Placenta location, a prognostic determinant for the incidence of preeclampsia.

Background: Preeclampsia is one of the complications of pregnancy with uncertain etiology. Nevertheless, it is believed that the condition may arise due to abnormal trophoblastic invasion, resulting in vascular remodeling and increased resistance in the spiral arteries. It is assumed that the location of the placenta might have contributed to the formation of trophoblastic invasion and further placental supply.

Anesthetic anaphylactic shock in an emergency cesarean section: a case report.

Background: Neuraxial anesthesia is the gold standard for cesarean sections, but general anesthesia is sometimes necessary, especially in emergency cases. Anaphylactic shock due to succinylcholine, a commonly used neuromuscular blocking agent, is rare but life-threatening.

Case Presentation: A 42-year-old woman with severe preeclampsia and a history of intracranial vascular malformations underwent an emergency cesarean section.

NMF typing and machine learning algorithm-based exploration of preeclampsia-related mechanisms on ferroptosis signature genes.

Background: Globally, pre-eclampsia (PE) poses a major threat to the health and survival of pregnant women and fetuses, contributing significantly to morbidity and mortality. Recent studies suggest a pathological link between PE and ferroptosis. We aim to utilize non-negative matrix factorization (NMF) clustering and machine learning algorithms to pinpoint disease-specific genes related to the process of ferroptosis in PE and investigate likely underlying biochemistry mechanisms.

Background: The objective of this study was to evaluate the levels of Vascular Peroxidase 1 (VPO1), humanin, and MOTS-c in relation to miR-200c expression in untreated preeclamptic pregnancies, and to compare these findings with endoglin levels.

Methods And Results: In this study, blood samples were collected from preeclamptic patients presenting to the clinic prior to the initiation of treatment. The levels of endoglin, VPO1, humanin, and MOTS-c were measured using enzyme-linked immunosorbent assay (ELISA), while miR-200c expression was quantified using reverse transcription polymerase chain reaction (RT-PCR).

Causal associations of metabolic dysfunction-associated steatotic liver disease with gestational hypertension and preeclampsia: a two-sample Mendelian randomization study.

Background: Hypertensive disorders of pregnancy (HDPs), which include gestational hypertension (GH) and preeclampsia (PE), are the primary causes of maternal morbidity and mortality worldwide. Recent studies have found a correlation between metabolic dysfunction-associated steatotic liver disease (MASLD) and HDPs, but the causality of this association remains to be identified. Therefore, this study aims to evaluate the causal relationship between MASLD and HDPs through Mendelian randomization (MR) analysis.

Relationship between gestational body mass index, blood pressure variability, and postpartum depression in pregnant women with pre-eclampsia.

Background: Pre-eclampsia has long been proven to be an independent risk factor for postpartum depression (PPD). Excessive increase in body mass index (BMI) during pregnancy is an important factor inducing pre-eclampsia. Increased blood pressure is the main symptom of patients with pre-eclampsia.

She has incessant Torsade de Pointes treated with beta-blocker, lidocaine, overdrive pacing with a temporary transvenous pacemaker, left cardiac sympathetic denervation per video-assisted thoracoscopic surgery, and implantable cardioverter-defibrillator implantation.

THE APPROACH TO A PREGNANCY AFTER BARIATRIC SURGERY.

With a rising worldwide incidence of obesity, particularly in the young, bariatric surgery offers an effective method of meaningful and sustained weight loss. At present, most bariatric procedures are carried out in women and increasingly in younger age groups. In line with the fertility benefits associated with weight loss, pregnancy after bariatric surgery is now a very common scenario.

Do nutritional interventions before or during pregnancy affect placental phenotype? Findings from a systematic review of human clinical trials.

Background: Maternal nutritional interventions aim to address nutrient deficiencies in pregnancy, a leading cause of maternal and neonatal morbidity and mortality worldwide. How these interventions influence the placenta, which plays a vital role in fetal growth and nutrient supply, is not well understood. This leaves a major gap in understanding how such interventions could influence pregnancy outcomes and fetal health.

Exploring the Lifeline: Unpacking the Complexities of Placental Vascular Function in Normal and Preeclamptic Pregnancies.

The proper development and function of the placenta are essential for the success of pregnancy and the well-being of both the fetus and the mother. Placental vascular function facilitates efficient fetal development during pregnancy by ensuring adequate gas exchange with low vascular resistance. This review focuses on how placental vascular function can be compromised in the pregnancy pathology preeclampsia, and conversely, how placental vascular dysfunction might contribute to this condition.

