A Pilot Study Exploring the Relationship Between Milk Composition and Microbial Capacity in Breastfed Infants.

Background: Maternal obesity may contribute to childhood obesity in a myriad of ways, including through alterations of the infant gut microbiome. For example, maternal obesity may contribute both directly by introducing a dysbiotic microbiome to the infant and indirectly through the altered composition of human milk that fuels the infant gut microbiome. In particular, indigestible human milk oligosaccharides (HMOs) are known to shape the composition of the infant gut microbiome.

[Strongyloidiasis as a cause of multiorganic failure].

Strongyloides stercoralis is a parasite that has the ability to reproduce within humans, which explains its persistence for many years. It lives in the duodenum and ileum, between the enterocytes, and opens up to the intestinal lumen. Historically it is associated with tropical and subtropical rural areas, but its development has been seen in microclimates that favour the biological cycle.

[Prevalence and underdiagnosis of burn out syndrome in critical services in the context of the COVID-19 pandemic].

Introduction: The importance of knowing the impact of work on people's health has increased after the COVID-19 pandemic. Burn Out (BO) syndrome arises from the tension emerging from the conflictive interaction between the worker and his or her employment. The objective was to describe the prevalence and frequency of diagnosis of BO in the health human resources of critical services of the Bahía Blanca Municipal Hospital in the context of the COVID-19 pandemic.

New approaches and error assessment to snow cover thickness and density using air temperature data at different heights.

Snow poles are inexpensive systems composed of a wooden mast with temperature sensors affixed at varying heights with the purpose of estimating the snow depth. They are frequently utilised in cold, remote regions where the maintenance of complex monitoring instruments becomes impractical. In this study, snow cover thickness is determined using different methods, based on the thermal behaviour of air temperature measured by a snow pole on Deception Island, Antarctica.

Asymmetrical nucleosomal DNA signatures regulate transcriptional directionality.

Despite the symmetrical structure of nucleosomes, in vitro studies have shown that transcription proceeds with different efficiency depending on the orientation of the DNA sequence around them. However, it is unclear whether this functional asymmetry is present in vivo and whether it could regulate transcriptional directionality. Here, we report that the proximal and distal halves of nucleosomal DNA contribute differentially to nucleosome stability in the genome.
