TL;DR: An important role for NS1 is suggested in flavivirus RNA replication and pathogenesis because of the lack of N-linked glycans rather than the introduction of deleterious amino acid substitutions or disruption of cis-acting RNA elements important for RNA replication.

TL;DR: A list with nine families, 68 genera, and 178 species with documented occurrence in Brazil, including nomenclatural comments, has been compiled by the Committee of the List of Brazilian Bats.
Abstract: Lists of Brazilian bats have been compiled since the late 19th century, with remarkable variation in the criteria for species inclusion and use of nomenclature. To update the list of extant bat species that occur in Brazil, the Brazilian Bat Research Society created the Committee of the List of Brazilian Bats. Here we report the first result of the work of this Committee: a list with nine families, 68 genera, and 178 species with documented occurrence in Brazil, including nomenclatural comments. We also present two additional species lists: one with doubtful records (10 species) and other with erroneous records (six species). Since the beginning of the 21st century, 35 new bat species have been recorded for Brazil, and we anticipate that more species will be uncovered over the next years.

TL;DR: A high-resolution, global atlas of mortality of children under five years of age between 2000 and 2017 highlights subnational geographical inequalities in the distribution, rates and absolute counts of child deaths by age.
Abstract: Since 2000, many countries have achieved considerable success in improving child survival, but localized progress remains unclear. To inform efforts towards United Nations Sustainable Development Goal 3.2—to end preventable child deaths by 2030—we need consistently estimated data at the subnational level regarding child mortality rates and trends. Here we quantified, for the period 2000–2017, the subnational variation in mortality rates and number of deaths of neonates, infants and children under 5 years of age within 99 low- and middle-income countries using a geostatistical survival model. We estimated that 32% of children under 5 in these countries lived in districts that had attained rates of 25 or fewer child deaths per 1,000 live births by 2017, and that 58% of child deaths between 2000 and 2017 in these countries could have been averted in the absence of geographical inequality. This study enables the identification of high-mortality clusters, patterns of progress and geographical inequalities to inform appropriate investments and implementations that will help to improve the health of all populations.

TL;DR: Fecal samples from 194 individuals living in an area of Brazil endemic for Schistosoma mansoni were analyzed by a polymerase chain reaction (PCR) and the Kato-Katz parasitologic examination, demonstrating that the PCR assay might be a valuable alternative for diagnosing Schistsoma infections.
Abstract: Fecal samples from 194 individuals living in an area of Brazil endemic for Schistosoma mansoni were analyzed by a polymerase chain reaction (PCR) and the Kato-Katz parasitologic examination. Statistical analysis of the results showed a kappa index of 0.8 between the two methods. The prevalence of infection was 30.9% in three fecal samples examined by the Kato-Katz method, but 38.1% in one fecal sample examined by the PCR technique. Repeated survey of discordant results showed that five (41.6%) of 12 parasitologically negative cases for which PCR gave positive results were misdiagnosed by Kato-Katz examinations. The PCR technique showed a sensitivity of 96.7% and a specificity of 88% when the parasitologic examination was used as the reference test. The efficacy of cure with praziquantel was 87.8% in three parasitologic stool examinations and 75.6% in one PCR survey. These results demonstrate that the PCR assay might be a valuable alternative for diagnosing Schistosoma infections.
