Fetal Diaphragmatic Excursion Is Decreased in Hospitalized Pregnant Women Infected with COVID-19 during the Second and Third Trimesters.

Objective: In the present study, we aimed to evaluate coronavirus disease 2019 (COVID-19) infection effects on fetal diaphragm thickness and diaphragmatic excursion, which together show the quality of diaphragmatic contractions.

Study Design: One hundred and ninety-two pregnant women were included in this prospective case-control study. Patients were divided into four groups according to their COVID-19 infection history in their second or third trimester: hospitalized COVID-19-infected pregnant women group ( = 48), outpatient COVID-19-infected pregnant women group ( = 48), common cold (COVID-19 polymerase chain reaction negative) pregnant women group ( = 48), and noninfected healthy controls ( = 48).

Severe Intrahepatic Cholestasis Pregnancy Is Associated With Maternal Endothelial Dysfunction: A Case-Control Study.

Objective: The aim of the present study was to evaluate maternal serum endocan levels, which are markers of vascular pathologies and strongly associated with vascular inflammation and endothelial dysfunction, in pregnancies complicated by intrahepatic cholestasis of pregnancy (ICP).

Methods: The study comprised 30 pregnant women with mild ICP, 30 pregnant women with severe ICP, and 30 healthy pregnant women as a control group. The inclusion criteria were women with ICP, which was diagnosed based upon the presence of pruritus associated with elevated total bile acid (TBA) levels (> 10 μm/L), elevated aminotransferases, or both, and the absence of diseases that may produce similar laboratory findings and symptoms.

The effect of steroid administration on fetal diaphragm function.

Background: Antenatal steroid administrations lead to not only accelerated lung maturation, improved blood gas measurements but also lung dynamics and lung compliance. This study aimed to investigate structural and functional changes in diaphragm after antenatal steroid administration.

Methods: The 79 volunteers were divided into 2 groups according to presence of preterm delivery.

Evaluation of maternal serum progesterone-induced blocking factor levels in pregnancies complicated with early- and late-onset preeclampsia.

The aim of present study was to evaluate maternal serum progesterone-induced blocking factor (PIBF) levels in pregnancies complicated with early-onset (EO-PE) and late-onset (LO-PE) preeclampsia. Patients with preeclampsia were divided in two groups according to preeclampsia onset and compared to healthy control group: EO-PE and LO-PE defined as being diagnosed before 340/7 and ≥340/7 weeks, respectively. Maternal age, nulliparity, BMI at blood sampling, smoking, history of caesarean section and ethnicity were statistically similar among the groups.
