Severe COVID-19 in pregnant women: Analysis of placental features and perinatal outcomes.

Objectives: Changes in placental features, such as maternal and fetal vascular malperfusion, are associated with SARS-CoV-2 infection. The anatomopathologic study of the placenta is crucial for understanding pregnancy and fetal complications. To that end, this study aimed to describe placental features and analyze the association between placental findings and perinatal outcomes in a cohort of pregnant women with severe COVID-19.

Post-Traumatic Stress Disorder in Brazilian Pregnant Women at the Beginning of the Coronavirus Disease Pandemic.

Objective: Analyze the presence of PTSD symptoms and their risk among the pregnant women during the COVID-19 pandemic.

Methods: This is a cross-sectional study of pregnant women that received receiving prenatal care at two university hospitals in São Paulo, Brazil, during the COVID-19 pandemic, from April to June 2020. The sociodemographic and health data of the participants and their exposure to individuals suspected or confirmed to have COVID-19 were evaluated.

Perinatal Results and Long-Term Follow-Up of Fetal Cardiac Tumors: A 30-Year Historical Cohort Study.

Background: This was a 30-year retrospective cohort study that approximates closely to the natural history of cardiac tumors diagnosed in the fetus, since there was no case of pregnancy interruption.

Objective: To assess morbidity and mortality in the perinatal period and at long term in fetuses diagnosed with cardiac tumor. Our secondary objective was to assess the evaluating factors of perinatal and postnatal results.

Three-Dimensional Ultrasound Evaluation of Lung Volume in Fetuses with Abdominal Wall Defect.

Introduction: Abdominal wall defects (AWDs) interfere with postnatal respiratory parameters. We aimed to evaluate lung volume (LV) in fetuses with AWD using three-dimensional (3D) ultrasound (US) and to correlate AWD with the type (omphalocele and gastroschisis) and size of the defect and neonatal morbidity and mortality.

Methods: This prospective observational study included 72 pregnant women with fetuses with AWD and a gestational age <25 weeks.

Vaginal progesterone for preventing preterm birth and adverse perinatal outcomes in twin gestations: a systematic review and meta-analysis.

Objective: To evaluate the efficacy of vaginal progesterone for the prevention of preterm birth and adverse perinatal outcomes in twin gestations.

Data Sources: MEDLINE, Embase, LILACS, and CINAHL (from their inception to January 31, 2023), Cochrane databases, Google Scholar, bibliographies, and conference proceedings.

Study Eligibility Criteria: Randomized controlled trials that compared vaginal progesterone to placebo or no treatment in asymptomatic women with a twin gestation.
