Zika Virus VLP (Virus-like Particle) Antigens for Vaccine Candidate and Diagnostic Development

Zika virus (ZIKV) is a flavivirus primarily transmitted by infected Aedes mosquitoes. Infection with ZIKV during pregnancy can affect the fetus causing microcephaly, neurological complications, and other birth defects. Adults are also at a heightened risk of developing Guillain-Barre syndrome and other neurological disorders. In response to the 2015-2016 Zika outbreak, CDC scientists developed a recombinant vaccine candidate as well as reagents and methods to detect ZIKV infection. The recombinant vaccine candidate utilizes adenovirus vector expressed viral envelope proteins. This vector-based vaccine candidate is an efficient platform that elicits a strong response in mouse models; added vaccine testing in rabbit models is underway. Virus-like particles generated from the vector are also being used for ZIKV diagnostics. The US Food and Drug Administration (FDA) has issued an Emergency Use Authorization (EUA) for CDC's Zika IgM antibody capture enzyme-linked immunosorbent assay (Zika MAC-ELISA) that utilizes VLP technology for in vitro qualitative detection of human IgM antibodies to Zika virus in serum. It can also be used to test cerebrospinal fluid (CSF) when submitted with a patient-matched serum sample. The CDC Zika MAC-ELISA assay is currently in use at qualified laboratories designated by CDC.IC: CDCNIH Ref.

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.
