Pregnant women are often threatened by hypertension, symptoms of preterm labour, hepatopathy, and other. These complications might be the consequence of genetic factors together with involvement of environmental factors. We were searching for three polymorphisms Arg654Lys, Ala678Pro and Thr686Ala in exon 5, and two polymorphisms Phe802Leu, Ser827Ser/Leu in exon 7, and for the new mutations in exons 5 and 7 of the pregnancy-associated plasma protein A gene in the studied group consisting of 203 women - 79 pregnant women in time of preterm labour, 24 pregnant women suffering from preeclampsia, and 100 healthy pregnant and non-pregnant women serving as controls. We did not find any divergence from wild-type form of these polymorphisms in any of the studied groups, which led us to the hypothesis that these polymorphisms are not associated with our studied group of Caucasian origin. However, further studies with a larger group of subjects are needed to confirm our results.

To further evaluate the effects of lymphocyte immunotherapy (LIT) for the treatment of RPL patients this study aimed to utilize this type of treatment in RPL patients with positive antinuclear antibodies (ANA) in comparison to ANA-negative RPL women. To this aim, 84 ANA-positive, 114 ANA negative, and 50 healthy pregnant women were recruited. To examine the frequency of cells before and after LIT, flowcytometry technique was employed.

The identification of appropriate medication information sources requires adequate medical information literacy (MIL). It is important for pregnant women to comprehensively evaluate the risk of medication treatment, self-monitor their medication response, and actively participate in decision-making to reduce medication-related adverse events.

This study aimed to assess the severity of depressive symptoms and labor anxiety among Polish women in perinatal period during this crisis. From June 2, 2022, to April 11, 2023, 152 women completed three sets of online surveys-two during pregnancy (before 33 weeks and/or between 33 and 37 weeks) and one postpartum (4 weeks after childbirth).

Eight years after WHO adopted a resolution to eliminate hepatitis B by the year 2030, the disease remains a global public health concern, with vertical transmission of HBV being a major obstacle to this goal. Our study aimed to determine the HBV infection status of pregnant women in South Africa at a national level to evaluate the risk of vertical transmission and provide evidence for public health decision-making. We conducted HBsAg testing on 1,942 HIV-uninfected and 2,312 HIV-infected pregnant women from South Africa's public health sector in 2017, followed by HBeAg testing on HBsAg-positive samples.

Background: In 2017, the American College of Cardiology and American Heart Association (ACC/AHA) lowered blood pressure (BP) thresholds to define hypertension in adults outside pregnancy. If used in pregnancy, these lower thresholds may identify women at increased risk of adverse outcomes, which would be particularly useful to risk-stratify nulliparous women. In this secondary analysis of the SCOPE cohort, we asked whether, among standard-risk nulliparous women, the ACC/AHA BP categories could identify women at increased risk for adverse outcomes.
