Viral Hemorrhagic Fevers in Pregnant Women and the Vaccine Landscape: Comparisons Between Yellow Fever, Ebola, and Lassa Fever

AbstractPurpose of ReviewAs research efforts have advanced to understand the pathophysiology of viral hemorrhagic fevers (VHF) and other epidemic viral infections and develop medical countermeasures such as vaccines, pregnant women have remained an underexamined subgroup. To better understand the implications of future outbreaks of VHF for pregnant women amidst an evolving vaccine landscape, we examine three pathogens —yellow fever, Ebola, and Lassa fever—each with different levels of evidence and understanding of disease in pregnancy and at varying stages of vaccine development.Recent FindingsThere are very limited data available on yellow fever disease in pregnancy and the current live-attenuated 17D yellow fever vaccine is recommended for pregnant women at high risk of exposure. Evidence on Ebola virus disease in pregnancy shows very high case fatality rates (CFRs) among pregnant women and their infants, with mixed evidence on whether mortality is higher in pregnant women than non-pregnant adults. The replication-competent rVSV-ZEBOV vaccine is currently being offered to at-risk pregnant women in the Democratic Republic of the Congo after a revision to an earlier protocol that excluded them. For Lassa fever, there is evidence that CFR is higher in pregnant individuals than non-pregnant adults, especially later in gestation, with high rates of fetal or perinatal loss associated with infection. There are currently no Lassa fever vaccine candidates that have been ...

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...

This study was aimed at assessing the magnitude of induced abortion and associated factors among students in Hawassa University, southern region, Ethiopia, 2019. Methods: An institutional-based cross-sectional study was conducted among a total of 422 students selected on the bases of a probability simple random sampling method. A pretested structured questionnaire was used to collect data. Analysis was made with SPSS 20. Descriptive summary and inferential statistics (binary logistic regression) were used with a 95% CI and P value of less than 5% as a level of significance. Findings were presented in tables, figure, an...

Conclusions: (1) Data at our center suggests at least a regional implementation gap in GBS screening and IAP. (2) The decline in the resistance rate ofE. coli for all antimicrobial substances might indicate that the reduction of prenatal antibiotics use is beneficial and that neonatal antibiotic stewardship programs should include pregnant women as well.What is Known:• GBS screening and intrapartum antibiotic prophylaxis led to a 32%-reduction in GBS disease in Germany with a 0.75 (92:122) ratio of early-onset disease to late-onset disease in 2009–2010.• Prenatal antibiotic use might increase the risk of E....

In this study, we explored its health effects on the female offspring of mice that had been exposed during pregnancy. We found that exposure of pregnant mice to nitenpyram resulted in decreased levels of serum triglycerides, total cholesterol, and glucose in female offspring, and additional research uncovered gut microbiota disturbances, accompanied by abnormal fecal metabolic profiles. Based on Pearson correlation analysis, we found that decreased abundance of Lactobacillus may play the most critical role, and changes in gut bacterial purine metabolism, BCAAs metabolism, and the TCA cycle are all closely related to the ab...

Authors: Fentie K, Wakayo T, Gizaw G Abstract Background: Anemia defined as a low blood hemoglobin concentration is public health importance. The adolescence age group is the most neglected in public health and nutrition research as priorities are usually given to pregnant women, lactating mothers, and their children less than 2 years. Current Ethiopian Food and Nutrition policy included adolescent girls in the most at-risk group for nutritional demands; however, only a few published studies have assessed a deficiency of anemia and associated factors to tackle the intergenerational cycle of malnutrition.
