[Seroprevalence of Hepatitis B virus in pregnancy women at the time of delivery].

Unlabelled: Worldwide, there is an alert due to the increase in the seroprevalence of hepatitis B virus (HBV). This can cause up to 3.5% of chronic diseases, of which 40% present secondary complications and/ or early death.

Contrasting Patterns of Genetic Diversity and Divergence Between Landlocked and Migratory Populations of Fish , Evaluated Through Mitochondrial DNA Sequencing and Nuclear DNA Microsatellites.

species are interesting biogeographic models due to their distribution and different types of life cycles, with migratory and landlocked populations. To obtain a better understanding of the genetic consequences of the Quaternary glacial cycles in , in this work we compared landlocked and migratory populations collected in areas that were differentially affected by ice advances and retreats. We included nine populations of , four collected from lakes (landlocked) and five from their associated estuaries/rivers (migratory) in three estuary-lake systems across southern Chile.

Gonadal cycle, reproductive indices and detection of parasitism in the clam Ameghinomya antiqua in natural beds of importance for fisheries.

The clam Ameghynomia antiqua is a highly important resource for fisheries due to its high catches volume. It is the bivalve mollusc with the highest fisheries landings from natural beds on the Pacific coast of southern South America; however, studies of the reproductive conditions of this species are scarce and date back many years. The object of the present work was to evaluate the reproductive characteristics of the species, analysing its gametogenic and gonadal cycle, and reproductive indices, in fishery locations that present the natural beds with the highest fisheries catches, as well as parasite loads in the species.

Antibiotic Stewardship in the Neonatal Intensive Care Unit: Effects of an Automatic 48-Hour Antibiotic Stop Order on Antibiotic Use.

Background: Meeting antibiotic stewardship goals in the neonatal intensive care unit (NICU) is challenging because of the unique nature of newborns and the lack of specificity of clinical signs of sepsis. Antibiotics are commonly continued for 48 hours pending culture results and clinical status. The goal of this study was to examine if the implementation of a 48-hour automatic stop (autostop) order during NICU admissions would decrease antibiotic use at UnityPoint Health-Meriter.
