Introduction When COVID-19 vaccination started, there was little data on the safety of immunization against COVID-19 infection in pregnant women. Previous studies revealed no safety concerns for pregnant women or newborns who received a messenger ribonucleic acid (mRNA) COVID-19 vaccine during pregnancy. This study aimed to investigate the effects of COVID-19 vaccination on pregnant women and on perinatal outcomes. Methods This cross-sectional study was conducted in a maternity hospital in King Saud Medical City. It started in January 2022 and ended in June 2022. The questionnaire was developed and validated by experts. This study included all women admitted to the postpartum ward who were more than 18 years old and had received the COVID-19 vaccine. The study excluded women who had no proof of their vaccination status or who could not complete the questionnaire. The primary outcome was the effect of COVID-19 vaccination on gestational age and birth weight. The secondary outcomes included the development of polyhydramnios, oligohydramnios, mode of delivery, Apgar score, postpartum hemorrhage, and neonatal intensive care unit admission. Results A total of 365 pregnant women participated in this study. The mean gestational age of the unvaccinated women was 38.83 ± 1.62 weeks, which was significantly (p < 0.001) higher than that of vaccinated women (37.69 ± 2.9 weeks). In addition, the average birth weight for the unvaccinated women was 2.96 ± 0.4 kg, which did not differ significantly (p = 0.89) from that of vaccinated women (2.97 ± 0.66 kg). Conclusion COVID-19 vaccination, regardless of the type of vaccine received before, during, or after pregnancy, is not associated with any unfavorable perinatal outcomes for pregnant women or neonates.

Ratio of remnant cholesterol to high-density lipoprotein cholesterol in relation to gestational diabetes mellitus risk in early pregnancy among Korean women.
PLoS One

Department of Clinical Laboratory, Suzhou Ninth People's Hospital Affiliated to Soochow University, Suzhou, Jiangsu, China.
Objective: There is no evidence to suggest that an association exists between the remnant cholesterol (RC) to high-density lipoprotein cholesterol (HDL-C) ratio and gestational diabetes mellitus (GDM). In this study, the RC/HDL-C ratio during the first trimester was examined as a potential indicator of the onset of GDM during the second trimester.
Methods: This was a secondary analysis of data from a Korea-based prospective cohort study.

Background: Endoplasmic reticulum stress with protein misfolding has been introduced as a key pathogenetic mechanism in lupus nephritis (LN). Pregnancy is thought to exaggerate proteostasis, which leads to the accumulation of potentially pathogenic misfolded proteins in the urine, serum, and placenta particularly in women with preeclampsia. The detection of misfolded proteins is made using Congo red stain, which is referred to as congophilia.

Objective: This study sought to estimate population level prevalence of infertility and explored whether time to pregnancy is related to selected factors.
Methods: This study's analysis was based on data collected from 2081 women who were sampled from participants of the 2016 Ethiopia Demographic and Health Survey based on risk of pregnancy criteria: age between 15 and 49 years, currently married or cohabitating, sexually active, not used contraception method during the 5 years before interview, not menopausal, and not pregnant. We used a current duration (CD) approach in which for each woman we calculated the length of time-at-risk of pregnancy (CD value) in months.

Background: Genetic screening has advanced from prenatal cell-free DNA (cfDNA) screening for aneuploidies (cfDNA-ANP) to single-gene disorders (cfDNA-SGD). Clinical validation studies have been promising in pregnancies with anomalies but are limited in the general population.
Methods: Chart review and laboratory data identified pregnancies with cfDNA-SGD screening for 25 autosomal dominant conditions at our academic center.

This study determines video's effect on pregnant women's pain, anxiety, and perception of labor using virtual reality glasses during the active and transition phases of childbirth. This randomized controlled study was conducted with 60 pregnant women (30 in each group) admitted to the delivery room of a hospital. The data were collected by personal information form, visual comparison scale-pain, visual comparison scale-anxiety, and perception of birth scale.
