AI Article Synopsis

  • The study aimed to assess the risk of major congenital malformations linked to the use of second-generation antipsychotics (SGAs) in pregnant women during the first trimester.
  • A total of 404 women participated, with outcomes showing that the rate of major congenital malformations was 0.9% in the SGA group compared to 1.8% in the comparison group of non-exposed women.
  • The results indicated no significant association between SGA exposure and an increased risk of major congenital malformations, suggesting these findings may provide reassurance for pregnant women needing SGAs.

Article Abstract

To investigate the risk of major congenital malformations associated with exposure to second-generation antipsychotics (SGAs) in the first trimester. Pregnant women who received consultation on drug exposure from the Japan Drug Information Institute in Pregnancy from October 2005 to December 2016 were asked to complete a questionnaire at 1 month after the expected delivery date. The questionnaire included items on pregnancy outcome, date of delivery, gestational age at delivery, malformations in the infant that were confirmed by the pediatrician's report, and the following parameters at birth: height, weight, head circumference, and chest circumference. Odds ratios (ORs) for major congenital malformations among live-born children of pregnant women with SGA exposure during the first trimester (SGA group) relative to children of women not exposed to SGAs and medications known to be teratogenic (comparison group) were estimated using an inverse probability of treatment weighting approach. Of 404 women with SGA exposure during the first trimester, there were 351 live births, 3 stillbirths, 34 spontaneous abortions, and 16 elective abortions. The rate of major congenital malformations among live-born children was 0.9% (3/351) in the SGA group and 1.8% (70/3,899) in the comparison group. No statistically significant differences were observed in the adjusted OR for major congenital malformations (adjusted OR = 0.44; 95% CI, 0.12-1.48;  = .179). SGA exposure during the first trimester is not associated with an increased risk of major congenital malformations. These findings might be reassuring for pregnant women who require SGAs.

Background: Congenital anomalies (CAs) encompass a wide spectrum of structural and functional abnormalities during fetal development, commonly presenting at birth. Identifying the cause of CA is essential for accurate diagnosis and treatment. Using a target-gene approach, genetic variants could be found in certain CA patients.

Objective: Size at birth is a key indicator of in utero growth. Our objective was to generate sex-specific percentiles for birth weight and head circumference in neonates born between 22 and 29 weeks gestation from pregnancies without hypertension or diabetes and assess differences between vaginal and caesarean births and between singletons and twins.

Methods: We used data from 12 countries participating in the International Network for Evaluating Outcomes in Neonates database from 2007 to 2021.

Introduction: Screening for congenital adrenal hyperplasia through the measurement of 17-hydroxyprogesterone on the neonatal blood spot aims to: a) prevent neonatal deaths; b) allow earlier identification and thereby decrease the severity of the initial salt-wasting episode; and c) shorten the time during which a severely virilized genetic female newborn may be assigned the male sex. It is now practiced in the majority of high-income countries, although the positive predictive value of the test is very low in infants born preterm, who seem to be infrequently affected. In almost all low- and middle-income countries, it has not yet been implemented.

Anomalous aortic origin of a coronary artery (AAOCA) is a rare congenital anomaly with a large spectrum of anatomical variations. Selective engagement of an AAOCA can present challenges during cardiac catheterization. A comprehensive understanding of the characteristics of major AAOCA can effectively assist operators for selecting and maneuvering catheters.

Neonates with congenital heart disease (CHD) who undergo cardiopulmonary bypass (CPB) are at high-risk for unfavorable neurodevelopmental (ND) outcomes and are recommended for ND evaluation (NDE); however, poor rates have been reported. We aimed to identify risk factors associated with lack of NDE. This single-center retrospective observational study included neonates < 30 days old who underwent CPB and survived to discharge between 2012 and 2018.
