Preeclampsia is a disorder occurring during pregnancy typically after 20 weeks of gestation. It affects both mother and unborn baby in at least 5-8% of all pregnancies. It is a rapidly progressive condition characterized by high blood pressure and the presence of protein in the urine. The symptoms, such as swelling, sudden weight gain, headaches and vision disturbances, are important signs of preeclampsia which can lead to maternal and infant illness and death. It is estimated that this disorder is responsible for 76,000 maternal and 500,000 infant deaths each year. The main hypothesis explaining the development of preeclampsia is the theory of placental hypoxia/ischemia. An imbalance between vascular endothelial growth factor (VEGF) and soluble fms-like tyro-sine kinase-1 (sFlt-1) seems to play a crucial role. Currently there is no way to predict, with certainty whether preeclampsia will develop during a given pregnancy. There is a need for a diagnostic tool which can help to identify and monitor women at risk. There is growing evidence that podocyturia - urinary excretion of viable podocytes may be a useful predictor of preeclampsia. This paper presents facts supporting such a hypothesis.

Is there a risk of developmental problems in infants born to mothers with gestational diabetes mellitus and/or pre-eclampsia?

Objective: The aims of this study were (i) to describe the early spontaneous movements in 3-to 5-month-old infants in groups of infants born to mothers with GDM and/or PE, (ii) to compare them, and (iii) to analyze the differences between infants with these risk factors and typically developing infants born to mothers without GDM and/or PE and other risk factors.
Methods: This cohort study included 255 infants in 4 groups: (i) 96 infants born to mothers with GDM, (ii) 78 infants born to mothers with PE, (iii) 31 infants born to mothers with GDM and PE, and (iv) 50 typically developing infants. Early spontaneous movements, including not only fidgety movements but also concurrent movement and postural patterns, were assessed using the General Movements Assessment (GMA), which determines the Motor Optimality Score-Revised (MOS-R).

Immunization rates of maternal influenza vaccination during pregnancy remain suboptimal, with concerns about potential harm to the mothers and their offspring. We conducted a population-based cohort study, using mother-child linked database in Korea: (a) maternal cohort between December 2019, and March 2022; (b) neonatal cohort between September 2020, and June 2021. Exposure was defined as influenza vaccination during pregnancy.

Preeclampsia (PE) is a pregnancy-specific disorder characterized by an unclearly understood pathogenesis and poses a great threat to maternal and fetal safety. Cuproptosis, a novel form of cellular death, has been implicated in the advancement of various diseases. However, the role of cuproptosis and immune-related genes in PE is unclear.

Wernicke's Encephalopathy (WE) is a rare but severe condition primarily caused by thiamine deficiency, often seen in pregnant women who experience severe vomiting, such as in hyperemesis gravidarum. This case report details a 38-year-old woman at 27 weeks of gestation who developed altered consciousness, cerebellar ataxia, and hyperlactatemia following persistent vomiting. Brain MRI demonstrated characteristic bilateral abnormalities consistent with WE.

Objective: To investigate the association between functional parameters of the microcirculation and the systemic cardiovascular system in a population of pregnant women at risk for gestational hypertension disorders.
Study Design: For this observational study, women at high cardiovascular risk according to maternal anthropometrics, obstetric and medical history, were recruited at random gestational age depending on time of referral to the outpatient clinic for high risk prenatal care at Ziekenhuis Oost Limburg, Genk Belgium. After birth, data of maternal and neonatal outcome were obtained from the hospital records: only women with normal pregnancy (n = 142) and with preeclampsia (n = 34) were included in this analysis.
