Summary: This study investigates the changes in salivary oxytocin levels and psychological state of women with emergency cesarean section, and explores the relationship between oxytocin level changes and postpartum blues. The results show a significant decrease in oxytocin levels at 5 days postpartum, which is correlated with postpartum blues. However, due to the small sample size, the association could not be analyzed and further research with larger sample sizes is needed to clarify this relationship.

Summary: The rate of cesarean delivery on maternal request has been increasing in the United States over the last few decades. This study aims to describe the prevalence and trends of this type of cesarean delivery and compare the characteristics and outcomes of women who opt for it. The study found that cesarean delivery on maternal request is more common among older women with higher income and private insurance. However, it is associated with higher risks of adverse events, such as thromboembolism and myocardial infarction.

Summary: This study aims to evaluate the effects of extending the second stage of labor in women attempting a trial of labor after a cesarean section (TOLAC). A retrospective cohort study comparing two periods found that extending the second stage to 3 hours significantly decreased repeat cesarean delivery rate, but also increased instrumental delivery rates, uterine rupture, fetal acidemia, and neonatal intensive care unit admissions. These findings suggest the need for further consideration of allowing a prolonged second stage in TOLAC patients.

Summary: Children delivered by elective C-section are not exposed to the birth canal and have altered microbiota development, which can affect their metabolic and immune programming and increase the risk of immune and metabolic diseases. Vaginal seeding can increase the transmission of maternal microbiota to neonates and cause changes in the composition and diversity of their skin and stool microbiota.

Summary: This study evaluated the association between timing and indication for previous cesarean section (C-section) and its impact on postpartum risks for adverse maternal outcomes, especially postpartum hemorrhage (PPH) in vaginal birth after cesarean (VBAC). The results showed that VBAC is linked to higher rates of postpartum complications, primarily PPH, with significantly increased risk following a second-stage cesarean section. This data should be considered in the management of laboring women after C-section.

Summary: With the increasing health risk of high temperature due to climate change, it is important to quantify the scale of the problem. However, estimating the burden of disease (BoD) attributable to high temperature can be challenging due to geographical variations in risk patterns and data accessibility issues. This study presents a methodological framework that refines exposure levels using Koppen-Geiger climate zones and estimates the difference between observed burden and theoretical minimum risk exposure distribution (TMRED). It can be used to estimate burdens across climate zones and enhance the reproducibility and transparency of BoD research.

Summary: The aim of this study was to establish the daily risk estimates of the relationships between grass, tree, and weed pollen and asthma health outcomes. The findings showed that there were differences between children and adults in the timing of health effects. Children's asthma outcomes were positively related to grass pollen in May and to weed pollen from February to May. For adults, the health outcomes related to weed pollen were limited to February. Adults were not affected by tree pollen, while children's asthma morbidity was associated with tree pollen in August and September. These results indicate the importance of year-round pollen monitoring and health campaigns to prevent asthma in the community.

Summary: The study shows that over the past 51 years, global warming has led to an increase in the ratio of summer to winter mortality in Australia, with a faster increase in years with above-average temperatures. As a result, it is concluded that as temperatures rise, mortality in the hottest and coldest months of the year will gradually converge.
