Association between preconception body mass index and fertility in adult female: A systematic review and meta-analysis.

Obesity potentially reduces fertility, but systematic reviews are lacking to summarize the existing literature. Therefore, we systematically summarized the association between preconception body mass index (BMI) and fertility in adult female based on existing reports. Up to September 2023, we conducted literature retrievals in different databases, including Web of Science, PubMed, Wiley, and ScienceDirect.

Sex-Specific Associations between Maternal Thyroid Peroxidase Antibodies and Cognitive Development in Preschool Children: A Prospective Cohort Study.

An association between maternal thyroid dysfunction throughout pregnancy and the subsequent risk of neurodevelopmental abnormalities in offspring has been demonstrated. However, the potential effects of maternal thyroid autoimmunity on neurodevelopment in the absence of maternal hypothyroidism remain unclear. Therefore, in this study, we explored the association between maternal thyroid peroxidase antibody (TPOAb) positivity and cognitive development in preschool children.

Association Between Maternal Fasting Glucose Levels Throughout Pregnancy and Preschoolers' Refractive Errors.

Purpose: We aimed to investigate the association between maternal fasting plasma glucose (FPG) trajectories during pregnancy and children's refractive errors at 6 years of age.

Design: Based on the Ma'anshan Birth Cohort (MABC) in China, a total of 1987 mother-child pairs were included in this study.

Methods: Using the group-based trajectory model, trajectory fitting was performed on FPG levels during the first, second, and third trimesters of pregnancy.

Birth outcomes and early growth patterns associated with age at adiposity rebound: the Ma'anshan birth cohort (MABC) study.

Objective: Early onset of adiposity rebound (AR) is considered an early indicator of obesity risk. Our objective was to investigate the association of birth outcomes and early physical growth patterns with early AR in children.

Methods: Study subjects (n = 2705) were enrolled from the Ma'anshan birth cohort (MABC).

Placental inflammatory cytokines mRNA expression and preschool children's cognitive performance: a birth cohort study in China.

Background: The immunologic milieu at the maternal-fetal interface has profound effects on propelling the development of the fetal brain. However, accessible epidemiological studies concerning the association between placental inflammatory cytokines and the intellectual development of offspring in humans are limited. Therefore, we explored the possible link between mRNA expression of inflammatory cytokines in placenta and preschoolers' cognitive performance.

Early sleep duration trajectories and children's cognitive development: a prospective cohort study.

Unlabelled: We aimed to investigate the association between sleep duration trajectories and cognitive performance in preschool-aged Chinese children. We included 2131 children from the Ma'anshan birth cohort (MABC) study. Sleep duration trajectories from 6 to 48 months of age were determined using the group-based trajectory modeling (GBTM).

Maternal anxiety during pregnancy and children's asthma in preschool age: The Ma'anshan birth cohort study.

Background: The fetal immune system and consequent elevated risk of asthma in childhood may be impacted by maternal anxiety during pregnancy. Limited studies have evaluated whether there was a sensitive period and cumulative effect of the relationship between prenatal anxiety and children's asthma.

Methods: 3131 mother-child pairs made up the study's sample from the Ma'anshan Birth Cohort Study in China.

Maternal pregnancy-related anxiety and children's physical growth: the Ma'anshan birth cohort study.

Background: Epidemiological studies have identified maternal antenatal anxiety and several adverse birth outcomes, but limited studies have focused on the relationship with the long-term physical growth of children. The study aimed to assess the influence of maternal pregnancy-related anxiety on physical growth in children at different exposure periods during pregnancy.

Methods: 3,154 mother-child pairs were included based on the Ma'anshan birth cohort study.

Peri-Conceptional Folic Acid Supplementation and Children's Physical Development: A Birth Cohort Study.

Background: Maternal lack of folic acid supplementation during pregnancy may increase the risk of low birth weight and preterm delivery. However, little is known about the relationship between folic acid supplementation during pregnancy and the physical development of offspring in the later stage.

Objective: This study aimed to explore the association between maternal folic acid supplementation status during pregnancy and the physical development of preschool children.

Impact of pregnancy-related anxiety on preschoolers' emotional and behavioral development: Gender specificity, critical time windows and cumulative effect.

Background: Studies on the gender-specific effect of PrA on children's emotional and behavioral development are limited. Lack of PrA data on the entire pregnancy had caused difficulties in identifying the key time window and cumulative effects.

Modeling of Polycrystalline Material Microstructure with 3D Grain Boundary Based on Laguerre-Voronoi Tessellation.

Voronoi tessellations are shown to be statistically representative of polycrystalline microstructures, which have been widely accepted for the modeling of microstructures of metallurgic and ceramic materials. In this paper, a new implementation of the Voronoi diagram in Laguerre geometry is presented for the generation of numerical models of polycrystalline microstructures, where the size and shape of the grains can be controlled, and the 3D grain boundaries can be modeled with a specified thickness. The distribution of grain sizes in the models is fitted to a lognormal distribution, compared with the normal distribution in the Voronoi tessellation methods.
