Mixed Reality for Education (MRE) Implementation and Results in Online Classes for Engineering.

The COVID-19 pandemic has changed many industries, empowering some sectors and causing many others to disappear. The education sector is not exempt from major changes; in some countries or cities, classes were taught 100% online for at least 1 year. However, some university careers need laboratory practices to complement learning, especially in engineering areas, and having only theoretical lessons online could affect their knowledge.

Clinical isolates of Escherichia coli are resistant both to antibiotics and organotin compounds.

Antibiotic-resistant Escherichia coli are common causative agents of human urinary tract infections. Organotin compounds (OTCs) are man-made chemicals that may affect the renal function of exposed humans and rodents. OTCs are widely recognized as bactericides.

Evolution of care indicators after an early discharge intervention in preterm infants.

Objective: To evaluate the evolution of health outcomes in preterm infants included in an early discharge programme.

Method: Controlled, non-randomised trial with an intervention group and a control group children admitted to the Neonatal Intensive Care Unit of the University Hospital Virgen de las Nieves of Granada were included in the study. The intervention group comprised preterm infants admitted to the neonatal unit clinically stable, whose family home was located within 20km.

Impact of AmpC Derepression on Fitness and Virulence: the Mechanism or the Pathway?

Unlabelled: Understanding the interplay between antibiotic resistance and bacterial fitness and virulence is essential to guide individual treatments and improve global antibiotic policies. A paradigmatic example of a resistance mechanism is the intrinsic inducible chromosomal β-lactamase AmpC from multiple Gram-negative bacteria, including Pseudomonas aeruginosa, a major nosocomial pathogen. The regulation of ampC expression is intimately linked to peptidoglycan recycling, and AmpC-mediated β-lactam resistance is frequently mediated by inactivating mutations in ampD, encoding an N-acetyl-anhydromuramyl-l-alanine amidase, affecting the levels of ampC-activating muropeptides.

Comparison of local features from two Spanish hospitals reveals common and specific traits at multiple levels of the molecular epidemiology of metallo-β-lactamase-producing Pseudomonas spp.

Twenty-seven well-characterized metallo-β-lactamase (MBL)-producing Pseudomonas strains from two distantly located hospitals were analyzed. The results revealed specific features defining the multilevel epidemiology of strains from each hospital in terms of species, clonality, predominance of high-risk clones, composition/diversity of integrons, and linkages of Tn402-related structures. Therefore, despite the global trends driving the epidemiology of MBL-producing Pseudomonas spp.
