OBJECTIVE: While placental abruption is often associated with short-term adverse pregnancy outcomes, we sought to assess whether placental abruption increases the risk for long-term cardiovascular morbidity of the offspring. METHODS: To study the long-term cardiovascular hospitalizations of offspring of patients with and without placental abruption, cardiovascular morbidity was assessed up to the age of 18 years according to a predefined set of ICD-9 codes associated with hospitalization of the offspring...

The multifetal reduction (MFR) procedure is usually reserved for high-order multiple pregnancies, and aspirated tissues are typically discarded. In this study, cells obtained from MFR tissue (termed multifetal reduction embryonic cells (MFR-ECs)), were characterized in vitro by genotypic and phenotypic analyses and tested in vivo by injection under the kidney capsule of nude mice. MFR-ECs were highly proliferative in culture and showed a normal karyotype by microarray CGH. Immunohistochemical analysis at day zero showed positive focal staining for desmin, S-100 protein, synaptophysin and chromogranin...

BACKGROUND: Pregnancies in the fifth and sixth decades of life have been increasing, but current data are limited regarding the outcomes of twin compared with singleton pregnancies in this age group and to twin pregnancies at younger age. OBJECTIVE: To compare obstetrical and neonatal outcomes of IVF conceived pregnancies, in twin gestations of women who were ≥45 years old at delivery to singletons at similar age and twin gestations at the age of <35 years, and to assess if the complications are mainly influenced by the very advanced maternal age or by the multifetal pregnancy...

PROBLEM: The influence of fetal sex on immune responses in multifetal pregnancies remains incompletely elucidated. The a2 isoform of vacuolar adenosine triphosphatase (a2V) is expressed on the cell membrane of maternal lymphoid cells and contributes to down regulation of pro-inflammatory immune responses during gestation. The association between fetal sex and a2V expression on peripheral blood mononuclear cells (PBMCs) from mothers with twin gestations was assessed. METHOD OF STUDY: Patients in this prospective study were 93 women with twin pregnancies in their mid second or early third trimester- 27 with two male, 30 with two female and 36 with one male and one female fetus...

BACKGROUND: Vitamin D status is hypothesised to play a role in gestational glucose control. No studies to date have examined vitamin D in relation to changes in blood glucose in pregnancy. Thus, the aim was to examine if vitamin D in early pregnancy and vitamin D trajectory associate with blood glucose trajectory over pregnancy in a Swedish cohort. We also investigated the relation between maternal vitamin D status and excessive fetal growth. METHODS: In 2013-2014, pregnant women were recruited to the GraviD cohort study when registering at the antenatal clinics in south-west Sweden...

Given the higher risk of developing imprinting disorders in assisted reproductive technology (ART)-conceived children, we hypothesized that ART may affect DNA methylation of the insulin-like growth factor 2 (IGF2), H19, small nuclear ribonucleoprotein polypeptide N (SNRPN) differentially methylated regions (DMRs) at the fetal stage, which in turn may be associated with sperm abnormalities. A total of 4 patient groups were recruited, namely, multifetal reduction following in vitro fertilization (IVF)/ intracytoplasmic sperm injection (ICSI; n = 56), multifetal reduction following controlled ovarian hyperstimulation (COH; n = 42), male patients with normal semen parameters denoted as normozoospermia group (NZ) for IVF (n = 36), and male patients presenting with asthenozoospermia (OAZ) for ICSI (n = 38)...

The incidence of multiple pregnancy has significantly increased over the past decades, reaching different statistics to double, triple, or even overcome these numerical orders globally. Zygosity and chorionicity are the key elements in the multiple pregnancy but the placentation issue should be correlated primarily with zygosity, unlike chorionicity that should be correlated with the outcome and complications of multifetal gestation. Multiple pregnancy is by itself a special maternal-fetal condition, and the monochorionic one, moreover, due to specific complications...

A 35-year-old woman with membranoproliferative glomerulonephritis type I had quintuplet gestation after induced ovulation. Her serum creatinine level and estimated glomerular filtration rate were 0.86 mg/dL and 61.5 mL/min/1.73 m2 before pregnancy. Blood pressure was normal and urinary protein to creatinine ratio was 0.2 g/gCr. Prednisolone 10 mg on alternate-day administration was continued during pregnancy. At 10 weeks of gestation transvaginal selective embryo reduction was performed and five embryos were reduced to twins...

INTRODUCTION: Previous reports have shown that suboptimal antenatal corticosteroids administration occurs in most cases. However, as multifetal gestations were either excluded or constituted a small proportion of the participants in these studies, little is known about the patterns of use of antenatal corticosteroids in twin pregnancies. MATERIAL AND METHODS: We reviewed the records of women who received antenatal corticosteroids and delivered between 240/7 and 346/7 weeks of gestation during 2015-2017 at 2 university hospitals...

Background: Higher-order multiple (HOM) pregnancies are associated with increased incidences of pregnancy complications mainly abortions, pre-eclampsia, preterm delivery and fetal death. Multifetal reduction (MFR) during first trimester and subsequent delivery of twins can reduce pregnancy associated morbidities. This study was conducted to evaluate the maternal and fetal outcomes of MFR procedure in patients with HOMs those managed in a tertiary care hospital. Methods and Material: It was a prospective observational study carried out in a tertiary care military hospital, India, and all women with higher-order multiples (triplets or more) conceived spontaneously or after infertility treatment (ovulation induction, intra-uterine insemination, or in vitro fertilization) during the 3-year period from Jan 2014 to Dec 2016 were included for MFR...

Low-dose aspirin has been used during pregnancy, most commonly to prevent or delay the onset of preeclampsia. The American College of Obstetricians and Gynecologists issued the Hypertension in Pregnancy Task Force Report recommending daily low-dose aspirin beginning in the late first trimester for women with a history of early-onset preeclampsia and preterm delivery at less than 34 0/7 weeks of gestation, or for women with more than one prior pregnancy complicated by preeclampsia. The U.S. Preventive Services Task Force published a similar guideline, although the list of indications for low-dose aspirin use was more expansive...

We describe a paramedian cleft of the lower lip that cannot be explained by embryological development in a child with only one predisposing factor, which was fetal reduction for a multiple pregnancy. To the best of our knowledge, there has been no report of a cleft that has been induced by the reduction of a multifetal pregnancy.

Throughout most of the 20th century, the risk of maternal mortality in high resource countries decreased dramatically; however, this trend recently has stalled in the United States and appears to have reversed. Equally alarming is that for every reported maternal death, there are numerous severe maternal morbidities or near misses. Shifting maternal demographics (eg, obesity, advanced maternal age, multifetal pregnancies), with attendant significant medical comorbidities (eg, hypertension, diabetes, cardiac disease) and the increase in cesarean deliveries significantly contribute to increased maternal morbidity and mortality...
