AbstractIn 65 consecutive twin pregnancies, 722 measurement of fetal abdominal circumference have been obtained with ultrasound. Zygosity was established after delivery in 85% of the pregnancies. There was no difference in mean abdominal circumference measurements between monozygotic and dizygotic pregnancies. In both groups, the pattern of growth was linear throughout pregnancy in contrast to that predicted by birth-weight for gestational age charts. It is suggested that increasing trunk flexion, in later twin pregnancy, may distort accurate abdominal circumference measurement.

Introduction: Previous studies demonstrated a continues decline in fetal growth throughout singleton pregnancy after bariatric surgery. However, intrauterine growth in twin pregnancy is subjected to further underlying processes. This study was to investigate the longitudinal assessment of fetal biometry and abdominal fat thickness of twin pregnancies conceived after gastric bypass surgery and compare them to BMI-matched and obese controls. Materials and methods: We retrospectively assessed ultrasound data of 30 women with dichorionic-diamniotic twin pregnancy (11 women after gastric bypass surgery, 9 obese mothers with pregestational BMI ≥ 30 kg/m² and 10 BMI and age matched controls). We assessed fetal growth parameters including fetal subcutaneous adipose tissue thickness (FSCTT) as well as newborn biometry after delivery. Patient characteristics were obtained from the medical records. Results: The rise in FSCTT curves was markedly slower in twin offspring of women with history of gastric bypass as compared to offspring of obese mothers and offspring of BMI matched controls. Hence, FSCTT was significantly decreased in gastric bypass offspring as compared to both control groups at 34 weeks of gestation. Also, growth curves of abdominal circumference were decreased in offspring of gastric bypass patients as compared to obese mothers. Infants of mothers with history of gastric bypass showed significantly lower birth weight percentiles compared to newborns of obese mothers (27.2 vs 48.8 pct, p=0.025). There was no significant difference in inter twin birth weight difference between offspring of gastric bypass (median: 9.9%, IQR: 6.5 to 20.0) vs. obese (median: 14.6%, IQR: 8.2 to 21.6) and BMI matched controls (median: 9.0%, IQR: 6.3 to 12.6, p=0.714). Conclusions: In summary, intrauterine growth delay in twin pregnancies after GB is assumed to be a multifactorial event with altered metabolism as the most important factor. However, special attention must be paid to the particularity of twin pregnancies as they seem to be subject to other additional mechanism.

AbstractA total of 146 twin pregnancies were studied to evaluate the importance of bed rest. A significantly reduced frequency of preterm delivery was found after bed rest in hospital as compared to bed rest at home or no bed rest at all. An increase in gestational age and in birth weight was seen after bed rest. No effect was found on the intrauterine increase of fetal weight per time. Early routine ultrasound is recommended, so that effective bed rest may be instituted in due time.

Abstract:Aim:To investigate the clinical characteristics and outcome of twin pregnancies complicated by single intrauterine death and how to improve the outcomes of surviving twins. Three thousand three hundred and eighty-four women who delivered twin pregnancies at Women’s Hospital, Zhejiang University, School of Medicine were included. Clinical and demographic data on gestational age, etiology, morbidity and mortality for mothers and fetuses were collected.Results:The median gestational age for detecting a single intrauterine death in twin pregnancy was 29 weeks and the average gestational age of pregnancy termination was 32 weeks. At least one complication occurred in 93 of 134 mothers (69.4%). The leading causes of a single intrauterine death were umbilical cord abnormality (21.6%), congenital anomalies (17.9%), twin-twin transfusion syndrome (TTTS) (8.2%) and velamentous placenta (7.4%). Of the 134 cases, in 115 cases the remaining twin survived. The birth weight of the surviving twin was significantly higher in pregnancies that continued for more than 1 week after single intrauterine death compared to that ended within 1 week after intrauterine death.Conclusions:Extension of gestation for the surviving twin fetus as long as possible in ensuring the health of the surviving twin and mother, will improve the prognosis of surviving twin after a single intrauterine death.

