Unlabelled: To evaluate the accuracy of the lung ultrasound score (LUS) in predicting ventilatory weaning failure during neonatal hospitalization in the NICU and to identify factors associated with weaning failure, including corrected gestational age (CGA). This prospective, longitudinal, pragmatic and observational cohort study included neonates on mechanical ventilation for at least 48 h. The primary outcome was the accuracy of lung ultrasound in predicting 3-day weaning failure, with the ROC curve used to determine the best LUS cutoff (sensitivity and specificity).

Burgers have become a staple of global cuisine and can have several different versions and combinations. For example, hybrid burgers have a percentage of animal protein in their formulation, while plant-based burgers contain 100% plant-based proteins. Therefore, the aim of this study was to investigate the emerging trends and challenges in the formulation of hybrid and plant-based burgers, with an emphasis on new ingredients and the evaluation of their physical, chemical, and sensory properties.

The contamination of seas, rivers, lakes, and groundwater by industrial, hospital, and domestic effluents is a global health problem. Scientific approaches are needed to assess and mitigate the impacts of those pollutants, seeking more sustainable alternatives that meet established environmental standards. Among the various contaminants that are released into water sources, phenobarbital (PHEN), a long-acting barbiturate, applied as a hypnotic, sedative, and in the treatment of seizures is an aquatic pollutant, raises significant concerns for human health and the environment.

Background: The physiopathology of sarcopenia shares common biological cascades with the aging process, as does any other age-related condition. However, our understanding of the interconnected pathways between diagnosed sarcopenia and aging remains limited, lacking sufficient scientific evidence.
Methods: This narrative review aims to gather and describe the current evidence on the relationship between biological aging determinants, commonly referred to as the hallmarks of aging, and diagnosed sarcopenia in humans.
