Background: Postpartum bilateral femoral neck fracture (BFNF) is a rare condition. We here report a case of BFNF due to excessive corticosteroid consumption, twin pregnancy, immobility, and vitamin D deficiency. Case: This is a report of a 32-yr-old woman with bilateral femoral insufficiency fracture five days after emergency cesarean section due to preterm labor, twin pregnancy, and the history of a previous cesarean section at 33 wk. Antenatal repeated courses of betamethasone injections for fetal lung maturity, daily oral use of prednisolone for the history of miscarriage, immobilization, and vitamin D deficiency were the important contributing factors in her past medical history and lab investigations...

Twin Reverse Arterial Perfusion (TRAP) Sequence is a rare complication of monochorionic pregnancies. Without intervention, the viable pump twin in a case of TRAP Sequence may develop high output cardiac failure leading to an intrauterine fetal demise. We present 3 cases of TRAP Sequence pregnancy diagnosed during the second or third trimesters of pregnancy. There are minimal sonographic tools for the guidance of a fetal therapeutic interventional procedure during the second trimester or timing of delivery during the third trimester to reduce morbidity and mortality of a viable fetus...

A total of twenty-four healthy twin-bearing Liuyang black goats were allocated to two trials. In Trial 1, twelve goats received either the control diet (CG, n 6, 100 % feed) or restricted diet (RG, n 6, 60 % feed of CG) from gestation days 26 to 65 after synchronisation. In Trial 2, the remaining goats were randomly and equally divided into two treatments: CG and RG from days 95 to 125 of gestation. Placental traits, fetal weight, serum parameters, nitric oxide (NO), angiogenesis gene expression and cotyledon proteome were measured at the end of each trial...

Prevention of metabolic diseases in small ruminants may improve production efficiency and profitability, yet ewes carrying multiples or who are in poor body condition are at increased susceptibility to develop ketosis. This study evaluated the hand-held Nova Vet Meter to accurately detect β-hydroxybutyric acid (BHBA) concentrations in ewes and determined the percentage of ewes at moderate (0.8 to 1.5 mmol/L BHBA) and greatest (≥1.6 mmol/L BHBA) risk to develop ketosis during late gestation. To validate the Nova Vet Meter, BHBA concentrations of 104 paired blood samples were measured using the Nova Vet Meter and gold-standard laboratory analysis...

OBJECTIVE: Pregnancy after an embryo transfer depends largely on embryo quality, endometrial receptivity, and the technique used in the embryo transfer. Embryo transfers have been reported as inevitably traumatic and difficult for 5-7% of patients in assisted reproduction treatment. In these cases, transmyometrial embryo transfer should be considered as a suitable method to overcome difficult embryo transfers. The aim of this study was to report our experience with this technique and analyze its causes, results and complications...

Body-stalk anomaly is a sporadic and rare maldevelopment disorder characterised by large abdominal wall defect, spinal deformity and rudimentary umbilical cord. It is considered a lethal condition as there are only few reports of survival but there was at least one case of long-term survival after neonatal surgery.Differential diagnosis includes isolated omphalocele or gastroschisis, short umbilical cord, amniotic band, limb body-wall complex and other polymalformative syndromes.There are few reports about the expectant prenatal management of the body stalk anomaly as the majority of prenatal diagnosed cases undergo early elective termination...

Objective: To study the variations and influencing factors of serum triglycerides and cholesterol levels during pregnancy and postpartum. Methods: A retrospective study was performed among 5 020 healthy singleton (95.10%, 4 774/5 020) and twin (4.90%, 246/5 020) women who had delivery in Women's Hospital, Zhejiang University School of Medicine from January 2011 to December 2016. Serum triglycerides and cholesterol levels during pregnancy and postpartum of all the cases were collected. Both singleton and twin pregnant women were divided into advanced age and appropriate age groups, and then data of serum sample were assigned to 3 groups according to the gestation weeks, which were second trimester pregnancy (24-28 gestation weeks) , third trimester pregnancy (32-41 gestation weeks) and postpartum (within 72 hours after delivery) ...

One of the confounders in noninvasive prenatal testing (NIPT) is the vanishing twin phenomenon. Prolonged contribution to the maternal Cell-free DNA (cfDNA) pool by cytotrophoblasts representing a demised, aneuploid cotwin may lead to a false-positive outcome for a normal, viable twin. We show that a vanishing trisomy-14 twin contributes to cfDNA for more than 2 weeks after demise.

OBJECTIVE: To estimate the rate of delivery of the nonpresenting twin first and to identify risk factors for such an event by using a cohort of opposite-sex twins for whom the intrauterine order was well documented with ultrasonography before delivery. METHODS: We conducted a retrospective cohort study of all opposite-sex dichorionic twins in a single tertiary center between 2002 and 2016. Reports of ultrasonograms performed less than 2 weeks before birth were reviewed for information on twins' presenting order in relation to fetal sex...

Commercial application of reproductive biotechnologies such as multiple ovulation and embryo transfer depends on its overall efficiency. Sheep embryo transfer is gradually gaining wider adoption, but pregnancy rates after embryo transfer remain lower than those derived from natural mating for most breeds. The work was aimed to evaluate embryonic and fetal losses in Santa Inês ewes carrying twin pregnancies by natural mating or embryo transfer. Ewes were subjected to synchronized natural mating by ram effect or used as recipients for embryo transfer...

OBJECTIVE: To compare perinatal outcomes between acute single fetal demise following FLP to planned selective reduction (SR) in complicated monochorionic (MC) twin pregnancies. METHODS: This was a secondary analysis of prospectively collected data in complicated MC twin pregnancies from two fetal centers from 2011-2016. Group 1 included women undergoing FLP for TTTS who experienced a single fetal demise within 24 hours of the procedure. Group 2 consisted of women undergoing planned SR with TTTS, and Group 3 SR for indications other than TTTS...

Aberrant fetal growth is associated with morbidities and mortality during childhood and adult life. Although genetic and environmental factors are known to influence in utero growth, their relative contributions over pregnancy is unknown. We estimated, across gestation, the genetic heritability, contribution of shared environment, and genetic correlations of fetal growth measures (abdominal circumference (AC), humerus length (HL), femur length (FL), and estimated fetal weight (EFW)) in a prospective cohort of dichorionic twin gestations recruited through the NICHD Fetal Growth Studies...

Introduction: The prevalence of major congenital anomalies (CAs) shows wide variations depending on geographical location and may range from <1% to 8% and it causes between 20% and 30% of perinatal deaths. In Nigeria, the prevalence of CAs may be underestimated with the general reliance on mostly livebirths ranging between 0.5% and 2.8% exempting cases of miscarriage and abortions. The purpose of this study was to determine the epidemiologic pattern and outcome of major CAs detected prenatally at the University College Hospital, Ibadan, Nigeria, over a 4-year period...

Twin pregnancies discordant for neural tube defects (NTD) is a management dilemma. Risks of preterm delivery from polyhydramnios must be balanced with the risks of selective termination (ST) of the anomalous fetus. We investigated the prevalence of twin pregnancies discordant for NTD and the rate of pregnancy complications in our institution over a 10-year period. Cases were obtained by searching the hospital ultrasound database and findings were confirmed by expert review of ultrasound images. Outcomes of ST and expectant management were assessed...