Background: Gestational diabetes mellitus represents a metabolically altered fetal environment due to an increased maternal supply of carbohydrates. It leads to fetal hyperinsulinemia and stimulates insulin-sensitive tissue, predominantly of the abdomen, resulting in increased fetal growth and delivering large-for-gestational-age newborns. Implications of fetal hyperinsulinemia reach far beyond delivery. Children of mothers with diabetes in pregnancy are predisposed to develop obesity and glucose intolerance through a non-genetic “fuel-mediated” mechanism. The objective of the present study was to study the “fetal growth pattern at different periods of pregnancy complicated by diabetes” and to identify the factors that influence the fetal growth pattern in pregnancy complicated by diabetesMethods: 69 pregnant women with diabetes and 34 pregnant women without diabetes were included in the study by random sampling. Maternal parameters such as age, parity, height, weight at registration, and weight gain during pregnancy, BMI at the time of registration of pregnancy and at the time of delivery, detailed diabetic profile and management including meal plan, insulin administration and dosage were recorded. The fetuses were monitored for Biparietal diameter, abdomen circumference, femur length by 2 ultrasound examinations, one at 18-22 weeks and another at 28-32 weeks were performed. Soon after delivery, sex, gestational age, birth weight, length, head circumference and chest circumference of the newborn were recorded and infants were classified as LGA/SGA/AGA.Results: Maternal age, parity, BMI at the time of delivery and maternal weight gain had significant influence on the birth weight. The abdominal circumference of the fetus detected at 18-20 and 28-32 ultrasound scans had a very significant correlation with neonatal mean birth weight percentile. Conclusions: Not all babies born to diabetic mothers are macrosomic. SGA babies were not uncommon in pregnancies with diabetes especially in those who did not have significant micro vasculopathy. Maternal nutrition plays a significant key role in determining birth weight of babies even in pregnancies complicated by diabetes.

Abstract Background Locked twins is a rare and hazardous obstetric complication, which occurs in approximately 1:100 twin pregnancies. One of the known etiologic factors for locked twins is size of the twins. We report a case of chin-to-chin locked twins that occurred at gestational age of 30 weeks pus 6 days. Case summary A 27 years-old primigravida Oromo mother presented with a history of pushing down pain and passage of liquor of 6 hours duration at gestational age of 30 weeks plus 6 days. With a diagnosis of twin pregnancy (first twin non-vertex), abdominal delivery was decided in latent first stage of labor but mother refused caesarian delivery and she was allowed to labor with the hope of achieving a vaginal delivery. In second stage, interlocking twin was encountered and a low vertical cesarean section was done to effect delivery of twins without the need to decapitate the first twin. Conclusion Locked twin is a rare obstetric complication. Whenever it is encountered, successful delivery can be achieved without the need to have decapitation of the first twin during caesarian section.

AbstractObjective:To analyze the accuracy of ultrasound prediction of birth weight discordance (BWD) and the influence of chorionicity and fetal growth restriction (FGR) on ultrasound performance.Methods:Retrospective analysis of 176 twin pregnancies at a Portuguese tertiary center, between 2008 and 2014. Last ultrasound biometry was recorded. Cases with delivery before 24 weeks, fetal malformations, interval between last ultrasound and deliver >3 weeks, twin-to-twin transfusion syndrome and monoamniotic pregnancies were excluded. The accuracy of prediction of BWD was assessed using the area under the receiver-operating characteristics curve (AUC).Results:BWD ≥20% was present in 21.6% of twin pregnancies. EBW had the best predictive performance for BWD (AUC 0.838, 95%CI 0.760–0.916), with a negative predictive value of 86.9% and a positive predictive value of 51.3%. Chorionicity did not influence ultrasound performance. None of the biometric variables analyzed was predictive of BWD in pregnancies without FGR.Conclusion:The accuracy of ultrasound in the prediction of BWD is limited, particularly in pregnancies without fetal growth restriction. Clinical decisions should not rely on BWD alone.

