Article Abstract
SARS-CoV-2 infection in pregnancy and COVID placentitis are associated with an increased risk of stillbirth. We sought to investigate the presence of maternal viremia in people with SARS-CoV-2 infection during pregnancy who had histologic placentitis versus those without placentitis. SARS-CoV-2 qRT-PCR was performed on plasma from 6 patients with COVID placentitis and 12 matched controls without placentitis. SARS-CoV-2 infection occurred between 4/2020-1/2021; the latency between SARS-CoV-2 diagnosis and delivery was 0-76 days. Two placentitis cases demonstrated viremia (1 stillbirth and 1 well infant), while 12/12 controls were negative. Future research may consider viremia as a possible marker of COVID placentitis.

Similar Spatial Expression of Immune-Related Proteins in SARS-CoV-2 Placentitis and Chronic Histiocytic Intervillositis.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the placenta can lead to fetal distress and demise, characterized by severe trophoblast necrosis, chronic histiocytic intervillositis (CHI), and massive perivillous fibrin deposition. We aimed to uncover spatial immune-related protein changes in SARS-CoV-2 placentitis compared with CHI placentas and uncomplicated pregnancies to gain insight into the underlying pathophysiological mechanisms. Placentas were retrospectively collected from cases with SARS-CoV-2 placentitis resulting in fetal distress/demise (n = 9), CHI (n = 9), and uncomplicated term controls (n = 9).

Purpose: To investigate the impact of first-trimester COVID-19 infection on the perinatal and obstetric outcomes following in vitro fertilization-frozen embryo transfer.
Methods: This retrospective study was conducted at a university-affiliated IVF center. The infection group included women who contracted SARS-CoV-2 during the first trimester following frozen embryo transfer in China's initial pandemic wave that occurred from 7 December 2022 to 7 January 2023.

Severe Acute Respiratory Syndrome-Related Coronavirus 2 (SARS-CoV-2) infection during pregnancy was associated with a number of adverse pregnancy outcomes, including miscarriage, preeclampsia, preterm birth, and stillbirth. The virus persistence can last for a long time, and the consequences of a previous coronavirus infection are currently under study. This study aimed to establish the clinical features of the course of pregnancy and childbirth in women with a history of asymptomatic coronavirus disease 2019 (COVID-19).

Objectives: To study the rates of abnormal placentae and associated adverse perinatal outcomes in pregnant women who had COVID 19 infection during pregnancy, remote from delivery. To study the histopathological findings associated with these abnormal placentae.
Methods: A prospective cohort study was carried out, recruiting pregnant women with singleton gestation, who had COVID 19 infection during their pregnancy, remote from delivery between August 2021 to July 2022.

Introduction: Children with wheeze and asthma present with airway epithelial vulnerabilities, such as impaired responses to viral infection. It is postulated that the in utero environment may contribute to the development of airway epithelial vulnerabilities. The aims of the study were to establish whether the receptors for rhinovirus (RV), respiratory syncytial virus (RSV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are expressed in the amniotic membrane and whether the pattern of expression is similar to newborn nasal epithelium.
