Summary: Using twin-specific charts can reduce unnecessary medical interventions in twin pregnancies by accurately predicting adverse outcomes. Twin charts identify fewer babies as small for gestational age compared to singleton charts, but show a higher percentage of adverse neonatal outcomes in this group.

Summary: The study found that in early pregnancy, maternal age, multiple pregnancies, and folic acid supplement use were positively associated with crown-rump length (CRL), while pre-pregnancy BMI was negatively associated with CRL. Additionally, CRL was found to be negatively associated with fetal size, small for gestational age (SGA), preterm birth, and neonatal intensive care unit (NICU) admission rate, but positively associated with large for gestational age (LGA).

Summary: Birthweight is an important pregnancy indicator, and previous studies have shown that second-born babies tend to be heavier. This study compared birthweight in subsequent singleton pregnancies following a first twin pregnancy versus a first singleton pregnancy. The results indicated that while first twin pregnancies contribute to a greater combined total offspring birthweight, birthweights of subsequent singleton babies were similar regardless of whether the first pregnancy was a twin or singleton.

Summary: This study compared the accuracy of estimating the due date in dichorionic twin pregnancies conceived by assisted reproductive technology using the crown-rump length of the smaller twin versus the larger twin. The results showed that using the crown-rump length of the smaller twin resulted in a more accurate estimation of the due date and a better detection of fetal growth restriction.

Summary: Iron deficiency in utero and infancy can cause irreversible neurocognitive damage, but the burden of neonatal iron deficiency in the United States is unknown. Infants born from twin pregnancies may be at higher risk of inadequate nutrient endowment at birth. This study compared the burden of neonatal iron deficiency in cord blood serum samples from twin and singleton pregnancies.

Summary: Significant shape changes in human facial skeleton occur in early prenatal period, with the growth trajectory following a curved line with three flexion points. Early antero-posterior development leads to a shift from mandibular prognathic to orthognathic appearance, followed by lateral expansion. Development of zygoma and mandibular ramus is closely integrated with masseter muscle during this time.

Summary: This study aimed to compare the accuracy of neonatal transcerebellar diameter (TCD) measurement with first trimester ultrasound (1TUS) in estimating postconceptual gestational age (PCGA). The results showed a high correlation between TCD measurement and 1TUS in PCGA estimation, but TCD generally underestimated gestational age by 4.6 days. Further research is needed to determine the generalizability of this method for estimating PCGA in undated gestations.

Summary: This study evaluated the differences in maternal renal function between singleton and twin pregnancies in the second half of pregnancy. The study included 1711 pregnant women, with 1547 singleton pregnancies and 164 twin pregnancies. The results showed that twin pregnancies had higher serum creatinine levels, lower eGFR, and a higher rate of renal dysfunction compared to singleton pregnancies. Twin pregnancy, nulliparity, and preeclampsia were identified as significant risk factors for maternal renal dysfunction. Monitoring renal function is important in twin pregnancies.

Summary: The purpose of the study was to determine the accuracy of fetal sex determination by ultrasound at 11-14 weeks' gestation. A total of 567 fetuses were assessed, and the angle of the genital tubercle was measured to assign male or female sex. The overall accuracy of fetal sex assignment was 94.4%, with higher accuracy at later gestational ages.

Summary: There is an increased occurrence of cardiovascular diseases in women within 1 to 2 decades after a preeclamptic pregnancy. Recent evidence suggests that the abnormal biochemical and echocardiographic findings in preeclamptic women do not resolve after giving birth. Many women remain hypertensive in the immediate postnatal period, with some showing signs of cardiac dysfunction. Close monitoring and effective blood pressure control in the immediate postnatal period may lead to persistently lower blood pressures in women years after stopping medication. This review emphasizes the importance of delivering effective medical care in the fourth trimester of pregnancy to improve long-term cardiovascular health after a preeclamptic birth.

Summary: Routine mid-gestational uterine artery Doppler can modify the risk for preterm pre-eclampsia after first-trimester combined pre-eclampsia screening. Women at low risk in the first trimester but with high mid-gestational uterine artery Doppler resistance had a higher prevalence of preterm pre-eclampsia. This suggests that pregnancy care should not be de-escalated for women at high risk in the first trimester with low mid-gestational uterine artery Doppler resistance, and escalation of care may be justified for women at low risk but with high mid-gestational uterine artery Doppler resistance.

Summary: This study examines the significance of not meeting Dawes-Redman criteria on computerised cardiotocography in high-risk pregnancies. The results show that the risk of stillbirth is higher in the group that does not meet the criteria, even after excluding cases with low short-term variation. Therefore, pregnancies that do not meet the criteria should be closely monitored.

Summary: The study aimed to evaluate the prenatal ultrasound features associated with operative complications and assess the interobserver agreement of prenatal ultrasound assessment with histopathological confirmation of placenta accreta spectrum (PAS). The results showed moderate agreement between examiners in assessing the low or high probability of PAS based on ultrasound features. Concordant assessment of high probability of PAS was associated with high morbidity and a very high likelihood of histopathologic confirmation.

Summary: This study compared the short-term variation (STV) outputs of a novel self-applied non-invasive fetal electrocardiography (NIFECG) device with those obtained from computerized cardiotocography (cCTG). The study found that, after appropriate filtering, removal of poor-quality traces, and correction for signal loss, NIFECG was able to produce STV values strongly correlated with those of cCTG.

Summary: The study found that there is a correlation between phase-rectified signal averaging (PRSA) and computerized cardiotocography (cCTG), as well as a relationship between PRSA and short-term variation (STV). PRSA may be an equivalent method of fetal assessment to STV and can generate interpretable non-invasive fetal electrocardiography (NIFECG) traces with high accuracy. These findings raise the possibility of self-applied at-home or remote fetal heart-rate monitoring, increasing surveillance in high-risk women without impacting service demand.
