Reduced SARS-CoV-2 entry factors and enhanced innate immune gene expression in the nasal epithelium of pregnant rats

An enigmatic epidemiological feature of the ongoing COVID-19 pandemic is the high rate of asymptomatic infection in pregnant women.1 This is puzzling because systemic immune changes predispose pregnant women to increased severity of respiratory viral infections, especially influenza A.2 A major roadblock in understanding this atypical clinical presentation is the poor characterization of cellular entry factors for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) — angiotensin-converting enzyme 2 (ACE2) and the androgen-sensitive transmembrane protease serine 2 (TMPRSS2) — in the respiratory tract during pregnancy.

Conclusions: This review results revealed a low utilization of postnatal care service. Antenatal care service utilization has a positive effect on postnatal care service utilization. Policymakers and programmers better considered more antenatal care service use as one strategy of enhancing the utilization of postnatal care service. PMID: 33029402 [PubMed - in process]

Authors: Debelew GT Abstract Despite several efforts globally, the problem of perinatal mortality remained an unsolved agenda. As a result, it continued to be an essential part of the third sustainable development goals to end preventable child deaths by 2030. With a rate of 33 per 1000 births, Ethiopia has the highest level of perinatal mortality in the world. Thus, determining the magnitude and identifying the determinants are very crucial for evidence-based interventions. A community-based longitudinal study was conducted in Southwest Ethiopia among 3474 pregnant women to estimate the magnitude of perinatal mort...

In January of this year, oblivious of the fact that we were about to engage in a twisted round of real-life Jumanji, we released our annual digital health trends e-book. Among one of our 12 forecasts for 2020 was that at-home blood tests would gain traction and become the new direct-to-consumer DNA testing in terms of adoption and availability. While the pandemic threw everyone off guard and messed up regular forecasts, we might have been onto something with our predicted trend. With the need to limit physical contact and trace COVID-positive individuals rapidly, public health authorities worldwide are finding rapid, po...

The global pandemic of SARS-CoV-2, the cause of Coronavirus disease 2019 (COVID-19), has been associated with worse outcomes in several patient populations, including the elderly and those with chronic comorbidities. Data from previous pandemics and seasonal influenza suggest that pregnant women may be at increased risk for infection-associated morbidity and mortality. Physiological changes in normal pregnancy and metabolic and vascular changes of high-risk pregnancies may affect pathogenesis or exacerbate the clinical presentation of COVID-19.

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has spread rapidly across the globe. In contrast to initial reports, recent studies suggest that children are just as likely as adults to become infected with the virus but have fewer symptoms and less severe disease. In this review, we summarize the epidemiologic and clinical features of children infected with SARS-CoV-2 reported in pediatric case series to date. We also summarize the perinatal outcomes of neonates born to women infected with SARS-CoV-2 in pregnancy. We found 11 case series including a total of 333 infants and children. Overal...

Despite 2.5 million infections and 169,000 deaths worldwide (current as of April 20, 2020), no maternal deaths and only a few pregnant women afflicted with severe respiratory morbidity had been reported to be related to COVID-19 disease. Given the disproportionate burden of severe and mortal respiratory disease previously documented among pregnant women following other related coronavirus outbreaks (SARS-CoV in 2003 and MERS-CoV) and influenza pandemics over the last century, the absence of reported maternal morbidity and mortality with COVID-19 disease is unexpected.
