To evaluate whether the presence of proteinuria, although no longer mandatory in the revised diagnostic criteria, results in worse maternal and fetal outcomes in preeclampsia (PE). A retrospective cohort study was conducted, analyzing data from pregnant patients diagnosed with PE between January 2015 and December 2019 at a tertiary care center in Brazil. Ethical approval was obtained, and the patient records were reviewed to assess maternal and perinatal outcomes based on the revised diagnostic criteria by the College of Obstetricians and Gynecologists, focusing on the presence or absence of proteinuria.

Preeclampsia (PE) is a hypertensive pregnancy syndrome associated with target organ damage and increased cardiovascular risks, necessitating antihypertensive therapy. However, approximately 40% of patients are nonresponsive to treatment, which results in worse clinical outcomes. This study aimed to compare circulating proteomic profiles and identify differentially expressed proteins among 10 responsive (R-PE), 10 nonresponsive (NR-PE) patients, and 10 healthy pregnant controls (HP).

Hypertensive diseases of pregnancy (HDPs) represent a global clinical challenge, affecting 5-10% of women and leading to complications for both maternal well-being and fetal development. At the heart of these complications is endothelial dysfunction, with oxidative stress emerging as a pivotal causative factor. The reduction in nitric oxide (NO) bioavailability is a vital indicator of this dysfunction, culminating in blood pressure dysregulation.

Article Synopsis
  • - This study assessed the effectiveness of fetal Doppler ultrasound and various maternal factors in predicting cesarean sections caused by intrapartum fetal compromise (IFC), low Apgar scores, and adverse perinatal outcomes in high-risk pregnant women.
  • - Conducted on 613 women, it found that specific measurements like abnormal umbilical artery resistance index (UA RI) and cerebroplacental ratio (CPR) were key indicators for cesarean sections and low Apgar scores, whereas maternal traits did not significantly influence outcomes.
  • - The research concluded that high UA RI is a strong predictor for adverse perinatal outcomes, and that CPR can effectively signal potential cesarean sections due to IFC in late preterm and

Objective: Little is known about the effect of maternal immunological factors on the etiology of developmental defects of enamel (DDE). RANTES (Regulated on Activation Normal T Cell Expressed and Secreted) is a chemokine produced by fibroblasts, lymphoid and epithelial mucosa cells in response to various external stimuli. Despite its importance for embryogenesis, RANTES expression has been demonstrated in multiple diseases characterized by inflammation, tumor and immune response, and wound healing.

Objective:  It is a challenge to consider preeclampsia (PE) diagnosis and management in low and middle-income settings, where it represents a major public health concern. The placenta is the underlying cause of disease, and the plasma concentrations of proangiogenic and antiangiogenic factors released by the placenta can reflect the risks of disease progression. Antiangiogenic proteins, such as soluble fms-like tyrosine kinase 1 (sFlt-1), and proangiogenic, like placental growth factors (PlGF), are directly and inversely correlated with the disease onset, respectively.

Background And Aims: Preeclampsia (PE) is a gestational hypertensive disease responsible for high maternal and fetal morbidity and mortality. The increase in blood pressure is associated with a decrease in the bioavailability of nitric oxide (NO). Arginase interferes with NO production consuming L-arginine, a substrate required by endothelial NO synthase to NO formation.

Preeclampsia (PE) is a hypertensive disorder of pregnancy and it is one of the main causes of maternal and fetal morbidity and mortality worldwide. It is known that oxidative stress plays a role in its pathophysiology, therefore we investigated the effects of trans-resveratrol, a potent antioxidant, on the Nrf2/ARE pathway, nitric oxide (NO) production, and reactive oxygen species (ROS) levels in an in vitro model of PE. Plasma from PE patients increased ARE activity in endothelial cells compared with plasma from healthy pregnant (HP), and the addition of resveratrol was able to potentiate this increase only in PE.

Pre-eclampsia (PE) is a severe disorder that affects up to 8% of all pregnancies and represents an important cause of maternal and perinatal morbidity and mortality. The screening of the disease is a subject of studies, but the complexity and uncertainties regarding its etiology make this objective a difficult task. In addition, the costs related to screening protocols, the heterogeneity of the most affected populations and the lack of highly effective prevention methods reduce the potential of current available algorithms for screening.

Article Synopsis
  • Some studies show that how a baby is born (vaginally or by cesarean) can affect pelvic floor muscle (PFM) strength differently, but the results are mixed.
  • This study looked at whether there was a difference in PFM function right after giving birth between first-time moms who had cesarean births and those who had vaginal births.
  • After reviewing many studies, the researchers found that there was no significant difference in PFM strength between moms who had cesarean sections and those who had vaginal deliveries right after childbirth.