Twin pregnancies are commonly assessed using singleton growth and birth weight reference charts. This practice has led to a significant number of twins labelled as small for gestational age (SGA), causing unnecessary interventions and increased risk of iatrogenic preterm birth. However, the use of twin-specific charts remains controversial. This study aims to assess whether twin-specific estimated fetal weight (EFW) and birth weight (BW) charts are more predictive of adverse outcomes compared to singleton charts. Centiles of EFW and BW were calculated using previously published singleton and twin charts. Categorical data were compared using Chi-square or McNemar tests. The study included 1740 twin pregnancies, with the following perinatal adverse outcomes recorded: perinatal death, preterm birth <34 weeks, hypertensive disorders of pregnancy (HDP) and admissions to the neonatal unit (NNU). Twin-specific charts identified prenatally and postnatally a smaller proportion of infants as SGA compared to singleton charts. However, twin charts showed a higher percentage of adverse neonatal outcomes in SGA infants than singleton charts. For example, perinatal death (SGA 7.2% vs. appropriate for gestational age (AGA) 2%, p < 0.0001), preterm birth <34 weeks (SGA 42.1% vs. AGA 16.4%, p < 0.0001), HDP (SGA 21.2% vs. AGA 13.5%, p = 0.015) and NNU admissions (SGA 69% vs. AGA 24%, p < 0.0001), when compared to singleton charts (perinatal death: SGA 2% vs. AGA 1%, p = 0.029), preterm birth <34 weeks: (SGA 20.6% vs. AGA 17.4%, p = 0.020), NNU admission: (SGA 34.5% vs. AGA 23.9%, p < 0.000). There was no significant association between HDP and SGA using the singleton charts (p = 0.696). In SGA infants, according to the twin charts, the incidence of abnormal umbilical artery Doppler was significantly more common than in SGA using the singleton chart (27.0% vs. 8.1%, p < 0.001). In conclusion, singleton charts misclassify a large number of twins as at risk of fetal growth restriction. The evidence suggests that the following twin-specific charts could reduce unnecessary medical interventions prenatally and postnatally.

Objectives: To evaluate maternal and neonatal complications and pregnancy outcomes of twin pregnancies. Methods: The cross sectional study was conducted using retrospective data on the twin pregnancies with more than 28 weeks of gestational age. The study used data over a period of five years, from March 10, 2010 to March 9, 2015 in the Department of Obstetrics and Gynecology, GMC Teaching Hospital Pokhara. Results: Of the 50 twin pregnancies, the most common maternal complication was preterm delivery (40%). Other maternal complications were anemia (36%), pregnancy induced hypertension (14%), premature rupture of membranes (14%), postpartum hemorrhage (12%) and antepartum hemorrhage (6%). Median gestational age at delivery was 37 weeks. Most common route of delivery was cesarean section (66%). Most common neonatal complication was low birth weight (48%) births first twin and second twin 56%. Conclusion: Twin pregnancy has high maternal and neonatal complications, especially preterm delivery that increases the risk of significant neonatal morbidity and mortality.

Abstract Context: A common polymorphism in the GH receptor (GHR) gene has been linked to increased growth response in GH-treated patients. No former study has focused on the association to prenatal growth. Objective: The aim of the study was to evaluate the association between the d3-GHR isoforms and spontaneous pre- and postnatal growth. Design: A prospective study was conducted on third-trimester fetal growth velocity (FGV), birth weight, birth length, and postnatal growth. Setting: The study was conducted at Copenhagen University Hospital. Participants: A total of 115 healthy adolescents were divided into those born small for gestational age (SGA) and appropriate for gestational age with or without intrauterine growth restriction. Main Outcome Measures: FGV was measured by serial ultrasonography, birth weight, birth length, and adolescent height. Isoforms of the d3-GHR gene (fl/fl, d3/fl, and d3/d3) were determined. Results: The prevalence of the d3-GHR isoforms was 50% but differed among the groups (P = 0.006), with a high prevalence (88%) in the group born SGA with verified intrauterine growth restriction. The d3-GRH allele were associated with decreased third-trimester FGV (P = 0.05) in SGA subjects. In the entire cohort, carriers of the d3-GHR allele had a significantly increased height (−0.10 vs. 0.34 sd score; P = 0.017) and change in height from birth to adolescence compared with carriers of the full-length GHR allele (0.57 vs. −0.02 sd score; P = 0.005). Conclusions: This study showed an increased spontaneous postnatal growth velocity in the carriers of the d3-GHR allele. Interestingly, we found the opposite effect on prenatal growth in the SGA group, with a decreased FGV in carriers of the d3-GHR allele.
