Rapid Colorimetric Detection of Zika Virus from Serum and Urine Specimens by RT-LAMP (Reverse Transcription Loop-Mediated Isothermal Amplification).

The Zika virus (ZIKV) can be passed from a pregnant woman to her fetus. Resulting infection by this virus can cause early miscarriage and a pattern of severe birth defects in fetuses and infants. Therefore, a rapid diagnostic assay that can be performed throughout pregnancy in a clinical setting is vital for prenatal care of women living in areas where this virus may be transmitted.CDC has developed a RT-LAMP assay for the rapid screening of ZIKV RNA from urine and serum. As few as 10 copies of ZIKV RNA per microliter can be detected using this assay, showing that it is highly sensitive. It was also shown to be highly specific for ZIKV RNA when tested against a panel of urine samples spiked with other flaviviruses such as dengue virus sub-types 1-4, West Nile virus, St. Louis encephalitis virus, and chikungunya virus, most viruses that circulate in the same geographic regions as ZIKV. This assay offers a rapid, reliable, sensitive, and specific means to detect ZIKV that can be performed in a clinical point-of-care (POC) or field setting with minimal equipment and technological expertise. The assay is fast to set up and perform (total time 1 hour). Additionally, it is approximately as sensitive and specific as RT-PCR detection methods. Thus far, 178 clinical samples collected from the 2015/2016 Zika virus outbreak were tested using this assay. CDC is currently working with a group to test a prototype point of care (POC) test in a clinical setting and develop a POC.IC: CDC...

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: Jang Y, Kim DW, Yang KI, Byun JI, Seo JG, No YJ, Kang KW, Kim D, Kim KT, Cho YW, Lee ST, Drug Committee of Korean Epilepsy Society Abstract Autoimmune epilepsy is a newly emerging area of epilepsy. The concept of "autoimmune" as an etiology has recently been revisited thanks to advances in autoimmune encephalitis and precision medicine with immunotherapies. Autoimmune epilepsy presents with specific clinical manifestations, and various diagnostic approaches including cerebrospinal fluid analysis, neuroimaging, and autoantibody tests are essential for its differential diagnosis. The diagnosis is o...

Conclusions Apart West Nile virus (78), thousands of congenital microcephaly cases, fetal brain tissue damage and neurological syndromes have been associated with ZIKV infection. Unfortunately, the epidemics of this mosquito born, and a relative stable virus is on a rise. Although congenital microcephaly is a rare disorder however, due to lack of standardized diagnostic test facilities, the incidence in the geographically widespread ZIKV epidemic regions is higher. Animals studies showed that ZIKV is a neurotropic virus. It directly targets the developing embryonic brain cells by inducing apoptosis, cell-cycle arrest, and...