Cargo exchange between human and bacterial extracellular vesicles in gestational tissues: a new paradigm in communication and immune development.

Host-bacteria and bacteria-bacteria interactions can be facilitated by extracellular vesicles (EVs) secreted by both human and bacterial cells. Human and bacterial EVs (BEVs) propagate and transfer immunogenic cargos that may elicit immune responses in nearby or distant recipient cells/tissues. Hence, direct colonization of tissues by bacterial cells is not required for immunogenic stimulation.

A review of clinical practice guidelines on the management of preeclampsia and nursing inspiration.

Objectives: To review, evaluate, and synthesize the recommendations of guidelines on preeclampsia (PE) from a nursing perspective.

Methods: This is a systematic review of international and national guidelines on PE. Electronic databases and related guideline websites were searched from 2013 to 2023.

Manganese exposure and perinatal health: a systematic review of literature.

Manganese is essential for adequate feto-maternal health; however, an inverted U-shaped relation has been found between maternal manganese status and pregnancy complications. This systematic review summarizes the effect of maternal manganese exposure and perinatal health. We adopted a systematic approach to retrieve the recent literature.

Immune changes in pregnancy: associations with pre-existing conditions and obstetrical complications at the 20th gestational week-a prospective cohort study.

Background: Pregnancy is a complex biological process and serious complications can arise when the delicate balance between the maternal and semi-allogeneic fetal immune systems is disrupted or challenged. Gestational diabetes mellitus (GDM), pre-eclampsia, preterm birth, and low birth weight pose serious threats to maternal and fetal health. Identification of early biomarkers through an in-depth understanding of molecular mechanisms is critical for early intervention.

Impact of maternal thyroid dysfunction on fetal and maternal outcomes in pregnancy: a prospective cohort study.

Background: Thyroid dysfunction in pregnancy can adversely impact maternal and fetal outcomes. However, the association between thyroid status and specific adverse outcomes needs clarity, especially in understudied regions.

Objective: This prospective cohort study aimed to illuminate the multifaceted associations between maternal thyroid dysfunction and feto-maternal outcomes in Gujarat, India.

Advancing diagnosis and early risk assessment of preeclampsia through noninvasive cell-free DNA methylation profiling.

Background: Aberrant embryo implantation and suboptimal placentation can lead to (severe) complications such as preeclampsia and fetal growth restriction later in pregnancy. Current identification of high-risk pregnancies relies on a combination of risk factors, biomarkers, and ultrasound examinations, a relatively inaccurate approach. Previously, aberrant DNA methylation due to placental hypoxia has been identified as a potential marker of placental insufficiency and, hence, potential (future) pregnancy complications.

Hypertensive disorders in pregnancy: Approach to diagnosis and management in general practice.

Background: Hypertensive disorders in pregnancy (HDIP) are among the leading causes of maternal and perinatal morbidity and mortality and should not be reserved for specialist care and expertise.1 General practitioners (GPs) are inevitably involved in the care of women with HDIP, particularly in the preconception, early pregnancy and postpartum periods and, also, as shared maternity care providers. It is, therefore, critical that GPs can assess and manage HDIP.

Management of Neonatal Hyperinsulinemic Hypoglycemia: Trends Over Nine Years.

Background: With increasing use of diazoxide for hyperinsulinemic hypoglycemia (HH), reporting of serious side effects of diazoxide such as pulmonary hypertension (PHT) increased.

Methods: Charts of all children diagnosed with HH during the study period and evaluated by Pediatric Endocrinology division of the Hasbro Children's Hospital were reviewed. We analyzed diazoxide use among infants with HH with focus on infants born small for gestational age (SGA) and preterm infants.

Implementation of maternal death audits and changes in maternal health care in Cambodia, 2010-2017.

Objective: Cambodia is one of seven countries globally that met Millennium Development Goal 5A: reduction of maternal deaths by at least 75% between 1990 and 2015. The maternal death audit (MDA) was instituted in 2004 to support the improvement of maternal care. We evaluated progress in MDA implementation and maternal health services in Cambodia between 2010 and 2017.

The role of DNA methylation in placental development and its implications for preeclampsia.

Preeclampsia (PE) is a prevalent and multifaceted pregnancy disorder, characterized by high blood pressure, edema, proteinuria, and systemic organ dysfunction. It remains one of the leading causes of pregnancy complications, yet its exact origins and pathophysiological mechanisms are not fully understood. Currently, the only definitive treatment is delivery, often requiring preterm termination of pregnancy, which increases neonatal and maternal morbidity and mortality rates, particularly in severe cases.
