeks) transvaginal MPR were compared with 125 pregnancies that underwent late (11-14 weeks) transabdominal MPR. Rates of pregnancy loss, preterm delivery, gestational diabetes and hypertensive disorders were similar among both groups. Early MPR was associated with a lower risk for small for gestational age newborns (6...

INTRODUCTION: Umbilical cord occlusion (UCO) utilizing laser photocoagulation is often not considered an option for selective termination after 20 weeks of gestation due to reported limitations of the procedure because of umbilical cord size. We compared outcomes after laser umbilical cord occlusion (L-UCO) before and after 20 weeks of gestation. MATERIALS AND METHODS: We examined all patients with monochorionic- diamniotic twins and higher-order multiples (monoamniotic excluded) that underwent L-UCO at our facility between 2006 and 2014...

Intrauterine growth restriction (IUGR) is interconnected with developmental programming of lifelong pathophysiology. IUGR is seen in human multifetal pregnancies, with stepwise rises in fetal numbers interfering with placental nutrient delivery. It remains unknown whether fetal blood analyses would reflect fetal nutrition, liver, and excretory function in the last trimester of human or ovine IUGR In an ovine model, we hypothesized that fetal plasma biochemical values would reflect progressive placental, fetal liver, and fetal kidney dysfunction as the number of fetuses per gestation rose...

Over the past decades, the use of assisted reproductive technology (ART) has increased dramatically worldwide and has made pregnancy possible for many infertile couples. Although the perinatal risks that may be associated with ART and ovulation induction are much higher in multifetal gestations, even singletons achieved with ART and ovulation induction may be at higher risk than singletons from naturally occurring pregnancies. However, it remains unclear to what extent these associations might be related to the underlying cause(s) of infertility...

BACKGROUND: Psychological distress has been reported by mothers of infants born very preterm (VPT) and by mothers of multiples (twins and triplets). This study examined the influence of i) multiple birth and ii) bereavement associated with a multifetal pregnancy, on mental health, parenting stress and family functioning for mothers of children born VPT across early childhood. METHODS: Participants were 162 mothers of 194 infants (129 singletons, 65 multiples) born at <30weeks' gestation or with a birth weight<1250g who completed questionnaires when their children were two and seven years corrected age...

INTRODUCTION: A velamentous cord insertion (VCI) describes a peripheral umbilical cord insertion to the placenta with blood vessels from the cord traversing fetal membranes before reaching the placental margin. These vessels remain unprotected and exposed to pressure and injury during pregnancy and labor. OBJECTIVES: To determine the risk factors for VCI, and assess the risk for complications and adverse outcomes of pregnancies with VCI. METHODS: A retrospective cohort study of women who gave birth at Soroka Medical Center between the years 1988 to 2011...

The objective of the present work was the comparative study of the state of the acoustic analayzer in the full-term and premature infants born after multifetal (MP) or singleton (SP) pregnancies with the body weight at birth corresponding to the gestational age (normotrophics) and presenting with intrauterine growth retardation (IUGR). The method of distortion product otoacoustic emissions (DPOAEs) was employed in the study. It has demonstrated that the normotrophic babies born at the gestational age over 34 weeks after singleton pregnancy pass the DPOAEstest significantly more frequently than normotrophics of the same gestational age born after multifetal pregnancy...

BACKGROUND: Single embryo transfer (SET) has been utilized as a strategy to reduce the chance of multifetal gestations in in vitro fertilization (IVF) but lower pregnancy rate remains a concern. Recent studies showed that favorable outcome regarding SET can be achieved by selecting embryos with "more normal" genetic components. We explored the use of rapid array comparative genomic hybridization (aCGH) to select blastocysts for fresh SET and compared with the protocols adopting vitrified (ultrarapidly frozen) embryo transfer cycle...

BACKGROUND: Fetal fibronectin (fFN) is used as a biomarker for preterm delivery. Currently, its use is discouraged if there has been vaginal manipulation in the previous 24 hours. OBJECTIVE: Our objective is to determine if there are differences between fFN results before and after vaginal manipulation in the form of sterile vaginal exam or transvaginal ultrasound. STUDY DESIGN: This was a prospective observational cohort study at a single center of women between 22-33 6/7 weeks at risk for preterm delivery due to: (1) a history of preterm delivery, short cervix, or multifetal gestation; or (2) symptoms of preterm labor...

BACKGROUND: Cervical dilation in the second trimester is associated with a greater than 90% rate of spontaneous preterm birth and a poor perinatal prognosis. OBJECTIVE: To compare the perinatal outcomes of twin pregnancies with dilated cervix in women who underwent either cerclage or expectant management. STUDY DESIGN: Retrospective cohort study of asymptomatic twin pregnancies identified with cervical dilation of ≥1 cm at 16-24 weeks (1997-2014) at 7 institutions...

BACKGROUND: Extremely preterm birth of a live newborn before the limit of viability is rare but contributes uniformly to the infant mortality rate because essentially all cases result in neonatal death. OBJECTIVE: The objective of the study was to quantify racial differences in previable birth and their contribution to infant mortality and to estimate the relative influence of factors associated with live birth occurring before the threshold of viability. STUDY DESIGN: This was a population-based retrospective cohort of all live births in Ohio over a 7 year period, 2006-2012...
