Summary: This study aimed to compare the patterns of estimated fetal weight discordance throughout gestation among normotensive women, women with gestational hypertension, and women with preeclampsia and to evaluate the association between crown-rump length discordance at 11 to 14 weeks of gestation and hypertensive disorders of pregnancy. The study found that fetal weight discordance increased progressively throughout pregnancy in women with gestational hypertension and preeclampsia, while normotensive women did not show this trend. Crown-rump length discordance was associated with an increased risk of preeclampsia, especially early-onset preeclampsia.

Summary: The combination of birth weight discordance (BWD) and gestational age (GA) is a better predictor of adverse neonatal outcomes than BWD alone. For dichorionic twins with BWD greater than 40%, the optimal delivery time is suggested to be at 33-34 weeks of gestation, if there are no immediate delivery indications.

Summary: This population-based cohort study investigated the prevalence, risk factors, and consequences of birth weight discordance (BWD) among same-sex twins. The study identified maternal age, education level, and assisted reproductive technologies (ART) as risk factors for BWD in same-sex twins. Adverse neonatal outcomes were more common among BWD pairs, but ART had a protective effect.

Summary: Understanding the short and long-term outcomes of neonates with bronchopulmonary dysplasia is crucial in neonatal care for low-birth-weight infants. Different criteria for diagnosing BPD may have different associations with long-term outcomes, with the NRN definition showing stronger correlation with poor developmental outcomes. BPD diagnosed by NRN definitions might better identify infants at high risk for neurodevelopmental impairment.

Summary: This retrospective cohort study aimed to compare the rates of small-for-gestational-age infants among twin pregnancies with intertwin growth discordance in the absence of fetal growth restriction with that among twin pregnancies with concordant, normal growth identified by ultrasound between 24 0/7 and 31 6/7 weeks' gestation. The results showed that regardless of chorionicity, twin pregnancies with discordance without fetal growth restriction were nearly twice as likely to develop small-for-gestational-age neonates, deliver earlier in gestation, and experience greater neonatal morbidity than twin pregnancies without discordance. This emphasizes the importance of recognizing intertwin growth discordance in twin pregnancies and provides information on adverse perinatal outcomes.

Summary: The objective of this study was to evaluate the risks of stillbirth and neonatal death in twin pregnancies with different levels of growth discordance and small for gestational age (SGA). The study found that regardless of the level of growth discordance and birth weight, the optimal gestational ages for delivery in both dichorionic and monochorionic twin pregnancies were balanced between 36 0/7-6/7 and 37 0/7-6/7 weeks of gestation.

Summary: There is an increasing recognition of the association between pregnancy complications and the development of chronic diseases later in life. Pregnancy can be seen as a stress test that reveals underlying predispositions to disease. However, healthcare providers lack awareness of these risks. A narrative literature review shows that various pregnancy complications are associated with increased risk of cardiovascular disease, diabetes, venous thromboembolism, chronic kidney disease, postnatal depression, and mental health disorders. It is important to offer counseling and risk reduction advice for women in the postnatal period following a complicated pregnancy. Further research is needed to determine optimal screening intervals for cardiovascular disease and diabetes after a complicated pregnancy.

Summary: The authors combine isolation and sequencing of bacteria from both mothers and infants to investigate microbial strain transfer, particularly in the genus Bifidobacterium. They reveal that strain transfer occurs in almost 50% of dyads, with factors such as vaginal birth and avoidance of intrapartum antibiotics being important. Dual approaches, combining cultivation and metagenomic sequencing, are necessary for a comprehensive understanding of this transfer process.

Summary: This study explored the relationships among maternal well-being during pregnancy, breastfeeding, and the infant gut microbiome. The results showed that maternal well-being during pregnancy was not associated with infant microbial diversity. However, exclusive breastfeeding at discharge from hospital was associated with infant microbial beta diversity, and any breastfeeding at 1 month postpartum was associated with infant microbial alpha diversity, observed species, and beta diversity. Exclusive breastfeeding at 1 month postpartum was also associated with infant alpha diversity and number of observed microbial species.

Summary: A breastfeeding-friendly city is a city that provides an enabling environment to support breastfeeding throughout a child's first 2 years or more. However, there are currently no established indicators for defining a breastfeeding-friendly city. This study identified common criteria such as policy, training & education, skilled breastfeeding support, and physical infrastructure, which could be developed into indicators. Further research is needed to determine the importance of these criteria and how they can be measured.
