Summary: This study investigates the effectiveness of the eHealth program Smarter Pregnancy on attitudes and practices towards fruit and vegetable intake and smoking in women attempting pregnancy through assisted reproductive technology (ART) or natural conception. The results show that the program can improve vegetable intake-related attitudes and practices in women undergoing ART treatment. However, there is no significant effect on fruit intake and smoking behavior.

Summary: This retrospective cohort study examined the relationship between periconception glycemic control and congenital anomalies in women with pregestational diabetes. Results showed that higher periconception HbA1c, especially above 9.5%, was significantly associated with major congenital fetal anomalies. The study sample was diverse, including women with type 2 diabetes and from various racial and ethnic backgrounds.

Summary: The study investigates the associations between bariatric surgery and determinants of periconception maternal health. Results show that after surgery, hormonal axes normalize, menstrual cycle regularity is restored, and fertility increases. There are generally no short-term risks for reproductive outcomes, although the risk of vitamin deficiencies is increased. Regular monitoring and personalized preconception care are recommended for women post-bariatric surgery.

Summary: Women's increased risk of HIV acquisition during pregnancy and postpartum may be due to changes in vaginal microbiota and/or cytokines. Concentrations of vaginal bacteria linked with HIV risk decreased during pregnancy and the postpartum period, while Lactobacillus spp and proinflammatory cytokines increased.

Summary: The study suggests that increased dietary intake of MUFAs during the periconception period may have a positive effect on achieving pregnancy, while increased intake of PUFAs does not show significant effects.

Summary: The study found that there is a high degree of continuity between binge drinking behaviors in adolescence and young adulthood and periconception alcohol use, indicating that women with a history of frequent or binge drinking are more likely to engage in risky drinking behaviors in early pregnancy.

Summary: This study investigated the relationship between reduction of asthma medication in the periconceptional period and asthma status and adverse pregnancy outcomes. Women who discontinued asthma medication prior to pregnancy had milder disease, fewer activity limitations, and fewer asthma attacks during pregnancy. However, there was a slight increase in the risk of adverse pregnancy outcomes for those who reduced medication.

Summary: Maternal red blood cell (RBC) folate levels before conception are associated with the risk of congenital heart disease (CHD) in offspring, suggesting that folic acid supplementation may be effective in CHD prevention. Further research is needed to confirm the preventive effect of periconception folic acid supplementation on CHD.

Summary: To ensure the safe navigation and real-time collision avoidance of unmanned surface vessels (USVs), this study conducts global and local path planning in a variable dynamic environment. The local path planning takes into account the USV motion characteristics and the requirements of COLREGs. The proposed local path planning algorithm is verified through simulation experiments with unknown obstacles, proving its effectiveness in ensuring collision avoidance decisions based on COLREGs when the USV encounters a ship.

Summary: This study investigated the association between pre-conception exposure to parabens and fecundity in couples of childbearing age. The findings showed that paraben exposure in female partners was associated with reduced couple fecundity, with AMH potentially mediating this relationship.

Summary: The study demonstrates that first-trimester utero-placental (vascular) development is associated with embryonic and fetal growth, with specific modifications based on fetal sex. This highlights the importance of monitoring first-trimester placental development and its impacts on embryonic and fetal growth.

Summary: There is growing evidence that optimal preconception health is associated with better reproductive, perinatal, and pediatric outcomes. Preconception care is recommended for all individuals planning pregnancy, providing an opportunity for medical providers and public health practitioners to improve health outcomes. Understanding the determinants of preconception health is important for all healthcare professionals and policymakers, and further research is needed to identify factors associated with positive health outcomes and ensure timely interventions. This article primarily focuses on clinical care, but recognizes the importance of population-health interventions considering larger social systems, structures, and policies in optimizing preconception health for individuals at risk of pregnancy.

Summary: This paper proposes an approach to optimize multi-path planning and solve barrier avoidance issues by combining the A* algorithm with the dynamic window method. Experimental results show that the enhanced A* algorithm performs better than the traditional A* algorithm in terms of path length and computation time.

Summary: This study found that prenatal exposure to high levels of SO2 may increase the risk of childhood asthma and wheezing. The first trimester may be a window for toxic effects, while the third trimester appears to be a sensitive time window for the effect of prenatal SO2 exposure on childhood asthma.
