Summary: This study used methods from the chemical machine learning field to identify lesions associated with stillbirths at different gestational ages (GAs) based on correlation. The findings revealed four specific lesions that distinguish GA ranges among all stillbirths.

Summary: Maternal fructosamine levels at the time of delivery were found to be significantly higher in women with stillbirth compared to women with live birth. The differences were more pronounced in women with diabetes, indicating a potential benefit of glycemic control during pregnancy for these women.

Summary: This study investigates the strategic interactions between passengers, airlines, and airports, and proposes a dual-layer game-theoretic model to optimize subsidy strategies for promoting collaborative development among multiple airports. The results reveal that the optimal fare discount intervals are contingent upon travel distances and passenger rationality, and targeted airport subsidy strategies can enhance inter-airport route coordination.

Summary: The study found that many parents globally experience disrespectful care around stillbirth, highlighting the need for provider training and system-level support to address these issues. Some aspects of care quality need improvement, such as ensuring families have enough time with providers.

Summary: Women's social networks play a crucial role in providing support to mothers who have experienced a stillbirth, especially in terms of emotional and information support. Characteristics such as trust, frequency of contact, and reliance on specific individuals within the network are predictors of eventual social support. Intervention strategies at the community level should utilize these network characteristics to benefit mothers experiencing stillbirth.

Summary: This study examined the association between fetal/placental DNA copy number variants (CNVs) and pathologic placental lesions (PPLs) in pregnancies complicated by stillbirth. The findings showed that abnormal placental/fetal CNVs were associated with maternal vascular PPLs in stillbirth cases. This insight into specific genetic abnormalities associated with placental dysfunction and stillbirth may provide valuable information for further research.

Summary: This study investigated the association of placental and fetal DNA copy number variants (CNVs) with fetal structural malformations (FSMs) in stillborn fetuses. Specific CNVs were found to be associated with FSMs, which has important implications for counseling and care for pregnant women at risk of stillbirth.

Summary: The study aimed to assess the risks for maternal and neonatal outcomes associated with elective delivery at different gestational ages ranging from 37 0/7 to 39 6/7 weeks among women with at least 2 previous cesarean deliveries. The results showed that elective delivery at 39 weeks was associated with decreased risk for adverse outcomes compared to expectant management.

Summary: The mode of delivery for stillbirths in a region of Italy is not determined by the gestational age at the time of fetal death, but rather by the presence of placenta disorders. These findings can assist obstetric providers in managing stillbirth deliveries.

Summary: This research introduces the single truck multi-drone routing and scheduling problem for last-mile parcel delivery. A mixed integer linear programming (MILP) model is developed to minimize the delivery completion time, and a variant is introduced to minimize the total delivery cost. The proposed relax-and-fix with re-couple-refine-and-optimize (RF-RRO) heuristic approach and deep learning-based clustering procedure show promising results in solving the problem and improving delivery efficiency.

Summary: Stillbirth is a devastating pregnancy outcome, and a screening tool for identifying at-risk fetuses is still elusive. Maternal reporting of decreased fetal movements (DFM) is associated with adverse perinatal outcomes, but not significantly with stillbirth. The presence of DFM is a marker for increased risk in a fetus, and may lead to other adverse outcomes such as being born small for gestational age.

Summary: This study examines the relationship between placental lesions and cause of death in stillbirths of different gestational ages. The findings highlight the importance of specific placental lesions in distinguishing stillbirths at different gestational ages and understanding the underlying causes of death.

Summary: This study evaluated the clinical outcomes in children with prenatally diagnosed congenital lung malformations and found that an initial CVR <= 1.4 identifies fetuses at very low risk for hydrops, and a maximum CVR < 0.9 is associated with asymptomatic disease at birth.

Summary: The incidence of stillbirth has declined in the Stockholm Region, but among women originating from sub-Saharan Africa, the incidence has significantly increased, with a higher likelihood of premature stillbirth and multiparity.
