Syncope in pregnancy, immediate pregnancy outcomes, and offspring long-term neurologic health.

Background: There are limited data regarding the perinatal consequences of maternal syncope during pregnancy, and even less is known about the potential long-term effect on offspring health.

Objective: This study aimed to examine perinatal outcomes as well as long-term offspring neurologic morbidity associated with prenatal maternal syncope, and the possible differential effect by trimester of first syncope episode.

Study Design: A retrospective cohort study was conducted, including all singleton deliveries occurring between 1991 and 2021 at a large tertiary medical center.

Maternal particulate matter exposure and gestational diabetes mellitus: a population-based cohort study.

Background: Gestational diabetes mellitus prevalence is steadily increasing worldwide, posing a significant threat to the short-term and long-term health of both mother and offspring. Because particulate matter air pollution has been reported to affect glucose metabolism, it was suggested that maternal particulate matter exposure may be associated with the development of gestational diabetes mellitus; however, the evidence is limited and inconsistent.

Objective: This study aimed to determine the association between maternal exposure to particulate matter of diameter ≤2.

Factors associated with COVID-19 vaccination likelihood during pregnancy.

Objective: To identify maternal background, medical and gynecological characteristics associated with COVID-19 vaccination likelihood, in the context where COVID-19 vaccination rates among pregnant women are significantly lower than the general population.

Methods: In a retrospective cohort study, including all women who delivered between January and September 2021, background and medical history, including current and previous pregnancies diagnoses, were compared between vaccinated and unvaccinated women. Multivariable logistic models were used to identify factors associated with vaccination for the entire population, and for the two distinctive populations included in the study (Bedouin Arabs and Jewish women).
