Summary: This study aimed to investigate the relationship between maternal sleep-disordered breathing events and fetal well-being. The results showed that episodes of maternal sleep apnea and hypopnea did not cause decelerations in fetal heart rate, despite the presence of risk factors such as maternal obesity. However, fetal heart rate variability increased during these events and returned to baseline levels soon after. There was no evidence that maternal sleep-disordered breathing posed an immediate threat to the near-term fetus.

Summary: There is a link between sleep-disordered breathing (SDB) during pregnancy and/or after delivery with hypertension (HTN) and metabolic syndrome (MS). This study found that an apnea-hypopnea index (AHI) >= 5 during pregnancy was associated with an increased risk of MS, while an oxygen desaturation index (ODI) >= 5 during pregnancy was significantly associated with both HTN and MS. Participants who had persistently elevated AHI and ODI during pregnancy and at 2-7 years after delivery had the highest risk for HTN and MS.

Summary: Sleep-disordered breathing (SDB) has significant cardiovascular and neurological effects, with supplemental oxygen therapy showing mixed results in improving oxygen saturation and apnea severity compared to positive airway pressure therapy. Further research is needed to clarify the optimal dose and duration of nocturnal supplemental oxygen (NSO) and its combination with PAP in improving cardiovascular, sleep, and cognitive outcomes in SDB patients.

Summary: This study examines the distribution of sleep positions during pregnancy and their relationships with sleep onset position, sleep-disordered breathing, and pregnancy outcomes. The results suggest that falling asleep on the left lateral position is more common, while sleeping in the supine position is less prevalent throughout the night. Falling asleep in the supine position is associated with fetal growth restriction and birthweight.

Summary: Maternal sleep disorders and disruptions have negative impacts on fetal neurodevelopment, with higher sleep disordered breathing associated with delayed fetal neuromaturation and increased motor activity. Conversely, less disrupted maternal sleep is linked to higher fetal heart rate variability and coupling-based neuromaturation. The influence of maternal sleep on fetal nervous system development warrants further study and may have lasting effects beyond pregnancy.

Summary: Through analyzing data from previous studies, independent and novel risk factors for late-preterm (28-36 weeks) and term (≥37 weeks) stillbirth were identified, and the development of a risk-prediction model was explored. The results showed that fetal movement changes, poor antenatal care utilization, and the adequacy of care were associated with stillbirth. These findings are valuable in the risk assessment of late-stillbirth.

Summary: Pediatric overweight/obesity is associated with sleep-disordered breathing (SDB), abnormal neurological and cognitive development, and psychiatric problems. This study explored the associations between body mass index (BMI), SDB, psychiatric and cognitive measures, and brain morphometry in children aged 9-11. The findings revealed that BMI and SDB were positively correlated and associated with changes in cortical thickness and volume in specific brain regions. SDB partially mediated the effects of overweight/obesity on brain regions, and BMI and SDB were also related to dimensional psychopathology and cognitive function. Additionally, the impact of obesity and SDB on brain measures, cognitive function, and mental health was greater in girls compared to boys.

Summary: This study evaluated fetal heart rate (FHR) patterns during sleep in pregnancies complicated by preterm fetal growth restriction (FGR) and found that acute FHR events are more common in FGR cases than in pregnancies with normal fetal growth. The study also revealed that sleep-disordered breathing (SDB) is common in pregnancies with FGR, but it is generally mild and does not increase overnight FHR events or have adverse perinatal outcomes.

Summary: This study investigates the relationship between cord blood leptin levels and neonatal and maternal factors. The results show that cord leptin levels are influenced by multiple factors and can be adjusted for normal population variation. Further studies are needed to determine whether monitoring or intervention is necessary for fetuses with polarized leptin levels.

Summary: Women of South Asian ethnicity in Aotearoa NZ have a higher risk of adverse pregnancy outcomes, including placental dysfunction and antepartum haemorrhage compared to NZ European and Maori women. Placental pathology differences were observed among perinatal deaths between 20+0 to 27+6 weeks gestation, with South Asian women more likely to show features of histologic chorioamnionitis and chorionic vasculitis. Metabolic disorders and an associated pro-inflammatory environment may contribute to these differences.
