Pediatric Ventilation Liberation: Bundled Extubation Readiness and Analgosedation Pathways Decrease Mechanical Ventilation Duration and Benzodiazepine Exposure.

Background: Recent studies reported that children on mechanical ventilation who were managed with an analgosedation approach and standardized extubation readiness testing experienced better outcomes, including decreased delirium and invasive mechanical ventilation duration.

Methods: This was a quality improvement project in a 24-bed pediatric ICU within a single center, including subjects ≤ 18 years old who required invasive mechanical ventilation via an oral or nasal endotracheal tube. The aim was to decrease the invasive mechanical ventilation duration for all the subjects by 25% within 9 months through the development and implementation of bundled benzodiazepine-sparing analgosedation and extubation readiness testing clinical pathways.

Challenging Convention: Daytime Versus Nighttime Extubation in the Pediatric ICU.

Background: The majority of pediatric extubations occur during day shift hours. There is a time-dependent relationship between mechanical ventilation duration and complications. It is not known if extubation shift (day vs night) correlates with pediatric extubation outcomes.

Microbial gas vesicles as nanotechnology tools: exploiting intracellular organelles for translational utility in biotechnology, medicine and the environment.

A range of bacteria and archaea produce gas vesicles as a means to facilitate flotation. These gas vesicles have been purified from a number of species and their applications in biotechnology and medicine are reviewed here. sp.

Agrichemicals and antibiotics in combination increase antibiotic resistance evolution.

Antibiotic resistance in our pathogens is medicine's climate change: caused by human activity, and resulting in more extreme outcomes. Resistance emerges in microbial populations when antibiotics act on phenotypic variance within the population. This can arise from either genotypic diversity (resulting from a mutation or horizontal gene transfer), or from differences in gene expression due to environmental variation, referred to as adaptive resistance.

Herbicide ingredients change sv. Typhimurium and antibiotic responses.

Herbicides are frequently released into both rural and urban environments. Commercial herbicide formulations induce adaptive changes in the way bacteria respond to antibiotics. sv.

The Aspergillus fumigatus farnesyltransferase β-subunit, RamA, mediates growth, virulence, and antifungal susceptibility.

Post-translational prenylation mechanisms, including farnesylation and geranylgeranylation, mediate both subcellular localization and protein-protein interaction in eukaryotes. The prenyltransferase complex is an αβ heterodimer in which the essential α-subunit is common to both the farnesyltransferase and the geranylgeranyltransferase type-I enzymes. The β-subunit is unique to each enzyme.

A Fungus-Specific Protein Domain Is Essential for RasA-Mediated Morphogenetic Signaling in .

Ras proteins function as conserved regulators of eukaryotic growth and differentiation and are essential signaling proteins orchestrating virulence in pathogenic fungi. Here, we report the identification of a novel N-terminal domain of the RasA protein in the filamentous fungus . Whereas this domain is absent in Ras homologs of higher eukaryotes, the N-terminal extension is conserved among fungi and is characterized by a short string of two to eight amino acids terminating in an invariant arginine.
