Introduction: Pregnancy related anxiety (PrA) is a unique type of anxiety during pregnancy. PrA can affect both maternal and infant health, as well as pregnancy outcomes. The purpose of this study was to culturally translate the Pregnancy-Related Anxiety Questionnaire-Revised 2 (PRAQ-R2) into Chinese and evaluate its psychometric properties in Chinese women during pregnancy irrespective of parity.

Methods: There were 411 Chinese pregnant women recruited from September 2020 to June 2021. The Cronbach's alpha, split-half reliability, and test-retest reliability were used to evaluate the reliability of PRAQ-R2 Chinese version. Validity was analyzed through content validity, convergent validity, discriminant validity and construct validity.

Results: The Chinese version of PRAQ-R2 showed good reliability and validity. The Cronbach's alpha coefficients of the total scale and subscales were all greater than 0.7. The median score (interquartile range, IQR) of PRAQ-R2 was 27 (32, 22). The correlation coefficient between item and hypothesis subscale were all greater than 0.40, indicating good convergence validity. Our findings revealed three dimensions of this scale by exploratory factor analysis and confirmed the original version of PRAQ-R2: worries about bearing a handicapped child, concern about own appearance, and fear of giving birth, with a total variance of 72.84% explained. The confirmatory factor analysis showed accepted model fit indexes.

Limitations: All pregnant women were recruited from one region in China, and the study lacked the longitudinal design. Future longitudinal multi-central studies are needed.

Conclusion: The Chinese version of PRAQ-R2 can be used as a promising tool to measure PrA in Chinese pregnant women without comorbidities and complications.

Chemotherapeutic agents such as methotrexate (MTX), raltitrexed (RTX), 5-fluorouracil (5-FU), hydroxyurea (HU), and retinoic acid (RA), and valproic acid (VPA), an antiepileptic drug, all can cause malformations in the developing central nervous system (CNS), such as neural tube defects (NTDs). However, the common pathogenic mechanisms remain unclear. This study aimed to explore the mechanisms of NTDs caused by MTX, RTX, 5-FU, HU, RA, and VPA (MRFHRV), based on network pharmacology and molecular biology experiments. Read More

Background: Early and intermediate serological screening cannot detect sex chromosome abnormalities. Currently, noninvasive prenatal testing (NIPT) is the only procedure available for screening such disorders; however, its use is controversial.

Methods And Results: A total of 47,855 pregnant women underwent NIPT at our referral center from January 2014 to December 2020. Read More

Human cytomegalovirus (HCMV) shedding has been extensively investigated in newborns and in young children, however, much less is known about it in immunocompetent adults. Shedding of HCMV was investigated in saliva, vaginal secretions and urine of pregnant women experiencing primary infection along with the development of the HCMV-specific immune response. Thirty-three pregnant women shed HCMV DNA in peripheral biological fluids at least until one year after onset of infection, while in blood HCMV DNA was cleared earlier. Read More
