To establish the reference values for PAPP-A and total hCG between 11 and 13 weeks of gestation for the use of risk assessment of fetal aneuploidy in Japanese pregnant women. A multicenter prospective study was conducted. The subjects included only Japanese pregnant women with viable singleton who requested the first trimester combined (nuchal translucency and maternal serum marker) screening for fetal aneuploidy. Reference values of PAPP-A and total hCG in Japanese population were made and compared with them in Caucasian. Overall 1,751 Japanese pregnant women were analyzed. Median vales of maternal serum concentration in Japanese pregnant women from 11 + 0-13 + 6 weeks' gestation were ranged from 3.01 to 9.51 mIU/mL for PAPP-A and from 70.2 to 58.3 IU/mL for total-hCG, respectively. Regression curve of median maternal serum PAPP-A and total-hCG concentration against gestational days are significantly higher in Japanese comparing with Caucasian. At most distant values, Japanese serum concentration indicated 1.45 MoM for total-hCG and 1.70 MoM for PAPP-A based on Caucasian regression curves. A modification of the equations by specific reference values is necessary for Japanese pregnant women at the risk assessment of chromosomal abnormalities using the first trimester maternal serum marker.

Objective: To explore the genetic characteristics of a Chinese pedigree with rare mosaic 11q partial duplication and its pathogenetic mechanisms.
Methods: A pedigree which underwent prenatal diagnosis at Wenzhou Central Hospital between September 25, 2015 and November 30, 2023 was selected for the study. Clinical data were collected from the pedigree.

Children's eating habits are established early in life and parents play a major role therein. Pregnancy is a teachable moment for the promotion of healthy eating because many women are concerned about their babies' health and have frequent contact with healthcare providers. We aimed to investigate the association between diet quality during pregnancy and the offspring.

Article Synopsis
- Group B streptococcus (GBS) is a significant cause of infections in neonates and pregnant women, with Japan implementing guidelines for screening and antibiotic use, yet infections have not decreased significantly.
- Approximately 15% of pregnant women lack GBS screening, and issues like intermittent colonization lead to early-onset disease; current preventative measures don't address increasing cases of late-onset disease.
- This study found that using polymerase chain reaction for GBS detection was more effective than culture methods, highlighted the risk of horizontal transmission, and emphasized the need for better diagnostic tools and potential maternal vaccination for prevention.

The use of Japanese herbal medicines (Kampo medicines), rooted in centuries of traditional practice, lacks extensive Western scientific validation regarding their safety. Concerns include potential risks such as placental dysplasia, miscarriage, teratogenicity, and fetotoxicity when administered to pregnant women. Therefore, scientific safety evaluations are crucial for the appropriate use of Kampo medicines during pregnancy.

Introduction: Information disclosure is important in promoting unsafe food recalls and reducing potential food safety risks. However, the governance of unsafe food recall information in China is distorted, leading to cognitive dissonance in Chinese consumers' perceptions of unsafe food recall information. Focusing on consumers' search and cognitive costs, this study suggests that market regulators should proactively and fully disclose unsafe food recall information to satisfy consumers' needs and preferences for recall information, thereby optimizing consumer perceptions and facilitating the improvement of the information governance system for unsafe food recalls.
