Summary: The study found that objectively measured SDB during pregnancy was not associated with an increased risk of large-for-gestational-age (LGA) or small-for-gestational-age (SGA) birthweight. However, certain measures of nocturnal hypoxemia were associated with an increase in LGA risk, independent of BMI.

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: Obstructive sleep apnea (OSA) is a common condition with significant neurocognitive and cardiovascular effects. Positive airway pressure (PAP) therapy can help prevent airway collapse and improve oxygen levels, carbon dioxide levels, and sleep quality. While adherence to PAP therapy was once seen as a barrier, in reality, adherence rates are likely higher than commonly believed, with various strategies available to help improve patient adherence.

Summary: In this study, researchers identified 20 metabolites related to sleep disordered breathing (SDB) using gas chromatography-mass spectrometry analysis. These metabolites were found to be closely related to fructose metabolism. Further analysis revealed that moderate-severe SDB was a significant factor for increased plasma fructose levels, and CPAP treatment can lower plasma fructose levels.

Summary: Heart failure with preserved ejection fraction (HFpEF) is a widespread disease with high morbidity and mortality, and sleep-disordered breathing (SDB) has been found to be closely associated with the development and progression of the obese HFpEF phenotype. Individualized therapeutic strategies and novel technologies like single-cell transcriptomics or CRISPR-Cas9 gene editing are needed to improve treatment outcomes.

Summary: This study investigated the association between typical symptoms of obstructive sleep apnea, daytime somatic arousal, and the apnea-hypopnea index. The findings suggest that there is a relationship between sleepiness, fatigue, and somatic arousal in individuals with sleep apnea. The apnea-hypopnea index and the body sensation questionnaire (BSQ) both independently correlate with sleepiness, with the apnea-hypopnea index impacting sleepiness when it exceeds 50/h.

Summary: Sleep disordered breathing (SDB) is common but often undiagnosed in stroke patients. Screening questionnaires and portable sleep testing (PST) can help expedite the diagnosis and management of SDB in acute stroke, subarachnoid hemorrhage, or transient ischemic attack patients. The STOP-BANG questionnaire showed the highest sensitivity for at least mild SDB, but with low specificity, and overall discrimination of the questionnaires was poor. Inpatient PSTs were found useful for early screening and further outpatient evaluations of SDB.

Summary: Excessive daytime sleepiness in pregnant women may be associated with sleep disordered breathing and adverse obstetric and neonatal outcomes. This study used the Epworth questionnaire and ultrasound examination to assess sleep propensity in pregnant women and found an increase in ESS scores across gestation. However, in low risk pregnancies, ESS scores during pregnancy were not correlated with fetal Doppler parameters, but only with higher birth weight.

Summary: This study aimed to identify the cumulative incidence and predictors of surgical site infection in women with a pre-pregnancy BMI >= 30 kg/m(2) who gave birth by elective CS. The results showed that higher BMI, multiple previous pregnancies, and lack of pre-CS vaginal cleansing were associated with increased risk of SSI. These findings could help in counseling and decision-making for planned elective CS in women with higher pre-pregnancy BMI.

Summary: This study aimed to investigate key antecedents of moderate and severe hypoxic ischaemic encephalopathy (HIE) in newborns. The study found that nulliparity, type 1 diabetes mellitus, and maternal intensive care unit admission were associated with increased odds of moderate/severe HIE. Intrapartum risk factors included emergency caesarean birth, intrapartum haemorrhage, and intrapartum sentinel events. Neonatal risk factors included male sex, late preterm gestation, low Apgar score, severe respiratory distress, and severe acidosis at birth.

Summary: The aim of this study was to evaluate the association of a low cerebroplacental ratio (CPR) with hypoxic ischaemic encephalopathy (HIE), severe neonatal morbidity (SNM) and perinatal mortality (PNM). The study found that a low CPR was significantly associated with SNM, but not with HIE or PNM. These findings have important implications for the clinical management of infants.

Summary: This study assessed the cost-effectiveness of closed incision negative pressure wound therapy (ci-NPWT) compared to standard dressings for preventing surgical site infections (SSIs) in obese women undergoing caesarean section (CS). The results showed that although ci-NPWT can reduce the occurrence of SSIs in obese women, it is associated with higher costs and does not improve quality of life. Therefore, routine use of ci-NPWT for preventing SSIs in obese women undergoing CS is currently not recommended.

Summary: Fetal growth restriction (FGR) leading to low birth weight (LBW) is a major cause of neonatal morbidity and mortality worldwide. Failure in normal placental development leads to placental dysfunction and related placental diseases. Early recognition of at-risk pregnancies and the development of screening tests based on maternal biomarkers can potentially prevent adverse maternal and perinatal outcomes. Among the current biomarkers, placental growth factor and soluble fms-like tyrosine kinase 1 show promise for predicting FGR and placental dysfunction.

Summary: Using shotgun metagenomic sequencing, the researchers assessed the microbes present in expressed breastmilk at six weeks postpartum and found that the microbial load was low and similar to controls. The microbes identified were mostly consistent with skin and oral microbes, with some samples having no identifiable bacterial sequences. The results do not provide convincing evidence for the existence of a breastmilk microbiota at six weeks postpartum, suggesting that the microbes present in breastmilk may come from the infant's mouth and surrounding skin, as well as contamination during sampling and processing.

Summary: Multiple micronutrient (MMN) supplementation during pregnancy is common in high-income countries, and is associated with private obstetric care, private health insurance, and alignment with meat/vegetarian alternatives recommendations. There is a high reliance on supplements to meet the recommended intake of folate, iodine, and iron, which raises concerns about excessive nutrient intake. Effective strategies for optimizing nutrient intake during pregnancy, including promoting whole food diets and appropriate use of MMN supplements, need to be defined.
