Phthalates are common endocrine disruptors. The placental barrier can be crossed by phthalates and may have a negative impact on the health of the fetus. However, the association between prenatal exposure to phthalates and birth size is still debatable. Here, we performed this meta-analysis to assess the relationship between prenatal phthalates exposure and birth size. Eighteen studies were finally included by searching PubMed, Embase, Scopus, Ovid, and Web of Science databases and standardized regression coefficients and standard errors were used to pool effect size. Our results showed that prenatal exposure to MMP (=-0.04, 95%CI: -0.08, -0.01) and MEP (=-0.01, 95%CI: -0.01, -0.002) was significantly associated with birth weight. However, no significant associations were identified for phthalate exposure with birth length, head circumference and chest circumference. Because the limiting of studies, more high-quality case-control studies or cohort studies are urgently needed to draw the best conclusions.

Background: Animal studies show ovarian follicle damage and mutagenesis after ionizing radiation exposure. Computed tomography (CT) imaging is commonly done outside pregnancy, but risks to future pregnancy are unknown.
Objective: To evaluate the risk for spontaneous pregnancy loss and congenital anomalies in offspring of women exposed to CT ionizing radiation before conception.

Importance: Neonatal intensive care has advanced over recent decades, yet premature birth remains associated with increased neonatal mortality and morbidity.
Objective: To describe health service use, morbidity, and medication needs up to age 5 years in a contemporary cohort of children born preterm.
Design, Setting, And Participants: This population-based cohort study was conducted in British Columbia (BC), Canada, using health service and pharmacy data linked using provincial administrative databases.

Importance: For the first time in nearly 2 decades, the US infant mortality rate has increased, coinciding with a rise in overdose-related deaths as a leading cause of pregnancy-associated mortality in some states. Prematurity and low birth weight-often linked to opioid use in pregnancy-are major contributors.
Objective: To assess the health and economic impact of perinatal opioid use disorder (OUD) treatment on maternal and postpartum health, infant health in the first year of life, and infant long-term health.

Importance: Trisomy 13 (T13) and trisomy 18 (T18) are chromosomal abnormalities with high mortality rates in the first year of life. Understanding differences in long-term survival between children with full vs mosaic or partial trisomy is crucial for prognosis and health care planning.
Objective: To examine the differences in 10-year survival between children with full T13 and T18 vs those with mosaic or partial trisomy.

There is a growing body of evidence that the interaction between various microbial organisms and the human host can affect various physical and even mental health conditions. Bidirectional communication occurs between the brain and the gut microbiome, referred to as the brain-gut-microbiome axis. During aging, changes occur to the gut microbiome due to various events and factors such as the mode of delivery at birth, exposure to medications (e.
